I appreciate a product review where real measurements are taken. Nothing frustrates me more than seeing words like “lightweight” or “it’s great” thrown around.

Ya, those general terms get used a lot without any real numbers behind them. I’m not a fan of that either. Thanks so much for your comment!

[@InvestorAcademyPodca]

Great review, I have one Anker and one Nitecore. I do prefer the Nitecore due to not having to carry a micro USB cable and having two outputs. Having a USB-C output allows me to only carry one cable to charge and recharge everything I carry. For weight, yeah, it's not appreciable by itself. The only thing is that if I have 20 items in my pack and they all weigh 30 grams more, I'm almost a pound and a half heavier. That said, $35 to save 30 grams isn't the best bang for the buck and if that was the only difference I would probably stick with the Anker.

[@DoseofDirt]

Thanks for sharing this perspective! I know some have had issues with the Nitecore. Sounds like yours has been all good though? You're absolutely right that if every gear item you take is 30 grams (or 20% heavier than a cheaper option) you end up with a heavy pack QUICK! Maybe I'll feel differently in a few years if I've converted more to USB-C. I'm glad the Nitecore works for you. Thanks again for sharing your perspective.

[@samocooper9070]

Good to see your stance on free gear, given the cost of branded gear its going to be an expensive choice but worth it for the viewers. Seeing other channels its pretty clear they are tainted by the free stuff they get, even if just subconsciously.

[@jamespapp]

Excellent video. I really enjoy your style; you're level-headed, detail-driven, firm-but-fair, and an overall down-to-earth guy. That's what makes me want to help out all the more with the evil mAh misconception that plagues any kind of discussion concerning battery banks. I really did try to do this with as few words as I could... Power (measured in Watts, with the symbol W) = Volts (V) x Amps (A). mAh (the common but misleading measure of a battery bank's capacity) is a measure of (thousandths of) Amps over a number of hours, i.e. mAh = 0.001 x A x h. However, Work (Wh) = W x h = V x A x h = V x 0.001 x mA x h. You can see how the work a battery can do is only partly represented by the Ah, but completely represented when you also specify the voltage. In other words, a battery bank's capacity is meaningless unless you also know the voltage at which it operates. When these awesome battery bank companies (and they ALL do it) quote their bank's capacity of 10,000 (or whatever) mAh, they neglect to tell you that that is with respect to the voltage of the cells within the bank (typically cylindrical 18650's, hence the shape of the Anker bank) which operate at 3.7 V. However, as the Nitecore bank instead uses pouches operating at 3.85 V, that's why you see a 38.5 Wh rating on the Nitecore bank = 3.85 x 0.001 x 10000 x 1. This actually goes a long way to explaining the difference in weight between the banks. Using the lower-voltage steel-encased 18650's makes the Anker slightly heavier, but they're much more readily available, hence much cheaper. No criticism here, just two different ways to build a battery bank. When charging the banks, you will always see more juice is required than this rating (to fully charge them) because of the losses (to the environment in the form of heat) incurred during charging (and also, in fact, during discharging). Why then do we see (at the 9:50 mark in your video) that the Nitcore only took 8926 mAh to charge it fully? That's less than 10000 mAh, right? Yes, but it took (in the same shot in the video) 44.67 Wh to charge it, which is 16% more than it actually holds. How does one explain this? Well, I truly expect the Klein numbers to be very accurate, and when you appreciate that that the charging voltage was actually ~5.14 V (that was just the final voltage-the voltage would actually have varied slightly over the course of the charging process) then you can see that you come out to ~45.88 Wh, almost exactly what was shown on the display. Does this tell us how much the bank holds? No, it really only tells us how much it took to charge it, but it is a good indicator (at least we were in the ballpark). BTW, losses anywhere from 10% to 20% are normal (less being better). So, what does that mean when comparing your charging results? Well, they're really pretty comparable. The fact that the Nitecore bank took a little more juice to fully charge it COULD mean it actually holds more (but necessarily). The fact that the Nitcore charged markedly faster, though, that is a positive takeaway for me. I think you made a very meaningful and useful comparison video. You really could choose either bank and be happy with your decision methinks! I hope this helps you and some of your viewers! Keep those videos coming!

[@rachelbrain]

The peanut butter made me 😂😂😂. So hyped that you're doing Patreon! I'm sure people can do honest reviews of gear they've gotten for free, but to me it feels more legit when people buy it just like everyone else would have to. It's not just ethics, I think having to actually hand over the cash makes estimating the value of an item easier. Like, of course I'd use all the super fancy stuff if it was free lol.

[@DoseofDirt]

Glad you liked the PB bit! 😂 Thanks for being excited about the patreon! I'm excited to do things that way as well! Nothing against the channels that get free gear, I just don't like doing things that way. I agree with you that having to actually pay for it (and weighing it against other things you could get with that same money instead) makes it just feel a bit different. I always look forward to your comments!

I like the USB-C input and USB-C output on the Nitecore, as it means I need to carry fewer cables. Agree with the sharp corners of the Nitecore, they also keep making holes in my bags. I now just filed them down, which worked.

[@juliomb1]

I have the Anker. I was planning to buy the Nitecore until I realized the Anker was practically the same weight. No reason to spend $60 then.

[@DoseofDirt]

Completely agree! I was excited about "the lightest power bank in the world" until I realized the Anker is basically the same. Weight of 6 starbursts! 😂 I have heard of others having problems with the Nitecore as well. I trust Anker!

[@one2869]

Seeing as I could buy 3 anker powerbanks for the price of 1 nitecore, I am sure for the same money, I would have tons more charging capacity. Although, it would come at a significant weight penalty. I would still choose the anker. I have heard of others having issues with the nitecore. I would rather carry a tiny but of extra weight knowing something was going to work vs. Something that may not be reliable.

[@DoseofDirt]

COMPLETELY agree! Anker gives me a lot more confidence and that is well worth the 30 grams. There are also much cheaper ways to save 30 grams than spending an extra $40 on a powerbank (that I have less confidence in anway)!

[@SuperdutyExplorer]

The usb-c charging is a big plus for me... ive only used the nightcore, I've had great luck with mine. I like that it's a lot slimmer so I can stick in any pocket I basically want. I've had to use the lock on feature for charging my headphones alone.

[@DoseofDirt]

Nice! Glad it's working for you. I know there are a lot of people that love it, so Nitecore must be doing something right!

[@LongBoy.0]

well-timed video. I was just about to buy a new power bank, and now I'm going to use your link for the Anker. I trust Anker and I've used a heavier 8 oz 10k anker in the past, so I'll stick with the name I know and get the lighter one. Ounces are pounds!

[@DoseofDirt]

Perfect! Thanks for using the link! This power bank has been so incredibly reliable. I seriously love it!

[@prepsolar787]

excellent video! i have the anker powercore II 10000mah powerbank with a anker 21watts portable solar panel. A awesome setup for those long hikes or camping nights the way i use the setup is i charge the power bank with the solar panel and then charge my phone or any other small electronics like earbuds with the powerbank. i do not charge my phone directly to the solar panel because of the volt and wattage fluctuating do to the shade of clouds or what not. and depending on weather conditions it takes about 5 to 6 hour's to fully charge

[@joni-ll6mj]

Interesting review. I have the nitecore NB10000 v2 and I am very happy. At the same time I have multiple Anker products (not this power bank) and they are usually good products. However, the Anker power bank in this review seems to be an outdated model. Micro USB is an absolute no go today. I think the only reason they can sell it is the very low price. And the price is low becasue micro USB turns me and many people away. This is a very fragile port and it requires to have a different cable or adapter that I try to get rid of completely now as nost devices today are USB-C. Maybe compare it with a newer Anker product with similar capacity. So overall I think the price difference is justified. It is not just the 30g but the port and faster charging and features like that.

[@neist]

That low-voltage charge mode is great for smartwatches. I always have trouble getting mine to charge.

[@lyndonlives638]

I actually carry the Nitecore in my backpack pretty much every day as its slim profile makes it easy to slip in a custom pocket in one of the backpack compartments, but maybe if I were going hiking I might use the Anker instead. Frankly they both seem pretty good!

[@Nikitafrom233]

One correction for the future: 42 wats was there. So both of the banks outperformed actually their rated capacity of 38.5 Wh. MaH make no sense at all without voltage. Thanks for the content)

[@yankfr]

Thank you for the video. I’m looking for lightweight powerbanks for a film project during a trek in Greenland. I’ll need to film during one of the treks, which will last 14 days without any electricity source. My camera requires a lot of batteries, so I plan to bring 5 V-mount batteries: Viltrox 99Wh 6700mAh/14.8V (or possibly FXLion, another brand). Logically, one Viltrox “should” help me cover 2 to 3 days of filming as long as I shoot around 2 hours a day max. The V-mount batteries are very heavy (550g each), and knowing we’ll be carrying 35kg over 200km in the mountains, I’m looking to add the lightest backup powerbanks possible to recharge these V-mount batteries via USB-C. That’s how I found the Nitecore 20,000mAh; I plan to bring 5 of them, but I’m unsure of their reliability and if they’d be sufficient to recharge my V-mount batteries - I think 75% efficiency is a good estimate? I’d be curious to hear your thoughts and advice if you have time. Thank you so much! 🙏 EDIT : I asked GPT, and here’s what it indicates: "If your Viltrox 99Wh has a USB-C PD-compatible input port, it can be recharged by a USB-C PD powerbank (between 65W and 100W). If it doesn’t have this port, then it would require a specific V-mount charger with a 16.8V input." Indeed, my V-mount battery has a USB-C PD port, but apparently, I’ll need a much more powerful (and therefore heavier) powerbank, which is unfortunately going to weigh down my pack 😅

[@calvin_E]

I've had a 20k mAh Anker for like 6 years, some how still going strong no lack. I bought a 10k mAh Anker about 2 years ago and it's going just as hard as my first. That alone has made me an Anker fan. Nightcore is for lightweight heavy hitting headlamps. I own both the old and new nu-25 and love them forever, best lightweight headlamps.

[@DoseofDirt]

Can't go wrong with an Anker powerbank! I love these 10K mAh I've got. Haven't lost any capacity over the years and I've never had a single issue with them out in the field. Completely agree with you on the NiteCore headlamps. That NU-25 is THE lightweight headlamp. I haven't found anything that rivals it.

[@pheint00]

The low voltage charge mode works for a night-light LED. 👍 The lower capacity of the powerbank compared to the stated value can be due to a couple reasons. There will be some loss with the energy transfer. It could be the efficiency of the electronics inside the unit, the resistance from the cables, or in the least desireable circumstance, an inferior battery. Keep the powerbank away from heat and cold as well. Both will send it to an early trashcan.

[@philippeayache9589]

The manufacturer mAh ratings are at the battery cell voltage of 3.7V (battery pack and phone). His measurements at the input and output are at the input/output voltage of the USB standard of 5V. Hence the lower mAh (conservation of energy). And yes the different between input and output are due to the roundtrip efficiency of the microelectronics in the battery pack.

[@flyffpsy]

4:06 I have GEN 3 of this PB and this will not work. Maybe they changed it? I was able to load my smart watch with 5v 0,15a without any issues.

[@chetters77]

I tried the NB10000 and after it left me stranded with no power I quickly returned it. If the power button is pressed for 10 sec it will shutdown, requiring external power source to power up. The button was pressed in my pack while hiking and was very frustrated to find I had no power for the remainder of the trip. Nitecore also knows about this flaw, I mean hidden feature and has no plans to fix it. I replaced this with the Anker Nano, a little over 7oz, but has a built in USB-C cable along with an additional USB-C and USB-A and still cheaper than Nitecore. Anker for the win.

[@DoseofDirt]

DANG! That sucks. You're not the first person I've heard from where the Nitecore left them stranded without power for one reason or another. Insane they know about the issue and won't fix it!

[@magixmagix]

Over the years I have accumulated over 20 powerbanks. Most of them become outdated, with insufficient charging speed or not having USB C port, only Nitecore powerbank bulged up and stopped charging.

[@eldiablo2044]

I was just shopping for power banks and comparing weights, and realized how insignificant the savings are with the nitecore. Theyre negligible as well compared to my iniu powerbank pound for pound with the 25000 mah powerbank. Even size wise its not that niticably smaller if you were. To stack them up

[@DoseofDirt]

Totally agree. I mean, if every team counts then nitrcore is a little lighter, but for me it’s just not worth the price. I can save 30 grams in so many other places for a lot less money!

[@melissasmess2773]

I prefer to buy a power bank box and flashlight that both use a 26650 rechargeable battery. That way I get to purchase the features I want and the best quality of battery possible and maintain both devices over the years, instead of throw them out when the batteries don’t work well any longer. Two of those batteries are 10,000 Milliamps 😊 Thank you!

[@DoseofDirt]

This is an excellent point. I recently got a headlamp (and bike headlight) that use the rechargable 18650 batteries. I am definitely a fan of that set up. That way I always have a charge and don't have to wait for something to REcharge.

[@mikeleone1347]

I have both, as well as an older Anker 20K battery. The Nitecore is a lot thinner, which comes in handy if you're carrying it around in an every day carry sort of bag, like a 2L waist bag or sling. Especially if you have to carry a personal phone and a work phone (you never see sling bag reviewers do that, which I think is much more common than they realize, I'm required to have my work phone available during non-office hours, and if I don't answer it, I can get in trouble ... ). 2 such phones, a battery pack, tissue or a bandana for those hots days, etc. The weight doesn't add up, but the *bulk* does. You end up with a very lumpy waist belt or sling ...

[@markall8641]

[@DoseofDirt]

Sounds like we're of the same opinion!

[@Julian-pg9dx]

Sorry, but you made a mistake here. You can't compare the power bank's capacity, it's rated capacity and your phone's capacity. The capacity (in mAh) depends on the voltage. When you read that a device has 10,000 mAh, or 3,274 mAh, like the iPhone 15 Pro, that always refers to the battery cell's voltage (~3.8 Volts). You can compare it to a car engine's RPM and torque, whereas the RPM is the voltage and the current is the capacity. Moving parts like the transmission cause the power inefficiency. An engine with high RPM and low torque can, in theory, have the same power as an engine with low RPM and high torque. You would compare HP to HP, so here you would have to compare Watt hours to Watt hours. Therefore: The true capacity is 38.5 Wh. Divide that by 5V and you get 7,700 mAh. Due to inefficiency, that number lowers to 6,400 mAh. But your phone converts that into its battery's voltage, so it's back to around 8,250 mAh, not accounting for the energy loss within the phone.

[@wkwong80]

I had both banks & ultimately returned the Nitecore reaching the same conclusion as you: it wasn’t worth it. The Anker is years old & an even better deal now.

[@VolfiMartin]

I bought Nitecore NB 10000 GEN 2 and was very disappointed. It is a very nice and small device. But three things no one mentions. 1. When I use 20w charging for a phone or tablet, the power bank gets extremely hot. I estimate the temperature to be over 55°C. 2. Because the power bank heats up like this, its efficiency will not be good, but I did not measure the efficiency. 3. When the last LED started to light up, the voltage of the powerbank started to drop from 12.03v to approx. 11v and then shut off even though it wasn't fully discharged.

[@tiagon19]

A Great feature to have is "pass through", so it allows you to carry an even lighter PowerBank, such as a 5.000mah, but along with a 130grams cheap semi-flexible solar panel of 9W, will give you endless hours of electricity. Since with pass through, you charge or devices while your micro powerbank charges from the sun! It works. Give it a try!

I recommend 2 Ankers with 5000 mAh, because this one has only one output or one with more outputs. A bit over 200 grams and a lot of advantages. Nitecore has no quality. A lot of people say that they are broken after a year or so.

[@Wayondon]

Anker PowerCore 10000 Portable Charger is currently $16.98 on Amazon.

[@Mo.Jo.]

It's not that the actual number of mAh it holds is less than advertised - its the actual amount it can deliver to your device as it depletes due to loss in conversion when you pull power from it. The power bank for sure holds exactly the advertised amount - as do all legitimate and non-fake power banks.

[@DoseofDirt]

I'm certainly no expert, but the meter seems to say differently. Either way, at the end of the day you're right that the power delivered from the bank to the device you're charging is what really matters, which is why I measured both.

[@GatorReeves]

I have a different perspective. If you receive a piece of gear for free, and you haven't promised anything other than an objective review, I think that is the optimal situation. If you buy something with your own hard-earned money, we may subconsciously prop up that gear so we don't feel like we wasted our money. What are we more likely to toss? Something we got for free, or something we researched tenaciously, and developed some feelings about it even before we used it?

[@DoseofDirt]

Interesting perspective. I don't think I've thought about it that way, but can definitely see where you are coming from. I know lots of channels and others who review things get free gear, I'm just not a fan of doing things that way.

[@GatorReeves]

in the UL community you can't just say 30g is almost nothing. it is more than a third of the weight of my backpack (86g, a Salewa Vector 25) ;-)

[@DoseofDirt]

You are absolutely right. There are some for whom 30 grams is a BIG deal, and paying an extra $40 to save that weight for similar (better?) performance and benefits would be a no brainer. That's just not my take on it. And I think for most backpackers out there, the cost savings is worth the additional 30 grams. But as with all things, we all have our own thoughts and approach. Thanks for being willing to share yours! Also, impressive that you get it all into a 25L pack. I am going to try using my 20L UD fastpack this summer for a few trips.

[@tomnoyb8301]

Isn't 30g 20% heavier? Most people carry about a hundred items backpacking. If each one weighed 30g more, that's 3kg = 6..6lbs. Otoh, paying $40 to lower the weight of each of those hundred items by those 30g would be $4,000, so the comparison might not be perfect? But it's not just the weight that makes Nitecore better, it's that its USB-c is "PD" (Power-Delivery), meaning it can figure-out the optimal voltage and current to utilize both when charging and when being charged. Fact is, if DoD had a better wall-charger, he should be able to charge the Nitecore from zero to full in 1hr and 36min. With similar advantages charging other devices. Where this author loves the Nitecore is when accepting power from a solar-panel, because unlike lesser power-banks, Nitecore recognizes it's being charged and sucks-in every electron being fed by the solar-panel. Have walked-out of the wilderness after 9-days and into town carrying a tiny 2W solar-panel with every device and the Nitecore fully charged. Attribute that (essentially) infinite trail-power capability to the Nitecore. May run out of food, but will never run out of power. ______________ Regarding the trickle-charge function, Nitecore shuts off automatically when a phone or other larger device is full, in order to save the power of feeding an already full device. However, some small devices can appear to be full when they won't accept much current. If you find your small devices weren't being fully charged, trickle-charge will ensure full-charging. User has to look for it, because everything appears normal upon initial plug-in and even when charging ends, but the small device may not be fully charged. Maybe it's only half-charged? It's worth checking. Otoh, leaving a device on a lesser power-bank may unduly deplete the power-bank? If say, someone were to leave a watch or earbuds on that Anker when they went to bed, they might find they'd lost a portion of the small device's capacity in the morning, and without even noticing. Leaving a larger device loses even more power. It's bad for the device and the user wonders why he's not getting as much out of his battery-bank as he expected.
