Long-Term Review: Anker SOLIX F1200 (757 PowerHouse)

In this video, I discuss the Anker 757 PowerHouse. This is a long-term test video after using it for over four months.
Conclusion: It's a solid battery station, with a very simple but functional design, a long warranty, and design service life, so long as you are not bothered by the issues I encountered in the video.
I am planning more detailed videos on a few related topics in the near future pertaining to efficiency calculations, charging via solar, and power conversion topologies. So stay tuned!
My apologies for any construction noise in the video. I had to record in a place where I haven't before, due to the size of the battery, and there was ongoing construction that could not be avoided. Hopefully, the noise reduction worked!

Excellent review! Appreciate you taking the time and effort for this review. Big help!

[@TheCuriousEngineerChannel]

Thank you very much!

[@Hikebike365]

Wow great review!

[@jackwiegmann]

Thanks for the honest, informed review. I'm not sure if I can find it -- do you make the video about charging solar power?

I'm a big fan and user of Anker products. The only benefit for me for this large battery bank vs my GoSun 1100 is that it's LifePO4 and it charges to 80% in 1 to 1.5 hours. Otherwise,.it's twice the size of my GoSun 1100 and only 100 wh more in capacity. The Anker has more ports but I wish their smaller versions had all the features of this one. I use my GoSun 1100 in our tent for 3 to 5 day race weekends for my kids' motocross races. My car is a plug in hybrid with 2 x 1500 watt outlets, so I have an extension cord going into the tent to keep the Go Sun topped up on the second day while the GoSun is connected to our fridge. I have my 100 watt solar panel connected to another battery further down from our main tent. So charging up quickly could really cut down many hours throughout the day and shifting my power cable to other parts of our camp.

Great review I have this unit myself bought it a few months ago along with the one just under it the 555 and both have been good units so far for me. The 555 has the converter on the outside attached to the power cord and it takes about 5 hours to charge so that was sorta a disappointment but not a deal breaker for me. I've been using anker power banks for years and have only had one to go bad within the warranty period and anker replaced it quickly and hassle free witch is why I like them so much. Alot of companies make you jump through hoops to get a replacement product but not them. They also just released the 767 model powerhouse too witch looks very nice although I don't really see the point of having 3 of them though. A few things I wish this unit had was wireless charging pad with the flat surface on top I think that would have been a perfect place to have one and also app control. The 767 has a app but not this one or the 555. All in all it's still a pretty good unit in my opinion and I don't regret buying it. Oh I was also curious about the fan and cell configuration on this unit and how many it had of each so I'm glad you explained that too.

[@chrisjames7015]

Excellent review. I watched this review and decided to purchase the 757. I really like it. I have noticed higher self discharge on my Anker 757 than my Anker 535. Please can you confirm the level of self discharge you are seeing when the unit is left unused for 1 week / 1 month. I have all outlets off and power saving mode on. Storing it at about 20C. The only explainable difference I can see is the 51V battery setup in the 757 vs 16v battery setup in the 535. I might try fully discharging and recharging to see if that helps. Thanks in advance for any information you can provide as a comparison. Keep up the good work, great channel.

[@TheCuriousEngineerChannel]

I have noticed a slight drop in the reported charge level if the battery is left for a few days without being used on the 757. That is, if I press the display button, I might see it drop 1% every few days. I did let it sit for a week off charge at 100%, and it continued to report 100% no matter how many times I pressed the display button. I charge it primarily over solar, and I've noticed it jump from ~70% -> 100% at times. At this point, I attribute that to the BMS not being that super accurate or perhaps it is erring on the side of underreporting SoC, and not a higher self-discharge. Perhaps I'll do testing on it at some point. Thanks for watching!

Thank you! The video coming up involves using the Anker 757 with the Renogy panels and setup that I have; not Anker's solar panel offering. That video will be out soonish. 🙃

[@JeffMuhlbach]

@@TheCuriousEngineerChannel looking forward to that. I want solar panels but the anker panels are a bit expensive

[@user5871]

Whats the noise like when recharging?

[@jio-lito]

How fast does the unit discharge on its own?

[@priceks]

When charging from a standard wall outlet does it require sufficient power to utilize the HyperFlash technology, or can this be also charged from 120v power source with less amps (i.e. a really small generator, a 750w inverter on a deep cycle battery, etc)? I understand I could use the 12v DC input to charge it from the deep cycle, but what I'm asking is whether the 120v standard wall outlet REQUIRES 12A to operate, or whether it can run on far less (i.e. 120v at 2 amps such as a 120v inverter outlet found in many vehicles today). You mentioned that if you plug this into a circuit with other devices it'd likely overload and blow the breaker, so I imagine it requires the full HyperFlash amperage.

[@TheCuriousEngineerChannel]

It will only charge at 1000W. As soon as I tried to charge it off a 500 Watt Pure-Sine Wave inverter it overloaded and shutdown. So, its a no go on most integrated vehicle power inverters. But in the car you can use the 12V @ 10A car charger. Which, yes, it’s slower, but it will still charge. Great question and thanks for watching!

[@mauropotiguar]

I've seen someone using a converter in a car and using an adaptor to use the solar input to charge super fast.

I have been using the Anker 757 Power House for approximately 1 month and using 1- 200 W Grecell solar panel, max load V: 19.8V, max load current: 10.1A. It charges great! I am told I should only use 100 w panels in parallel not to exceed 300w. Is this a problem?

[@TheCuriousEngineerChannel]

Glad it's working for you! I am making a video on this topic. It will be up soon!

[@larryseibold4287]

Can this 757 be charged with solar or 24vdc 10A while being used to dramatically extend its run time? I assume that this device limits the charge current draw to what it wants vs needing the battery or solar array to do so?

[@maartenvt]

the consumer power is fixed. It just asks that and the battery delivers. There will be a shut down if it exceeds the battery capacity. The solar module just charges the battery and if the power of the consumer is over 240W, it wil discharge the battery. If the consumption power is under 240W, and the solar module gives full power, the battery is charged while you discharge with the consumer. I'm not taking the efficiency losses in account. so it's theoretically to give you an idea. So the solar power is definitely giving you extra Wh that extends the run time.

[@LucWijdeveld]

Bought the Anker SOLIX F1200 Solar Generator (=Powerhouse 757) + 100W Solar , now with 300 euro discount Anker spring sale offer, payed 799 euro bundle price

[@sociopathmercenary]

Have you looked at how clean the power output is for the inverter with an oscilloscope? I've seen a couple reviews that indicated the power delivered may cause some problems with certain devices such as pumps and transformers... Along with some light flickering on some models.

[@jamiedeegaley9000]

Have you recorded the solar charge review video of this yet? yet?

[@TheCuriousEngineerChannel]

I am working on it. I want to devote more time to this channel, but YT is making it quite challenging monetarily.

[@rtronick]

Sent mine back. It wouldn't power my 12v Iceco JP40. It would reach desired temp, then the Anker would shut off. Power Saver was off. Anker support was a nightmare!!

[@DennisMathias]

Why wouldn't all the 120v outlets be grounded outlets that can accept that type of a plug?

[@TheCuriousEngineerChannel]

Hmmm....perhaps a good topic for a video. But in short many of the plugs, at least in the US, are polarized plugs (two prong).

[@portfolioso]

Anker says this does not support pass through charging. Is this true? Would I be able to run this with solar panels constantly connected?

[@TheCuriousEngineerChannel]

That is a great question. It does and it doesn't. It's something that I am aiming to cover in a video soon.

[@portfolioso]

@@TheCuriousEngineerChannel looking forward to it. This is a hard requirement for me, even if it trickle charges or helps it discharge less.

[@analytic85]

I bought this device, but some issues are making me feel like I have a defective unit. I noticed whenever I charged it to 100%, it seems to drop Way too fast for something that has no load. Yes, everything was turned off. Is there a certain threshold, before it starts to show you power draw on the display screen? I noticed on the powerhouse 800 I can see something drawing 12 watts etc. on the 757, I had to get to almost 20 watts before it would even show anything, and the time remaining doesn’t seem to be accurate either. The powerhouse 800 was showing more time remaining, then the 757. The power house 800 is 500 watts max around 700wh for comparison.

[@TheCuriousEngineerChannel]

Right, the 757 does not show its quiescent (internal) power draw on the screen, unlike the other PowerHouse's you mention. The AC inverter uses around 25-35 watts, and the DC-DC conversions use around 1-5 watts (depending on what is being used). I don't feel it's "defective", because as I've mentioned in the video, the percentage does seem to jump down in large steps sometimes. I've experienced similar, but less pronounced behavior on the other PowerHouses that I have. Also it is important to take into account the power factor the load that is being run from it. I'll be discussing this more in a future video. Thanks for watching!

[@michaeljuers574]

Do a long long review after the warranty expires. To quote customer service “We currently do not have a repair service for Anker Power Station. But we do offer an exchange when an item is defective within the warranty.” Are you willing to risk that much money for a product that could be impossible or extremely difficult to repair. Time for all these reviewer’s to put the multi meters away and take a big picture look at buying any of these units. I’d take a half assed unit I could get repaired over time. I have a 2 1/2 year old dead Bluetti I cannot get repaired.
