Is this the perfect Power bank for travelling? Ugreen 130W 5-20V

[@An.Individual]

Others will have said this but most airlines allow power banks up to 27,000 mAh for "additional batteries" without permission that are not for medical devices. Also you can take up to 2. PS larger are allowed to power medical devices. I think the FAA limit is 43,200 mAh

Best part about this power bank it can charge at 72 watts i love power banks that can fast charge also

[@An.Individual]

Looks great. The built in power meter display is a killer feature.

[@beer_goggler]

Couple of things. 1.mAh is a poor measure of capacity, it doesn't take into account the voltage. Most manufacturers massively overquote the mAh for this reason. You need to use watt hours. 2.For a useful review of a powerbank fullly charge, then fully discharge using a usb power meter and quote the `actual` capacity in Wh. Thanks.

[@oliverbutterfield9844]

If mAh doesn’t take into account voltage, how can manufacturers be over quoting “for that reason”? If I see a power bank for sale with a quoted capacity of 10000mAh, what is being “overquoted” in that case?

[@CarbsAndTurbos]

@@oliverbutterfield9844 Yes it does there are free calculators online on how to workout it out. To find the Wh use (mAh)*(V)/1000 = (Wh) and to find the mAh use (Wh)*1000/(V) =(mAh).

[@STORMFIRE07]

@@oliverbutterfield9844 the “quoted capacity” is usually measured at lithium ion battery nominal voltage (aka 3.7) or 3.3V, whereas almost all USB devices require 5V, so a 10,000 mAh powerbank measured at 3.3V would only have capacity of 6,600 mAh at 5V (and both are equal to 33Wh)

[@jonipoimaa4967]

​@@oliverbutterfield9844 Let's say you have two batteries, one is 3V 20000mAh, another one is 1.5V 40000mAh, if you calculate the watt hours by multiplying voltage with amp hours you end up with the same number. It wouldn't exactly be false advertising if the seller said the battery has 40000mAh, while the competitor had just 20000mAh, but since the watt hours are the same you end up with similar capacity. For example you drain a 1Ah battery at 1A it will last an hour if the voltage is the same. You drain 1Wh battery at 1W it will last an hour no matter the voltage. Theoretically.

[@oliverbutterfield9844]

@@jonipoimaa4967 sure, if one manufacturer sneakily provided you with a massive NiMH cell at 1.2v, I guess that would be disingenuous, but I’ve never seen that. Aren’t they all basically 3.6/3.7v lithium batteries?

[@iam.jasonhoward]

I have a similar battery bank from Anker. These power banks are clutch.

[@STORMFIRE07]

Hi Mr.Lee, thanks for looking into that powerbank, btw do you know whether “pass-through charging” (i.e you charge the powerbank from wall outlet, and the powerbank charges the device connected to it, like a UPS) work on that ugreen powerbank?

[@leepspvideo]

@@STORMFIRE07 I just tried it on my MacBook with a Raspberry Pi power supply. The power bank was charging at 25.1w MacBook was charging at 29.2w from the power bank

[@STORMFIRE07]

@@leepspvideo interesting, thanks a lot for information Mr.Lee, could you also please check whether the powerbank takes any “switching time” (i.e powerbank stops supplying power to devices when it’s connected to wall outlet or disconnected) if it doesn’t do that and supplies power uninterrupted, this could very well be a great alternative to raspberry pi UPS hats, as most of them don’t fit the regular cases, plus they are custom made mostly for pi, whereas this could be a general purpose UPS for all mobile devices

0:30 It's wrong you can take battery capacity lower than 27,027mAh (100 watt-hours) can be legally and safely taken on a flight.

[@leepspvideo]

Many guides online quote 20,000. Not all airlines are the same. I saw some with higher allowances when I was searching.

[@CarbsAndTurbos]

@@leepspvideo I’m saying that 27,000 mah in the same as 100wh. Not 20,000 mah

@@CarbsAndTurbos no, you are saying that now, your original message was a complaint, not a serach for clarification so others can learn again, most airlines will complain about powerbanks over 20000 mah, the 130w is not mentioned almost never in airlines, the mah is.

@@nzavon seems to power everything I have tried. Pi4 should give a longer usage

[@dadawoodslife]

Can you change it and power things at the same time, effectively using it as a ups?

[@leepspvideo]

@@dadawoodslife yes tried it yesterday with my MacBook after another comment

[@jefftysoutube]

The promotional material shows an input charge of 65w through the C1 port. As this is also the only input port the other ports C2 and A are the only ports that can be used for output while C1 is being used for input thus for UPS useage the power output is thus limited to C2:30w A:22.5w. This is from the seller's photos and leap's confirmation.

[@jefftysoutube]

Wow!! kzbin.infoz81r_7oerwQ Explains why the manufacturer refrained from actually stating passthrough/UPS capability!

[@terrydaktyllus1320]

That's not the definition of what a UPS is anyway. A UPS provides power smoothing when mains power is active, and provides a degree of battery backup when mains power is not present - that could mean just providing battery power long enough for systems to gracefully shut down, or it might be racks of batteries (or local generators) providing backup power for an agreed number of hours.

[@NicoDsSBCs]

Hi. I love power banks. This one is way too big for my use for only being 20 000mAh. The mAh doesn't say much. It's Watt hour (Wh) you need to know. You may have 100Wh on a plane. What is about 27 000mAh. mAh is at a certain voltage and without that info you're nothing with mAh. They use the voltage of the batteries and not output voltage of the power bank. Some are 3.2V to 3.7V. All depending on the power bank. It should have a note with the correct Wh. It is impressive it can deliver so much power. But luckily my SBCs don't consume that much. And my PineBookPro neither. My favorite power banks are Veektomx. They deliver what is promised and evern a bit more. And they have the smallest lightest 10 000mAh power banks I know that still charge with q.c. at 18W. Great combo with my qc solar panel. It's charges in about 3 to 4 hours. I wouldn't mind testing this one from UGreen. Got the Khadas Mind now, would be cool to use it with power bank. Cheers, NicoD.

[@terrydaktyllus1320]

One of the nice things about working for as long as I have as a techie in the telecoms/IT/cyber-security industry is that I've seen more than enough international hotel rooms in my my time to not want to see any more, which the modern day prevalence of remote access systems (to my customers' servers) allows me to benefit from, and the fact that I have learned to enjoy vacationing in my own country since a lot of my own countryfolk were radicalised into voting to make themselves poorer and impose economic and travel sanctions on themselves (and me) back in 2016 means that these days I rarely venture into airports just to be pushed around by officious "notzis" in uniforms telling me to go here, not put my bags there, or checking the size of my powerpacks anyway. So, no, I shall pass on this one, due to lack of necessity.
