just because it says 20000mAh doesn't mean it will actually be 20000mAh

adamspencer95

just because it says 20000mAh doesn't mean it will actually be 20000mAh


Is there a way to check what the true capacity is?

You are correct - this manufacturer has been the main one selling the 25600mah version that was generally sold for the cheapest online with multiple posts on here:

You can gauge on the weight and dimensions if there is enough space and weight to occupy enough rechargeable older style cells.

An Anker 20100mah unit weighs 350g, whilst this is 340g

​unless you have a capacity tester, unlikely.

you can always guestimate based on what you can charge before it runs out of juice if you know the capacity of what you charge (minus ~15% losses) eg you should be able to charge a 3000mAh battery (oneplus 3, s7, s6 edge+) 5-6 times (15000-18000mAh) before the battery pack dies

Lol this question always gets asked! Has it got the quick charge function on it?

Not at this price lol, no quick charging for output or input. Although 2.4amp to any device will be quick.

Will test when mine arrives, I mean even if it's half what it says, it's still a decent price for 10k MaH... will try to remember to post after receiving

decent find heat added

Heat added and ordered one as well

11 hours full charge time? Is that the norm lol

I have 2 x 15000mah batteries that too have input rated @ 2.0amps and they take about 8hrs roughly so yep...

11 hours full charge time? Is that the norm lol



I have the Anker 21000mah pack and it takes a very long while to fully charge, we're talking 12ish+ hours....

I've got this exact one and can highly recommend it paid full price and would again been using it most days for a year now to top up my phone at work and charge it up fully once a month

This probably is 20000mah, Swees are one of the better one but if you're that worried you can just buy Anker.

11 hours full charge time? Is that the norm lol


No , my duel port powerbank takes 12-13 hours so it's an overnight charge

This is very cheap, I've just bought the 26000 for £21

It is 9.99 w/o prime.

FWIW I bought a Swees Li-Po 8400mAh battery about 4 Christmas' back and it's still being used today - use it at least twice a week. No issues. Ironically it cost £8.99.

Will buy this one.

Won't post to Northern Ireland. Daft.

Think you are wrong? Adds £3.99 for postage to my order (not Prime)

Another one in desk drawer , ordered , thx , voted hot!

Thanks ordered

Can someone who has one please confirm that the capacity of 20000 is marked on the device? If it isn't then it is likely to get confiscated if you try to take it on a flight.

This won't have 20,000mAh... Just buy a lower rated one from a reputable company for the same price.

I've taken various large batteries on many flights and not once have they checked the capacity.

Keep in mind that these all use 3.7v cells, it has to be inverted to 5v which won't be completely efficient. Also charging isn't completely efficient. Gonna be like that with all power banks. Realistically it should charge a phone with a 3aH battery 3 or so times, maybe more.

As in the item is £9.99 to purchase (before delivery) without Prime, but Hotukdeals and camelcamelcamel have it down as £14.99 by default when it isn't - error somewhere on Amazon's part:

Look at Bigclive's review of a lethal Swees USB multi charger and see if you really want their products in your house...

Hard to find but here it is here: https://www.youtube.com/watch?v=3Hdn0MuCK_0

Like Bigclive, I thought the above brand was Sweex at first!

Original Poster

Just received 2 units and they are fairly hefty.

Going by the location of the usb ports on the side there would have to be the circuity directly behind.

That would lead me to thinking only 2 cells sit side by side and that only 6 cells could fit. 6 x 3350 = 20100mah.

Has anyone received theirs and tested using a capacity tester?

I have mine, testing it now with my iPhone 7, as a answer to a question above, it states 20000mAh on the back....

So far I've charged my iPhone 7 from 36% too 93% with 4 lights still remaining... (57% in around a hour, with atleast 30-40minutes Being used so will charge a lot faster without useage)(also bare in mind it came with 4 lights on but doesn't mean it was 100% charged)

Will keep updated as my phone dies and recharging

Well, Samsung's batteries overheated - in this case it's a dodgy transformer that makes the USB port go Live (very, very dangerous).

In his blurb he says "Although I've come across some really dodgy power supplies with poor insulation between the mains and low voltage sides, this is the first one where the USB ports have carried full mains current. (via a rectifier)".

You're comparing oranges and apples.

​Fair point. I'm just saying let's not malign a product unfairly.

Well I had to halt my testing due to a thieving girlfriend who stole it to charge her phone X) however I'm very sure it's 20000Mah as it's still holding strong after a good few hours useage now....

Would recommend at this price, at full price I would maybe stick with anker for the name for not much more money....

My thoughts exactly re the pricing. The item is OOS on Amazon now, when it comes back in stock I have a funny feeling it will come back at £15 or £20 and that this batch was a pricing mistake for Amazon...
