Cut it in half and give one half to a friend or the wife :smile:

£69.99?! Get lost, Amazon :laughing:

Actually it's 4.2v for the individual cells as they're Panasonic 18650bs, but they're in a set of series and parallel bringing it up to at least 8.4v (they may use higher to cover QC). They'll then use a buck convertor to get the right voltage.

If they calculate Wh using the individual cell voltage it's 84Wh, if they use the true voltage of the cells it's at least 168Wh.

The marketing thing is a bit bs, as 20Ah is ~17Ah at 5v.

I think it is industry practice to consider the capacity in terms of the 3.7V cells rather than the 5V output, classical marketing "overstatement"

In the cabin, only in device batteries are allowed in the hold.


It's a difficult one, because you don't know what voltage they'd use to calculate the Wh. Potentially it could be more than 100Wh.

Just a quick note - if it's exactly 20000mAh you can take it on a plane. 1 mAh more and it may be too large a capacity for airlines, e.g. First Choice.

I ordered on prime day 20100 22.99 should come today

They are not allowed in hold. Only in hand luggage.

Cancelled my order and will be looking for something smaller around 10000

Not entirely true

British Airways do allow Power Banks up to a certain capacity

Is the 10000mah / 13000mah one the most you can stuff into the jacket without it weighing you down?

Completely banned to put l-ion in the hold.

Expired or price gone up

You are talking about cabin luggage right? Is there any issue with putting it in the hold luggage?

not got a link i'm afraid, in my case I contacted first choice directly who confirmed to me that 20aH is the maximum allowed powerbank. Could be different for different airlines perhaps.

I have replaced my order of the 20100 with this one. Thanks OP.

Bought one, thanks

Voted hot

Is that RRP another amazon joke is or is it a genuine saving??

That's not coming up as a hyperlink and the app won't let me copy it for some reason

Is this better than the 20100 that was on offer on Prime day? I got that one no rush so a few days until it is delivered, wondering if this is better and to cancel the original? Anyone know pluses and minus of both of them?

You can Prime day is over.... price creep on Amazon is on the upward slope :wink:

I'm looking for something smaller, around 10000, any suggestions?

What is the advantage of having a powerbank specifically with a USB C port

Thank you, have been waiting for a deal on an external charger / power bank
