If you're after something which store a lot of power then this is for you. If you need one for casual use then you can pick up one that is 10000 mAh for £20. That said, 10000 is pretty good!

£35 on an unbranded battery? To be fair, I would rather go with an Anker for that price.

I cant imagine it being that great to carry, one for the back pack thats for sure.

I bought the 10k mAh for £18 and its bloody brilliant, keep it in my car and used it umpteen times!

I've ordered mine! Can't really go wrong with 22400mAh @ that price



Hahah! except you won't be getting anywhere near 22400mAh, you'll get one of these DIY boxes:

ebay.co.uk/itm…970

Note the supplied "20,000mAh" sticker, with an empty box:

.. and 6 UltraFire recycled batteries in it like this:

I can't find any trace of a manufacturer called "EC Tech" (Not EC Technology), only a poor quality PDF instruction manual with their email on. Would I trust a company with an email address of ectechnology001@gmail.com ? Hmmm now let me think.

Wow! If true, that's **** poor!

I recall speaking with someone in a warehouse, the company they work for sell laptop chargers and there were plenty of stickers on a table next to them, which you'd find on the back of laptop chargers.

There is a review here
Plus there is 93 customer reviews on amazon.co.uk.

Yep, it's only £36 wasted, but don't feel bad, you've kept a whole family in food and rice for the next two months.

lool

6*18650 battery=20000mAh? I don't think so.
The capacity of one 18650 li-ion battery could be 2200, 2600, 2800, 3000, 3200. 20000/6=3333.3333, while there is no 3333mAh battery at 18650 size .
I have disassembled the 22400mAh power bank, and found that it is using 8*18650 battery. 22400/8=2800. Each battery is 2800mAh.

The PCB is great as the parts are in alignment.
