Not a typo. Poundworld have also had a version of these in the past. Clearly you should pay more if you want a sturdier device with a bigger charge but these are cheap enough for a reason.

Perfectly fine for a quick spurt that'll keep your tunes playing long enough to get you home to your big boy charger :smiley:

Amazing price but a battery at that price...



I'd be wary of what happens with some cheap ecigs

Got one yesterday. Charged it, flashes to let you know it's charging, took an hour or so. Tried it on an Acer iconia 7 tablet with 1% left.
Hour later, nothing left in the power bank and 52% power on the tablet.

I'd call that a win, especially for the money. Excellent stocking filler.

Yep and that is all you could need until you get home. Besides its only £1, what is everyone moaning for.

The cable is shocking for use when charging: it has about 1.1 ohms resistance - i.e. if supplying 1 amp then the 5 volts at the battery will have dropped below 4 volts at the connector into the phone (the cable will be losing 20% of the energy passed through as heat) - in practice a phone will usually lower the charging current it draws down to below 0.5A to maintain a decent voltage, i.e. doubling the time to charge.

I have never come across such a poor cable for the length before (in fact the only cable I have with such a high resistance is a poor 2m cable, which is more understandable); I doubt it has any copper in it, more likely wet string.

Use the power bank (it can both take an input current and output a current of a respectable 1 amp) but throw the cable, unless you just use it for data (but it is probably awkwardly short for that) or have a device incapable of fast charging.

It's only a pound and lots of things can be powered from it, may get you out of a jam

Yeah I know :smiley: Not as if I'm making the protection circuitry though and that is the most important part.

If you don't fancy a ready made powerbank lord only knows what disasters await those that make their own! :smile:

After the EE scandal with their power banks I don't think I could trust one of these. However if you are looking for an even more skin-flint way (and possibly even more risky) of getting your hands on a cheap high capacity power bank I would recommend one of these.

You fill it with your own cells (so this is not for everyone) I get mine from old laptop battery packs. One charger tends to last about 2 weeks using on and off when I need it, but with an 8 cells it is a big thing. Just an option for anybody that fancies it.

It's not meant to charge your phone but to give you a bit of operating juice when things look bleak on the power front. I have one and it gives me enough juice for my journey home to be at to text, call or listen to tunes.
Have some heat OP

Likely these are around 65-70% efficient so you can expect around 850mAh of usable capacity. I've considered getting one for when I might need a quick boost of power before but my 2600mAh one cost me £2.50 and isn't much bigger than this - if at all - so I'd just pay the extra to be honest.

I've not used one myself. Just going of figures.

I currently run 2 different 10400mah ones. Roughly £11 for the Xiomi branded and £2.50 reduce to clear one in asda year or so back. No faulting those.

Thats assuming 100% power transfer efficiency and these things are crapi would estimate 10 - 20% at most, not to mention the likly output current is 500Mah to 1A at most which isnt enough to charge a high end smart phone properly. like most things you get what you pay for, this just isnt worth it for a phone. But plenty worth it for so many other applications like usb lights fans.

You are lucky to 80% on the best powerbanks so what you get from a Poundshop is anyones guess! More power in a fart I reckon!

That's what I don't understand with everyone's complaining.

Most people have an iPhone which is sub 2000mah, or the plus models that is sub 3000mah.

My s6 edge standard is 2600mah. Most phones in the past year are creeping up to 3000mah, unless they are a larger screen device being around 3440mah. With the uncommon phones being 4000mah+

People have got to stop acting like 1200mah isn't going to do a thing. It's a good 40-60% charge on most phones out on the market.

OK for a quid if you don't already have one but just bare in mind that you will never get 100% of the rated power on these things so you won't get near to 1200mAh.

One thing these could be good for is powering the USB Xmas lights on sale in £land. I'm using my big unused bank to power the glowing snowman I have :smiley:

You should've seen the post the other week. Someone posted an Anker branded one with roughly the same mAh thinking it was a deal at £12.99.

For £1, this isn't bad, will give most people a good 40% charge if you're on a 3000mah phone.

It's like buying a PAYG mobile phone then topping it up with 20p balance

Posted this a few weeks back http://www.hotukdeals.com/deals/1200mah-usb-power-bank-charger-1-00-poundland-2527499

As someone in that deal pointed out they are 800mAh cells inside, but I think they're useful for a quick top up.

The pack contains a VERY useful 15cm micro USB cable.

Amazing price but a battery at that price...

for 18650 battery, can't go wrong for a pound.

Fair enough, I just wanted to clarify.

My £8, 5 year old 10,000 mAh box is dead (SWMBO broke the USB port somehow), so I am on the lookout for a new one.

The smallest I had seen before now was about 5,000 mAh, not counting a 3,000mAh KFC were giving away for free a while back (not in the UK).

do these work or are they like there power leads charge at about 300mah per hour

Typo, or do they really sell a power bank with a 4th of the capacity of a modern smartphone battery??

My brand new Xiaomi, although to be fair, it is only 4200mAh nominal.

Either way, this is still less than 1/2 the capacity of any phone I know, even the under-batteried iPhones.
