Terrible teardown on Big Clive's channel on YouTube

Indeed fire and injury is (relatively) unlikely but venting, swelling or just plain old poor performance is very likely indeed. And most of us aren't going to be paying a solicitor to handle getting our pound back, tempting as it might be!

Besides, don't forget this is the company that still proudly states "Everything's £1" on their windows/signage when they've already been done for it by advertising standards agency over a year ago...

Yeah these are rubbish, mine were about 200mAh if that.

If you can get a FINDLA from your local IKEA (Wednesbury has loads for £4.50 even though they're not on the website) they give a real world capacity of 3200 mAh (tested by myself) and are very slim and deliver an amp constantly. Nice.

Cracked open to check the cell voltage on both and came out at 0.03 volts, won't bother charging as there's a good chance they'll go all wibbly!

Because a sample size of 2 is a big enough sam

The circuitry is generally excellent with components that even the big name brands use even on these cheap power banks, it's the dodgy cheap batteries you have to watch out for and where they scrimp on money to hit a price

The best thing to do is do a full charge then drain it to see if the battery actually works. This means that if it fails you can get a replacement or refund

I know this won't be popular on a site dedicated to bargains, but batteries are one area I usually find buying better quality is a good idea (like bin bags and toilet roll). I grabbed an Anker 10,000 mah pack a while back for about £10, it will charge my phone at least twice from dead, it's also lasted well and I know Anker's support and replacement policy is superb. Charging a device that costs hundreds with something that costs £1 and has a 25% failure rate as mentioned above doesn't strike me as a great idea.

Bought another two of these recently, for a pound each they are a cheap solution if you get caught out with a dead phone and you really need to make a call or two.

I bought 8 for the battery's inside (couldn't wait for battery's to arrive from China!) two had failed, so more likely a 25% failure rate

save your pound these are beyond useless

Please don't buy unless you intend to set fire to your house with it whilst you're asleep charging it, total cheap s**t deathtrap.

Some people would still buy this if it had 100 mAh stamped on

Have to be honest and say I'd never have any cheap battery tech in the house, it's just not worth the risk for the sake of a few ££...

I've bought a few of these, two from Poundland and two from Poundworld. After a few charge/discharge cycles the Poundworld banks come off better, both taking 1000mAh+ charge where as the Poundland examples only take 600-800mAa, they also seem to discharge quicker under higher loads - handy for running led's but useless for charging a phone.

Do not leave these plugged in overnight ! These are the same ones Poundworld were selling last summer.....

Dangerous.....

Personally I wouldn't trust any of these cheap chargers that use 18650 (lithium ion) batteries. Cheap circuitry inside could cause over charging of the battery (power bank battery) and when these batteries fail they fail badly

I have an outside "Open Sign" for business with 2ft of flashing led lights, powered by
one of these.Did 5 hours today, before I brought it in, think power bank was low since red light on in charging port.
Pretty good I thought!

These are great for a quick boost but be warned any external battery capacity is not what it states. 1200mah is about 800mAh normally about 2/3 of what it states this is due to how electronics work and factors like heat loss.

Those people regularly needing to top-up would probably be better served by a much higher capacity product. I wouldn't say that this particular product is aimed at them. Horses for courses, as previously remarked.

Not saying it won't serve a purpose but for those who regularly need a top-up there are far better (and probably safer) products for just the cost of a pint of beer more than this.

Seems these aren't very well made and add very little charge. For £5-£10 you can get something far more useful on Amazon - that won't end up sat in a drawer once you realise you can't be bothered to charge this. This is classic drawer-fodder - just like the Bluetooth telephone receiver I picked up from Poundworld

I got about 25% charge from it so not too shabby for a £1 item, good for emergency boost.

Quite happy with mine that I bought a couple of weeks ago. Very handy as an emergency top-up and small and light enough to carry around without inconvenience. Cost: £1. What's not to like?

I've got one - it approx 1/2 charges my Motorola MotoG 3G. It is very small and handy for a quick booster charge (but unlikely to fully charge any smartphone). Charge cable as some mentioned ONLY charges, won't work as sync cable - so that's not a bonus (but I use a short old Nokia one, in case I need to sync when I'm out and about).
Hope this helps someone!

Avoid

i got a couple of these and pulled it apart to use the battery when i got a torch delivered from ebay and found it used a 18650 battery and had no adapter that would fit. you can get the batteries as low as 2 for 99p on ebay from malaysia but i would have had to wait 2 or 3 weeks

it's a bargain for a pound

they also had 2 metre iphone and android cables. the IOS ones state they only charge with an adapter not PC but i've been using both types (iphone 6s and ipad3) to sync and they work fine. the extra length compared to the standard cables is handy if you are plugging into the back of a desktop

good find and excellent price. Although 1200mah will be about 1/3 of a Samsung S7 etc
