I once paid more than this for a takeaway curry and it didn't last a day.

So you'd prefer to pay a tenner for the same thing?
These are cheap because the same technology (maybe even the same circuit?) is used in every LED lightbulb. They are produced by the million every day and therefore cost pennies to make.

Good for an emergency. Fairly useless once you get home. In the long-run you're better off buying something for £10-£15 that will have a higher capacity and be useful for commutes and suchlike.

Thanks OP, perfect companion for my Xiaomi USB light for camping.
As noted, these are cheap, use common sense when charging - don't leave them charging on a flammable surface (applies to any other device when on charge). :)

The instructions actually say not to charge overnight or whilst you are out of the house.

I got one of these a while back, it didn't charge my phone for very long. The ones that they sometimes have in poundworld are much better, I've been using it for a while now and it charges my phone quickly usually to about 80%.

Any reason why you would leave this charging at home and walk off? Given it's a thing you're supposed to take with you. And given the low power density I doubt it could do much. I'm surprised it hasn't been compared to the Note 7 yet, as that's usually guaranteed hilarity.

OK, i want to say something about these chargers....

I am not here to **** off the efforts of the OP, just maybe shed some light on battery safety.

I use this size of battery cell in my e-cigs and they can be great cells, tesla cars use them in huge quantities inbtheir elecrtic cars.... however china has a bit of a reputation for fake / poor quality batterys, god knows where the 18650's in these chargers have been sourced.

To give you guys an idea of what cheap Chinese craftsmanship looks like check out this image!

If you guys still want to buy these things, then that's up to yourselves, please if you have children or pets maybe reconsider or treat with extreme care!!!

If one of these things goes pop due to lack of circuit protection or bad cells it could get messy.
#15
One other thing, for me the fact these things are rated @ 1200mah that sets off alarm bells with me, even a super cheap 18650 battery should have about double that capacity at least. Even a cheap own brand supermarket AA battery will have double this capacity.

I come from a family of male techies so I like watching these videos - even if I don't understand it all. I agree, though, his voice is wonderfully soothing. Sometimes I put his videos on in the background on my tablet and nod off (hardly a glowing advertisement for his videos, but I do genuinely think they're interesting as well!).

ibaisaic's videos are good for the same purpose - nerdy waffle about gadgets (vacuum cleaners) but he also has a hypnotic voice.

Worth it just for the boost converter and charging circuit to use in your own projects. I've got loads of laptop and phone batteries repurposed that way and they all look like terrorist devices.

Typical alkaline batteries have 2,500mAh at 1.5 volts -> 3.75 Watt hours. The battery in this is 1,200mAh at 3.7 volts -> 4.44 Watt hours.

Lol that is if you believe the capacity of the battrry inside this charger.to be true! :p

Moving the goalposts- first you say the marking is too low, then you say you don't believe the capacity is as high as it is marked. Why can't it just be an honestly marked low capacity battery?

My research on Amazon: This exact item, but without any battery inside, costs at least £1.20 sent from China. Lots of cheap, high capacity marked, batteries have reviews that say they are only about 1200mAh under test, but none of them cost less than a pound each. Respected brands cost several times more.

Rather than speculate, I am conducting a charge/recharge cycle on this item. If it is under the stated capacity, it should charge fully from discharged in less than an hour and a half.

There is that, however I find it sluggish to always carry around my 20,000MAH battery pack. I need a bag for it. Fitting it in my pocket is possible however it adds a lot of bulk. Having a few of these a day would be brilliant.

I compromise with two - I have a 5,000mAh Anker one that was £5 and is barely any bigger than this, and a 10,000mAh Aukey one. If it's just for work I take the Anker, if I'm going away I take both.

No, not moving the goal posts at all... The 1200mAh rating is too low for a 18650 cell, and the capacity of these battery's is most likely also a load of rubbish. Well just look at the above you tube link for example, one DOA and one with only a couple of hundred mAh. Sounds like recycled battery's to me.

Do me a favour mate, can you list me some reputable company's that make 1200mAh 18650's??

It is well documented that cheap battery's from china are coming from less than reputable sources, i certainly would not trust them.

Recycled "Grade C" 18650 batteries from china

Wouldn't ever bother with these as risky on quality and wouldn't charge most peoples phones. Makes it fairly useless in my opinion. I bought some 10000 mah Xiaomi ones for around 5-6 quid which aren't much bigger than this. Current generation stuff gone a lot smaller as I have the old ones too and they are bulky.

Each to their own though so if someone feels this meets their needs then fair enough.

You are still working on supposition. I am running a test (it is taking awhile to discharge the item) The marked capacity is certainly not in the same range as the fakes. I don't see why a faker would mark a low capacity in the first place. Nor, as the battery is not visible to the buyer, do I see why anyone would bother to conceal a smaller battery core within a 18650 case, as they seem to have done with the Ultrafire in your illustration.

I made no such representation. I said that respected brands cost lots more than those with false high ratings. That would be respected brands with high ratings that are not false. I have, however, seen Sony and Samsung stamped with ratings of 2400 mAh. So, if this one was marked 2400mAh, would your suspicions be allayed? Or would you still be claiming fakery, when you don't even have the item to try for yourself?

I have finally got the item fully discharged and have started recharging it against a stopwatch using a proper Samsung phone charger rated at 0.7 amps output. This is the closest charger I have to the item's stated maximum charge rate of 0.8 amps, and should take about 1.7 hours (1 hour 43 minutes) to charge the item to 1200 mAh.

Edit- one hour mark and still charging.
Edit- one hour 54 minutes and still charging.
Edit- two hours 15 minutes and the light has stopped flashing, item is fully charged. The extra time may not mean anything, perhaps just inefficiency or the Samsung charger not quite delivering 0.7 amps, but I think the test easily shows the battery is not short of its stated capacity. Interpreting the result strictly would indicate that the battery has greater capacity than marked (0.7 amps times 2 and a quarter hours equals 1575 mAh).

Sadly they changed the design of these and they now come with the battery soldered. I was using the older ones as chargers as the 18650 was removable!

I don't believe an item has to be on a reduction to be a deal. This item has in fact been posted before, months ago and more than once, at this price, and it has always gone hot. It is cheaper at Poundland than almost identical items elsewhere, as I have already noted. However, I recommend that you do not buy one, as I sense that you would inevitably be dissatisfied with it, since it does not bear a sticker saying reduced from £2.99 RRP.

If you want the version with no battery installed, they are available on Amazon for £1.20 delivered from China.

I've taken a few apart and charge the batteries separately and they are 1150-1250 so right in the ballpark they say. I only wanted the converter 3.7 to usb to add to an old note 10.1 battery I have laying around.
#33
These are practically useless. Take forever to charge and at 1200mAH, wouldn't even charge 30% of my phone.

COLD.
#34
Tested these myself, they're actually about 300mah... Not worth their weight in manure
#35
The fact we are seeing some of these things at 300mAh or worse, DOA really suggests they are cheap knock off recycled battery's! :(
#36
got one, had a play with it....
cuts power at around 3v of the battery and charges up to 4.2, it took just over 800mA to charge from 'dead' to 'full', taking into account the dc/dc conversion up to 5v it should be 700ish mah
Ended up putting a 2200mAH battery into it and works fine as a backup emergency to charge my S5 battery 60-70%
