Review: USB connection has been strengthened - I bought my first one of these 2 years ago, and recently the USB socket became loose and intermittent. I looked inside and saw the small socket had become detached from the printed circuit board. Nevertheless I like the small size of this charger so I bought another one. This time I opened it to see if I could put some glue in to strengthen the socket (don't do this yourself unless you know exactly what you are doing, and also any warranty may be void). I found the printed circuit has been modified and the USB connector is mounted much more securely. This is a great little charger that fits nicely in my camera bag.
Review: Runs from USB output, so no chance of Overcharge. - A brilliant piece of kit that operates from USB power supplies and can charge AA/AAA Batteries without frying them; the USB supplies I use are all regulated to 5 volts, so no chance of overcharge as can happen with many chargers. Could work from a power supply pack, but I would recommend that a power pack should be rated at around 25000mAh otherwise the pack would run out of power before fully depleted AA batteries were fully charged. Can be used with a computer/Laptop USB output, particularly more modern machines.

### ⭐⭐⭐⭐⭐ USB connection has been strengthened
*by D***T on 16 June 2021*

### ⭐⭐⭐⭐⭐ Runs from USB output, so no chance of Overcharge.
*by M***S on 24 August 2020*

A brilliant piece of kit that operates from USB power supplies and can charge AA/AAA Batteries without frying them; the USB supplies I use are all regulated to 5 volts, so no chance of overcharge as can happen with many chargers. Could work from a power supply pack, but I would recommend that a power pack should be rated at around 25000mAh otherwise the pack would run out of power before fully depleted AA batteries were fully charged. Can be used with a computer/Laptop USB output, particularly more modern machines.

### ⭐⭐⭐⭐ Inefficient But Still Pretty Handy To Have
*by N***A on 26 January 2019*

The specifications are a little misleading in that it doesn't draw anything close to 2A from the USB supply: but then you wouldn't expect it to since the output to the batteries is only 1.2V rather than 5V. So a basic 1A USB supply is all that is needed to achieve the maximum advertised charging speed, in fact. There's nothing to be gained from using a better one. This is a smart charger rather than a fast charger. I haven't measured the output, but assuming it is indeed delivering the claimed 500mA to each AA battery at 1.2V, that would make it about 55% efficient (drawing 4.36W and putting 2.4W into the cells - see picture). Far from great. But I think NiMH charging is generally only about 66% efficient anyway? Certainly, the charger electronics seem to get warmer than the batteries themselves -- but nothing gets actually hot at this charging rate (which is C/4 for 2000mAh capacity batteries). The charger seems to pulse the (input) current down and then back up with increasing frequency as the charge cycle progresses, which one can only hope is the microcontroller doing its thing to try to assess how full the batteries are... Then after the batteries show as fully charged, rather than settling down to a constant trickle charge, the input current seems to be all over the place... Hopefully that is also part of the 'smartness'... although the batteries do, strangely, stay very warm if left in the charger... I haven't done any tests yet to see whether the batteries are truly charged to full capacity, but overall this seems like it may be a useful gadget to have. Just have to bear in mind that, for use on the move, recharging a set of 4 x 2000mAh AA batteries using this charger will take around 5000mAh out of the quoted capacity of a Li-ion USB power bank (17.44Wh at 3.7V plus some conversion losses). Ideal for use with a car cigarette lighter adapter during a 4-hour journey though.
