Review on SMAKN Lithium Battery Charging Charger by Adam Rossi
it's a bit slow but it works.
This device charges a single lithium-ion battery, but it charges much slower than 1 amp. My built-in small ammeter shows about 125 milliamps per hour input current at 4.2 volts. This means that it takes 9-10 hours to increase the voltage of a 18650-2200mAh battery from 3.6 volts to 4.2 volts. that's about three times longer than the cheapest standalone charger on the market. I wouldn't even try to charge the battery or a battery with a higher mAh capacity. I would buy a pre-assembled charger before buying again. it works, but slowly, slowly, slowly.
