Its also easy to use. Simply plug in the gold-plated contacts into any USB port and a 3.7V\/4.2V lithium polymer or lithium-ion rechargeable battery into the JST plug on the other end. There are two LEDs - one red and one green. While charging, the red LED is lit. When the battery is fully charged and ready for use, the green LED turns on. Seriously, it could not get more easy.\u003cbr data-mce-fragment=\"1\"\u003e\u003cbr data-mce-fragment=\"1\"\u003eCharging is performed in three stages: first a preconditioning charge, then a constant-current fast charge and finally a constant-voltage trickle charge to keep the battery topped-up.\u003c\/p\u003e\n\u003cp\u003eThe charge current is 100mA by default, so it will work with any size battery and USB port. If you want you can easily change it over to 500mA mode by moving the slide switch (\u003cstrong\u003enew for this V2 version!\u003c\/strong\u003e) on the top over to \"High \/ 500mA\" mode, for when you'll only be charging batteries with 500mAh size or larger.\u003cbr data-mce-fragment=\"1\"\u003e\u003c\/p\u003e\n\u003cul\u003e\n\u003cli\u003eComes assembled and tested with a free bonus JST cable!\u003c\/li\u003e\n\u003cli\u003e5V input via PCB-style USB connector\u003c\/li\u003e\n\u003cli\u003eFor charging single Lithium Ion\/Lithium Polymer 3.7\/4.2v batteries (not for older 3.6\/4.1v cells)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eNEW for V2\u003c\/strong\u003e: 100mA charge current, adjustable to 500mA by flipping a switch, no more soldering a jumper closed\u003c\/li\u003e\n\u003cli\u003eFree 2-pin JST cable included!\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003cp\u003eThe MicroLipo charger can get hot during charging.
