Small, light, easy, cheap and above all safe!

"The most compact, smartest and most universal charger for Li-ion".
Compact it's really, hinrechend "intelligent" well - it adheres to the guidelines of the battery manufacturer - it is not only universal. It is optimal for batteries between 700mAh and 1000mAh. Smaller must then already be explicitly authorized for high charge currents, with larger one introduced in accordance with a lot of patience and the turn-off at the end of the constant voltage charging phase is too small, this phase is unnecessarily protracted.

In return, the unit stops at the manufacturer's specifications, under 2.9V tried the battery with a reduced charging current of 70mA again "prop up", from 2.9V is loaded with constant 500mA to 4.2V when using the voltage limitation and the constant voltage charging phase begins. This ends when the current consumption of the battery drops below 50mA. If the battery after the unit he is with negligible current of a few uA further charged (probably for technical reasons, which is the current is not completely out, but many other devices as load with much more power on - what they really should not). Remains of the battery in the device when it is not connected to a power supply, so it is with negligible 25uA discharged (many other appliances draw as far more power, in some cases several mA), you can the battery so can easily slightly longer in the charger.

I've been looking for the 18350 800mAh battery a flashlight a possible small and inexpensive but nevertheless reliable charger, and found in MC1 exactly. Important to me was also USB as a power source, as appropriate mobile power supplies available and traveling are also included. So I save money, space and weight. But I refrain on voltage, current and capacity display.

Who has only just time to load a smaller round cell can go wrong with the appliance nothing.

PS: In the meantime I have two MC1 and MC2 times the big brother (in principle two MC1 in a casing) and so far all work fine.
