Liitokala Lii-100 is the most versatile compact USB charger on the market. It supports Li-ion, LiFePO4 and NiMH batteries of all common sizes and charging voltages. It even supports high voltage Li-ion batteries with a charging voltage of 4.35V. The movable negative contact allows charging batteries with a length of 33 - 70 millimeters. The charger can therefore be used with, for example, classic AA, AAA and Li-ion batteries type 10440, 14500, 14650, RCR123A / 16340, 17500, 17670, 18350, 18500, 18650, 18700, 22650, 25500, 26650 and 32650. Charging current can be selected from two levels - 500 and 1000 mA.
When inserting a charged Li-ion battery, the charger can also be used in reverse, as a backup source (power bank) for charging USB devices (mobile phones, MP3 players and more). You can read a detailed English review of the charger here.
The power cord plugs into the charger via a micro USB connector, so it can be plugged not only into a computer's USB port, but also into many mobile phone chargers. If you don't need to charge multiple batteries at once and appreciate maximum versatility, then this is an excellent choice.

Using the charger
Connect the cable to the micro-USB connector and insert the discharged battery. The charger detects NiMH/NiCd and regular Li-ion batteries automatically, other types must be selected within five seconds of inserting the battery manually with short button presses:
- To charge LiFePO4 batteries, select "Li-Fe 3.2V"
- For high voltage batteries with charging voltage of 4.35V select "Li-ion 3.85V"
The charging current of 500 and 1000 mA can be changed by long pressing the button for 2 seconds.
The four indicator LEDs light up gradually during charging, and all remain lit after charging is complete.
USB output - insert a charged Li-ion battery into the charger and connect the USB device to the classic USB connector. In this mode, the charger has protection against too deep battery discharge and automatically disconnects the USB output when the battery voltage drops below 3V. The maximum output current is about 1.3 A.
Warning
- When using the charger, please observe the safety guidelines.
