SC1 is a compact universal USB charger designed for 3.6/3.7V Li-ion batteries with length 54 - 75 millimeters, so it fits also Li-ion batteries type 20700 and 21700 with protective electronics. When powered by a sufficiently strong USB power supply, it can charge up to 2000 mA. Thanks to the movable minus contact, it is therefore suitable for all larger Li-ion batteries type 18650, 18700, 20700, 21700, 22650, 25500 and 26650. Its minimal size and weight make it particularly suitable for travel.

Charging Li-ion batteries
Use the included USB cable to plug the charger into a computer, a USB mains adapter or USB car adapter. A standard mobile phone charger with a micro-USB connector or power bank can also be used to provide power.
Insert the discharged battery, the indicator LEDs will flash during charging to show the charging progress, and light up when fully charged. When the battery is inserted the other way round, all the indicator LEDs start flashing.
Warning
- Do not charge Li-ion cells that have undergone a state of excessive discharge (below 2 V).
- Do not insert batteries into the charger in reverse (reverse polarity).
- When using the charger, please observe safety guidelines.
- We recommend using high quality protected Li-ion batteries.
- Not intended for charging LiFePO4 batteries.
