A portable charger for a Li-ion cell

The UI1 prioritizes simplicity and mobility with a single bay and USB power. It suits a single-battery mod, an occasional vaper, or a backup solution kept at the office. Its indicator helps you track progress without a complex screen. Before each charge, make sure the cell is one of the supported sizes and that it sits properly against the contacts. Once the cycle is complete, unplug the charger if you store it and place the battery in an insulating case rather than in a pocket or unprotected bag.
