Multi-Slot USB 18650 Battery Charger for Lithium Cells

Set up a USB charging place for compatible rechargeable 18650 lithium cells. This charger comes in one-, two- and four-slot versions. It is for users matching a charger to cells intended for 4.2V charging.

• ✅ Charge the quantity you use — choose one, two or four slots.
• ✅ Check progress at a glance — red and green indicators show charging status.
• ✅ Use an existing power point — the charger connects to a suitable USB supply.

Choose the Slots Around Your Rechargeable Cells

Check cell chemistry, size and charging voltage before inserting batteries. The 18650 shape alone does not establish compatibility with every cell in that format.

Choose the slot count around the cells you normally use and follow the charger's instructions for charging and supervision. Batteries are not included, and a wall adapter is not confirmed with the charger.
