Description
The Universal Dual-Slot Li-ion Battery Charger is a compact charger for compatible 3.7V nominal rechargeable lithium-ion batteries. It is primarily listed for 18650 cells and may support other cylindrical battery sizes, including 14500, 16340, 10440, and 26650, depending on the cell dimensions and charger contact arrangement.
The charger has two slots, allowing it to accommodate up to two compatible batteries at a time. Its LED indicators help you monitor charging: the listing states that the light is red while charging and turns green when charging is complete. The charger is also listed with automatic charging termination and several protection features.
With a 100–240V AC input, 4.2V output, and a listed 1A output current, this charger is intended for compatible single-cell lithium-ion batteries. Confirm whether the 1A rating applies to each slot or to the charger as a whole before charging two cells simultaneously.
Key Features
- Dual charging slots: Holds up to two compatible cylindrical batteries.
- 4.2V charging output: For supported single-cell lithium-ion batteries with a matching charge specification.
- Listed 1A output current: Confirm the current available per slot.
- Wide AC input range: 100–240V AC input, as specified.
- LED charging indicators: Red indicates charging; green indicates charging complete, according to the listing.
- Automatic charging termination: Listed to stop charging when complete.
- Compact construction: Metal and plastic materials with a black finish.
- Portable size: Suitable for a home electronics bench or workshop.

Compatibility note: The listing’s headline mentions 3.7V batteries, while the charger output is specified as 4.2V. These values are normally consistent for compatible single-cell lithium-ion batteries: 3.7V is the nominal cell voltage and 4.2V is a typical full-charge voltage. Always confirm the exact cell chemistry and maximum charge voltage before charging.
Applications
- Charging compatible 18650 lithium-ion cells
