Vapcell Q8 8-Bay 18650/21700 Li-ion Cell Charger

The Vapcell Q8 charges up to eight 3.6/3.7 V Li-ion cells at once, each in its own independent bay, so a full set of 18650 or 21700 cells for a DIY Li-ion pack, radio or torch can be topped up in one go. It runs directly from AC mains.

Key features

• Eight independent bays: 1 A per bay (8 A total), so cells of different sizes and charge states can charge side by side.
• Li-ion termination: 4.2 V +/-1% cut-off for standard 3.6/3.7 V cells.
• Wide size range: takes cells 10-26 mm in diameter and 34-72 mm long.

Specifications

• Bays: 8
• Output: DC 4.2 V +/-1%, 1 A per bay, 8 A total
• Input: AC 100-240 V, 40 W max
• Cell dimensions: 10-26 mm diameter, 34-72 mm length
• Supported sizes: 10440, 14500, 14650, 16340, 18350, 18500, 18650, 20700, 21700, 26500, 26650

It charges standard 4.2 V Li-ion cells only, not LiFePO4 cells (3.65 V full charge), NiMH cells or LiPo packs; charge assembled packs on a balance charger. At 1 A per bay, a 5000 mAh 21700 cell needs roughly five hours or more from empty.
