Description
The XTAR MC4S charges up to four batteries simultaneously via its independent 4-slot design, automatically selecting the most efficient current (0.5A or 1.0A) for each slot. It accepts a wide range of Li-ion cylindrical formats — 10440 through 26650 — plus Ni-MH and Ni-CD cells from AAAA to C size.
Power is supplied through a Type-C input (DC 5V 2.1A), making it easy to use with standard phone chargers and power banks. Seven built-in protection functions and 0ΔV / -ΔV smart charging extend battery life and ensure safe operation.
Key Features
- 4 independent charging slots with mixed chemistry and size support
- Type-C power input (DC 5V 2.1A) — compatible with standard USB-C adapters
- Automatic current distribution: 1A × 2 slots or 0.5A × 4 slots
- 0ΔV and -ΔV smart charging algorithms to maximise and protect battery life
- Seven protection functions for safe charging
- LED indicators show charging status for each slot at a glance
- Accepts two 26650 batteries in slots CH1 and CH4 plus two unprotected 21700 in CH2 and CH3
Product Benefits
- Mixed charging means different battery types and sizes can be charged in the same session
- Current-adaptive circuitry selects the highest safe current per slot, reducing total charge time
- Type-C input lets you charge from a laptop, power bank, or car charger without a proprietary adapter
- Smart algorithms prevent overcharge, over-discharge, and short circuit damage
- LED status display removes guesswork — each slot shows its charge state independently
