EFEST LUC V8 - Battery Charger 8 Slots

The XTAR MC4S is a smart charger with 4 slots designed to efficiently recharge your batteries used in vaping or other electronic devices. Compact, reliable, and easy to use, it allows charging multiple batteries simultaneously while providing independent monitoring of each slot for maximum safety.

🔋 Simultaneous charging of up to 4 batteries
The MC4S charger can hold up to four rechargeable batteries at the same time. Each slot operates independently, meaning the batteries can be charged separately without interfering with each other.
The charging current automatically adjusts based on the number of batteries inserted:

• 1A per slot when 1 or 2 batteries are charged
• 0.5A per slot when 3 or 4 batteries are charged

This system optimizes charging speed while preserving battery lifespan.

⚡ Smart charging technology
The MC4S uses a three-stage charging process (TC / CC / CV) allowing progressive and safe recharging:

• TC (Trickle Current): low current start
• CC (Constant Current): fast main charge
• CV (Constant Voltage): precise charge finishing

This system ensures a full and stable charge while preventing battery overcharge. The charger also automatically detects the type of battery inserted and adjusts the charge accordingly.

🔌 Wide compatibility with many batteries
The MC4S charger accepts a wide variety of rechargeable batteries used in vaping and electronics:

• Li-ion / IMR / INR / ICR
• Ni-MH / Ni-Cd
• Common compatible sizes:
• 18350, 18490, 18500

• as well as many smaller sizes (10440, 14500, 16340…)

Depending on battery diameter, some wider sizes charge using two slots.

🛡️ Enhanced safety
XTAR has equipped the MC4S with several electronic protections to ensure safe use:

• Overcharge protection
• Short circuit protection

The charger is also made from flame-retardant ABS plastic, enhancing safety during charging.

💡 Clear LED indicators
LEDs located above each slot make it easy to monitor charging status:
