Generic 4-Bay 18650 Battery Charger with LCD Display — Multi-Chemistry, Selectable 2000mA

The XKXKTkol 4-bay 18650 Battery Charger is a multi-format smart charger with an LCD that charges Li-ion, Ni-MH and Ni-Cd cells safely and at selectable currents up to 2000mA.

If you use removable rechargeable cells for flashlights, vape devices, cameras or other gadgets, the XKXKTkol 4-slot charger offers flexible charging modes and status monitoring for each bay. It accepts cells up to 72mm long (covering most 18650s and many protected/unprotected cells), provides automatic current selection plus manual options, and includes built-in protections to reduce risk of overcharge or short circuit. The charger ships with a car power lead, USB cable and a user manual so you can power up at home or on the road.

How does the LCD display make charging easier?

The backlit LCD shows per-slot details so you can check each battery’s voltage, selected charging current and elapsed time at a glance. Buttons let you toggle readouts and change settings without guessing, making it simple to manage multiple battery types at once.

• Individual readouts for all four bays (voltage, current, time)
• Button controls to view or switch charging parameters
• Clear icons for charging, full, and error states

Which battery types and sizes are compatible?

This charger supports Li-ion, Ni-MH and Ni-Cd chemistries and is designed for widely used cylindrical cells including 18650, RCR123A and similar lengths up to 72mm. It does not support standard 1.5V primary cells or some proprietary form factors.

• Accepted chemistries: Li-ion, Ni-MH, Ni-Cd
• Fits cells up to 72mm in length (most 18650 and protected variants)
• Not compatible with 1.5V single-use alkaline cells

How fast and adjustable is the charging?

The charger offers three current settings — 500mA, 1000mA and 2000mA — to match your priority of speed or battery longevity. Note that the 2000mA option applies only to the fourth slot; other bays are limited to lower rates for safer multi-bay charging.

• 500mA and 1000mA available across bays for balanced charging
• 2000mA high-rate charging limited to slot four for faster single-cell recharge
• Automatic current assignment with manual override via controls

What safety features protect my batteries?

Built-in safeguards help prevent overcharge, reverse polarity and short circuits so cells can recharge without unnecessary risk. The charger monitors voltage and charging time and will indicate errors on the LCD if a problematic cell is detected.

• Overcharge protection to stop charging at safe voltage
• Short-circuit and reverse-polarity detection with clear alerts
• Independent monitoring per bay to isolate problematic cells

Who is this for: The XKXKTkol 4-bay charger is aimed at hobbyists, photographers, flashlight enthusiasts and anyone who regularly uses removable rechargeable cells and needs a reliable, portable charging solution. It’s suitable when you want clear status feedback for multiple cells, the option to charge faster in a dedicated slot, and the convenience of both USB and car power options. Choose this charger if you value per-cell monitoring, multi-chemistry support and a compact four-slot design for home or travel charging.
