FUGASUN LCD Intelligent Battery Charger for 21750/21700/18650 | 75mm Slot, USB, PCB Protection

Overview

Meet the FUGASUN 21750/21700/18650 Battery Charger with an LCD interface that makes charging multiple cells simple, organized, and safer. The design balances a compact footprint with a generous 75 mm long slot to accommodate longer cells, including protected Li-ion and Ni-MH chemistries.

Smart, adaptive charging

The charger uses per channel LED indicators and an LCD readout to show current charging status. You can select charging currents 0.5A, 1A, or 2A, with 0.5A for Ni-MH types to tailor charge time and reduce heat buildup. This helps manage the condition of each cell while you monitor progress at a glance.

• Per channel information on the LCD keeps you informed about each bay without removing batteries.
• Simple button controls let you switch between current settings, helping you optimize for Ni-MH or Li-ion cells.

Broad compatibility

The smart charger is compatible with a wide range of rechargeable cells, including Ni-MH, Ni-Cd, and many Li-ion formats. It supports common sizes such as 10440, 14500, 14650, 16340 (RCR123), 16650, 17650, 17670, 18650, 20700, 21700, 22700, 26650, 26700, and newer high capacity cells up to 3600 mAh or higher. This makes it a versatile option for flashlights, remotes, and everyday devices.

• Long-slot design accepts batteries up to 75 mm, including 21750, 21700, 20700, 26700, and 26650 with PCB protection built in.
• USB powered for charging from a computer, power bank, or wall adapter.

Safety and care

A built-in PCB protection board helps manage charging safety, and it is important to follow charging best practices, avoid keeping devices on charge indefinitely, and monitor for changes in voltage or warmth during the process.

Real life use scenarios

Charge spare cells for your LED torches, action cameras, or handheld devices. Keep different chemistries organized in separate bays, and use the LCD readout to verify status before swapping batteries for your next outing.
