Description

MH-5D84HP USB-C 4-Slot 18650/21700 Charger | 4.2V 4000mA, Independent Charging

A four-bay USB-C charger designed for 3.7V lithium batteries. The packaging marks Input: DC 5.0V ±0.1V / 2A–4A and Output: DC 4.2V ±0.1V / 4000mA. Each bay works independently, with a two-color LED—red while charging, green when full—and a printed bar scale showing 25% 3.2V / 50% 3.6V / 75% 3.9V / 100% 4.2V. Supported sizes listed on the box: 18650 / 21700 / 26650 / 18500 / 14500 / 16340. Photos show a USB-A → USB-C cable included. The box also carries CE and RoHS icons and the callouts “High speed charging / Independent charging / Red full automatic stop.”

Care & safety (from the box text)

• Do not charge non-rechargeable batteries.

• Avoid short-circuiting, disassembly, and high-temperature environments.

• Do not mix rechargeable cells with dry or nickel-cadmium batteries, and do not charge different capacities/models together.

• Do not charge damaged or deformed batteries; keep away from heat, wetness, and humidity.
