Usage Features

The Powxs SW-2 charger is designed for straightforward use. To begin charging, simply plug in the micro USB cable and power on the device. The LCD screen will light up, indicating readiness. Insert rechargeable batteries into the appropriate slots, paying close attention to the positive and negative poles. The LCD screen will then display the battery capacity using a visual indicator (flashing for charging, solid for charged, and different segments for capacity levels: <25%, ≥25%, ≥50%, ≥75%, 100%). If a battery is inserted incorrectly (in reverse), its corresponding icon on the LCD will flash, signaling an error. It is crucial to insert batteries correctly to prevent short circuits or fire hazards.

The charger is compatible with a range of rechargeable batteries, including 18650, 18490, 18350, 17670, 17500, 16340 (RCR123), 14500 Li-ion batteries, and AA/AAA Ni-MH/Ni-CD batteries. It is important not to charge incompatible batteries, as this could lead to leakage or explosion.

Maintenance Features

To ensure the longevity and safe operation of the Powxs SW-2 charger, several maintenance and safety guidelines should be followed:

Cable and Adapter: Always use the micro USB cable provided by Powxs and a 5V/2A power adapter.
Battery Compatibility: Only charge compatible rechargeable batteries. Charging incompatible batteries can cause leakage or explosion.
New Batteries: New batteries typically achieve their best performance after 3 to 5 charge-discharge cycles.
Heat During Charging: It is normal for batteries to become warm during charging. They will cool down to a normal temperature after charging is complete.
Post-Charging: Turn off the charger and remove the batteries once charging is completed.
Disassembly: Do not disassemble or reassemble the charger, as this could cause a short circuit.
Damaged Batteries: Do not charge batteries with damaged covers, as this poses a risk of short circuit and fire.
Obstruction: Do not place anything on the charger while batteries are charging, as this can lead to heat accumulation and a fire hazard.
Environment: Use the charger indoors only. Keep it away from direct sunlight, moisture, and high-temperature environments.
Child Safety: Place the charger out of reach of children. Children should only use this charger under adult supervision.
