How to use

Charge the powerbank from a USB power source before first use for faster availability. In daylight, place the device with the solar panel facing direct sunlight to allow the 400mA solar cell to slowly recharge the internal battery. Connect devices using the appropriate USB cable to transfer power from the powerbank to your device. Observe device charging indicators to avoid overcharging external gadgets.

Usage recommendations

For best results, pre-charge the SL-100VC from mains power before heading outdoors. Use solar charging as a supplementary or emergency option due to the modest 400mA input; full recharge by solar alone may take many hours depending on sunlight. Store the battery in a cool, dry place when not in use and avoid prolonged exposure to extreme heat.
