Portable Battery VOLTCRAFT SL-240 24000 mAh
The VOLTCRAFT SL-240 portable battery (24000 mAh) is a high-capacity power bank for charging smartphones, tablets and other USB-powered devices. It combines a large internal battery with integrated solar cells so the unit can recharge slowly from sunlight when placed in a bright location, and charges faster via USB when a cable is connected. The slim black housing includes a built-in torch with an SOS mode for emergency signalling.
The power bank offers a 24000 mAh capacity for multiple device charges, two output ports (USB-A and USB-C) for simultaneous charging, and dual charging options: solar recharging for slow, maintenance charging and USB input for faster recharge. An LED indicator shows charging status (green while charging, blue when fully charged). The built-in torch provides continuous light and an SOS function for emergencies.
To charge the power bank faster, connect a USB charging cable to the USB input and a compatible power supply. To top up the battery passively, place the unit in a bright location or on a windowsill so the integrated solar cells receive direct light; solar recharging is slow and intended for maintenance rather than rapid charging. Connect your device to either the USB-A or USB-C output to charge it. The LED indicator lights green while charging and turns blue when fully charged. Use the built-in torch and SOS mode by pressing the dedicated light button.
The solar function is useful for maintaining charge but is not a replacement for USB charging; use direct USB charging for faster recharges. Store the power bank in a dry place and avoid prolonged exposure to extreme temperatures. Regularly recharge the unit if stored long-term to preserve battery health.
