The exact watt-hour specification is missing from the product data. To calculate it, you need the nominal voltage of the battery (usually 3.7 V for power banks): Formula Wh = (80000 mAh × V) / 1000. At 3.7 V this results in about 296 Wh, but without official voltage I cannot confirm this for sure. Check the operating instructions or ask in our Community.
The exact dimensions of the device are not available. The weight is around 1.7 kilograms, which makes the power bank relatively heavy and more suitable for stationary use or emergencies.
Charging via solar power takes several days with this power bank, even in direct sunlight. The solar function is intended more as an emergency solution. The cable should always be used for regular charging.
The wattage of the power bank is not specified directly. The performance of power banks is normally determined by the connections and the supported charging types. The power bank has several USB ports, including USB-C, which often enables higher charging capacities. If you need the exact wattage, I recommend contacting the official product description or the manufacturer.
