Hama 20000 mAh - powerbank, Black

The Hama HA-00201755 20,000 mAh Power Bank, Black, is a portable charger with a 20,000 mAh capacity for charging devices away from a mains outlet. Its stored energy can charge devices repeatedly, although the number of charges depends on the device. It supports fast charging, but no charging protocol or maximum wattage is specified. No USB Power Delivery rating or total output power is provided, so its charging speed cannot be compared by wattage. Listed compatible devices include phones, tablets, headphones and headsets, portable speakers, smartwatches and digital camcorders.

The black, rectangular unit weighs 425 g and measures 143.3 × 68 × 29.5 mm. Two USB-C output ports and one USB-A output port allow up to three devices to be connected at once. An LED display shows the battery status. The power bank recharges via USB-C, and a 0.3 m USB-A-to-USB-C cable is included. Its USB-C input also allows it to be recharged without a separate type of cable.
