The WakaWaka Power Pro is a compact power bank designed to keep your devices topped up when you’re away from the grid. Whether you’re hiking, camping or simply spending a day outdoors, this unit holds enough juice to be a reliable backup for your phone or other USB-powered gadgets.

With its 10,000 mAh battery, the Power Pro can typically recharge a smartphone two to three times before it needs refilling. It accepts up to 20 W input, so you can restore its capacity in about 3½ hours when paired with a compatible charger. At roughly 10.5 x 6.9 x 1.4 cm and 195 g, it slips easily into a pocket or pack without weighing you down.

Battery capacity, shown here as 10,000 mAh (milliamp-hours), indicates how much electric charge the pack can store. Higher mAh means more cumulative power for your devices. The 20 W charging rate refers to how quickly the power bank itself refills: a higher wattage input cuts the waiting time compared to standard USB chargers.
