The 70mai Hiker 400 is what everybody wants in a portable power station. It is tiny, lightweight, and can easily fit in a backpack. The plastic case is tough and integrates a small handle. A single fan provides the necessary airflow for the unit, producing barely any noise during regular operation. The NCM battery is not the best available in terms of lifetime, but with a capacity of 378Wh, it has enough energy to charge a laptop over five times.
The technology behind the 400W inverter yields an efficiency of 74% and limits the amount of energy wasted as heat. A built-in Bluetooth low-energy interface controls the unit over a short distance, allowing turning on the built-in flashlight remotely, among other things. The device features four USB ports, but only one is Type-C. Two AC sockets complete the output section.
