Generally speaking, if it is a short-term camping trip and only charging a few small devices such as mobile phones and cameras, a 500 - 1000Wh capacity outdoor power supply can meet the requirements; for long-term outdoor operations, group travel, or scenarios that require driving electric ovens, drones, etc., with high-power equipment, it is recommended to choose a large-capacity product of 1000Wh or above.

Tonga Renewable Energy Project (TREP) has three components: (i) a large BESS capacity on Tongatapu to ensure that the intermittent electricity generated from solar photovoltaic and wind power to be funded by private independent power producers can be stored and used overnight without negatively affecting Tonga Power Limited's grids; (ii) electricity generation from the most feasible renewable resources in Tonga in Eua and Vava'u islands, and in five outer islands (O'ua, Tungua, Kotu, Mo'unga'one, and Niuafo'ou); and (iii) grid technologies and management upgrade to adapt to new electricity sources in five outer islands.

This means that the power supply can “start-up” or be “turned-on” with an ambient temperature as low as -40°C (below the -20°C spec) and deliver 100% of its rated power, however, the power supply’s output regulation, hold-up time, ripple & noise, and other specifications cannot be fully guaranteed until the power supply warms up to at least -20°C.
