Why choose a portable solar battery?

A portable solar battery combines an energy storage system (lithium or LiFePO4) with the ability to recharge via solar panels. It allows you to remain autonomous without a grid connection — ideal for camping, van life, construction sites, or preparing for power outages.

Our selection criteria

• Real capacity: measured at the output, not at the input (conversion losses count)
• AC/DC output power: suitability for your devices (fridge, computer, tools)
• Cell technology: Lithium NMC vs LiFePO4 (lifetime, safety, weight)
• Charging speed: solar, mains, car — how long for a full charge?
• Weight and portability: Wh/kg ratio for nomadic use
