Jackery’s Explorer 300D sits in the brand’s smaller portable power station line-up, aimed at light camping, van days and backup power at home. It competes with compact units from EcoFlow and Anker, focusing on a sensible balance of battery capacity and usable output rather than sheer size. With a 288Wh battery and 300W output, it suits charging phones, tablets, cameras and keeping small mains gadgets running for short spells, but it is not intended for high-draw appliances like kettles or hairdryers.

Who is this power station for?

If you want a quiet, fuel-free way to keep essentials topped up away from a plug socket, this fits. The 300W ceiling matters because it dictates what you can run from the AC outlet, while 288Wh is your “fuel tank”, so expect best results with low to moderate loads.

  • 288Wh capacity: better for charging and short runtimes than powering heavy appliances.
  • 300W output: suitable for small electronics and modest mains devices within that limit.
