  • What's the recharging ways of B500K?

    B500K’s charging input matches that of its host power station, enabling simultaneous charging via AC, solar, car, or generator. It can also be charged independently using compatible accessories such as SolarX 4K or alternator Charger.

  • How long can it run my device?

    Runtime (estimated)= 5,120 Wh × 0.88 ÷ (Device power + 3W)

    * The actual working time may vary under different conditions. The 3W represents the self-consumption of the B500K, and 0.88 is the conversion rate.

  • B500K & Apex 300 charge together, reaching 80% in 1.6 hours. Does this mean both reach 80% simultaneously?

    "80% charging in 1.6 hours" refers to the B500K's maximum charging capacity.

    If the solar generator's input power is insufficient, it will not be possible to charge both devices to 80% in 1.6 hours.

  • How many B500K batteries can I connect, and can I mix them with other BLUETTI expansion batteries?

    Up to 6 units depending on the model (6 for Apex 300 or AC500, 4 for AC300, 2 for AC200L orAC200MAX). The B500K can also be mixed with B300, B300S, and B300K batteries, provided the power station supports those battery types.
