Powiser has unveiled a couple of new VOLIX 3 P-series models, signalling the start of an expanded range of products in 2026. TechPowerUp spent some time at the power system specialist's CES booth, where we took a closer look at two outdoor-centric models. Starting with the physically larger VOLIX 3 P4000 demonstration unit, a TPU staffer took note of a rugged handle bar and set of wheels. Adventurous outdoors-types can lug this 4096 Wh LFP (LiFePO4) battery-based power station across the ground, rather than carry it. As befits this SKU's moniker, claimed AC output is 4000 W, going up to a surged 8000 W level. AC power input goes up to 1800 W, while solar input maxes out at 1600 W. A total of ten output ports can power a great variety of electronic devices. When inspecting the VOLIX 3 P4000 back section, TPU spotted two external battery expansion bays.
