Product Information

Full details

The Vax ONEPWR 4.0Ah Battery and Charger Kit is designed for homeowners who own multiple Vax ONEPWR cleaning tools and need a reliable, swappable power source to keep their devices running longer. Its primary benefit is the universal compatibility across the entire Vax ONEPWR range, providing a consistent power boost for stick vacuums and other cleaning appliances. One caveat is that the 3-hour recharge time may require users to rotate multiple batteries if they have extensive, whole-home cleaning tasks to perform in a single session.

Setup, Compatibility & Care

Setting up your Vax ONEPWR kit is straightforward: simply slide the battery into the charger port until it clicks. The charger will indicate the charging status via the LED lights. To ensure compatibility, verify that your appliance is part of the ONEPWR range; no adapters are required as the design is universal across this specific ecosystem. For long-term care, store the battery in a cool, dry place and avoid leaving it on the charger indefinitely after a full charge is reached. Periodically clean the metal contacts on both the battery and the vacuum with a dry, lint-free cloth to maintain a solid electrical connection.
