High pressure washers with built-in battery

Built-in

— a battery that is built into the chassis and is not designed to be removed and replaced by the user.

This design somewhat reduces the overall dimensions compared to models using replaceable batteries; and the battery itself is by definition supplied in the kit. However, this is where the advantages of this option, in fact, end. And its key drawback is the actual inability to remove and replace the battery if desired; Several practical implications follow from this. First, when the energy supply is depleted, the only option is to charge the battery — and this requires a source of energy and takes a lot of time. If the characteristics of the battery do not suit you or it is out of order — again, you can’t just buy and install another power source: in the best case, you will have to contact a service centre for repair, and in the worst case, you will need a complete replacement of the unit.

As a result, built-in batteries are extremely rare nowadays — in separate low-power units designed for occasional use for simple tasks and, on the whole, designed for ease of carrying from place to place.
