The Short Version

Need to stay powered up on the go? The STANLEY PI500S Power Inverter is your portable solution!

What a 500W inverter can run

The PI500S is rated for 500 watts continuous, with two AC outlets and two 3.1A USB ports, so it can charge a phone, a camera and a portable speaker at the same time, or run a laptop and a small TV. At full load it draws roughly 42 to 48 amps from a 12V battery. That is more than a cigarette-lighter socket is usually fused for, so for anything above about 150W connect it to the battery directly. Heating appliances such as kettles, toasters and hair dryers draw more than 500W and are not suitable.

Who it suits, and who should skip it

It suits camping, road trips and light backup power for electronics and small appliances. Skip it if you need to run heaters, microwaves or power tools, or if you only ever charge phones, in which case a small plug-in unit is cheaper.
