Effective but not ideal for travelling as there no case or bag,
This review is from: Ring Automotive 500W Powersource Inverter with USB (Automotive)
Customer review from the Amazon Vine Programme (What's this?)
It's too powerful to be ran off your car's cigarette lighter socket, which means you're not limited by your car's lighter socket fuse, so remember you'll need to open the bonnet of the car or have a loose battery. The wires are long enough that you don't need to sit on top of the battery to use your device and the USB socket means you can charge your phone, tablet etc with just the right USB cable.
The packaging is not great, being one of those sealed plastic packs so you're going to need to cut it open, which means you don't have a box to keep the inverter in and as it has wires (to connect to the battery) dangling from it it does need something to protect it in the car boot or caravan.
