After using some of the cheaper battery pumps which eventually fail due to liquid getting into the battery compartment I spent a bit more on this pump.Nicely sealed and well made BUT awfully temperamental!There’s an inbuilt sensor to help the kit operate properly but it has to be angled just right not to cause the unit to switch off which means taking it out and fiddling around again.Great when it works - fast and efficient with good battery life but you do need patience!

If you’ve got the kind of 10L/20L containers I’ve got then the inlet nozzle won’t fit through the cap. Check before you buy.

Does exactly what it says on the tin. Really good and very professional. Couldn’t fault

This looked very similar to a much more expensive motorsport product that I've had my eye on for a while so I thought I'd give it a go. I wish I hadn't bothered. It leaks fuel from under the battery compartment in use. I can't even see how it gets in there. Once you've finished pumping it doesn't matter what you do fuel just pours out of it afterwards. I've tried tilting it, lifting it and waiting etc etc but there's always an appreciable amount of fuel left in the actual device. Finally it leaves a decent amount of fuel in the bottom of every container I've tried. It seems to need a certain level to pick up from. Sent it back for a refund.
