Ordered what I thought was one at just under £10 all in. I actually got ten, hence my title! Arrived on time., well packaged. For the price I really can’t fault the quality. Two, small, gripes. Firstly, there is a hole which appears to be for a small screw to stop the possibility of the lid coming off. No screw though, and nothing I’ve tried fits. Secondly, there is no indication on the unit as to the polarity of the plug. I had to test it and confirmed it to be Centre +‘VE, which is the opposite of every piece of kit I’ve ever owned. Fiddly but straightforward to re-wire for -‘VE centre but there is kit out there that would fry if inadvertently plugged in to a ‘wrong way’ supply. Review: Nice 9v battery box - Only really needed one, so now have many spares! Great little 9v battery box with inbuilt on off switch. Needed a different polarity but was easy to de-solder and resolder the connections the other way around. ## Features - ON OFF Switch, 20cm long Cable with 2.1x5.5mm DC Power Plug. - Easy to remove sliding cover with a hole for a screw to lock the cover down.
