HALJIA 10Pcs 9V Battery Holder Project Box with 2.1mm x 5.5mm DC Plug and On/Off Switch Case Cover Compatible with CCTV, DIY, Arduinos, motors, solenoids, LED strips

Well, searched everywhere, finally found this PP3 box. 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.

Real value for money AND very handy for keeping those 9v batteries safe. Has an on/off switch which is an added bonus. Would recommend.

Very well made, not flimsy. Works great. Excellent value for a a pack of 10.

Great bit of kit. Value for money

perfect for all those projects needing a 9v power supply
