Heres a decent discount taking this pad down to a very good price of £11.19.
It has been down to £9.99 for a limited time twice over the last couple of months. So if you’re not desperate you could risk waiting to see if it goes that low again.
Note, this doesn’t come with a charging block.
So ensure you have one with enough output to feed this!
