Review: Does what it said on the tin! - A handy gadget to keep in car and it can charge other electronics items as well. Mine came with a UK plug and it worked the first time when husband had to jump start his car. I was a little worry after reading the other review and the pictures, so I paid extra attention when it was charging. The power bank doesn't really get hot when it was on charge so it eases my worry.
Review: All there - EURO PLUG - This looks good quality. Beware though - the power supply has a euro plug - so you will need to convert for use in UK sockets - took off one star for this. You can use the adaptor that you use for your shaver. Haven't used it yet - fingers crossed may never have to use it - but it's there in an emergency.

### ⭐⭐⭐⭐ All there - EURO PLUG

### ⭐⭐⭐ Potentially brilliant, if you get one that will fully charge.
*by G***N on 27 June 2020*

I love the feeling of this bit of kit, feels great in the hand, one major problem was, it would not charge to 100%, no good to me, it’s clearly a one off issue, because everything else is brilliant one minor problem, it has an EU plug on the charger cable, and selling it to the UK market is a pain in the arse if you have not got an adapter.
