Can anyone recommend a USB charger that plugs into the wall that has 4-5 separate USB plugs? I’ve got a few lights that need charging once a week or so for commuting, they all plug directly into the USB port and a box I can plug them all in to would be handy.

Budget of £20 or so.

I have a couple of Anker ones from Amazon that I’m happy with

Anker.

Portapow are very good and understand the quirks of different device manufacturers. I’ve had one of their older chargers for donkeys years and it’s never missed a beat.
