Booster popped with smoke coming out
Hi, I returned from hholiday and switched on all of my electrics. When I switched one of the booster packs back on, it literally popped and started to release smoke, thankfully no fire and my plug ...
Do please report this very serious incident to Trading Standards and retain (but not use) the booster as evidence https://www.tradingstandards.uk/consumer-help/
