  • Great charger

    Posted by Phil Wright on 4th Jul 2023

    I use rechargeable batteries often - whether it's in my vaping device or the remote for the telly so I needed a charger that could charge my bigger and smaller batteries. Safe to say that this charger has done a good job so far. Clever device, switching to a smaller charge for my smaller batteries. Would recommend.
