Does this charger work with the PL-PRO Valkyrie?

CS reply:

Dear customer, Universal Battery USB Charger doesn't work with the PL-PRO Valkyrie. It is a universal magnetic USB charger for most single cylinder rechargeable lithium or NiMH batteries of variable sizes.Thank you for your support to Olight.

This does exactly what it claims. I really like it. It charges li-ion and NiMH batteries. I have had issues with some NiMH batteries not getting a full charge from it, so I tend to only use it for 18650s. There is one con and that really can't be avoided unfortunately. That is the weight. It is a bit heavy because of the magnets that attach it to the terminals of the battery. Can't really do the universal thing without them though. I have moved away from using it and replaced lights with ones that have a charging circuit built in, or only travel with a charger for a single type of battery and choose devices that all use just that type because a plastic holder for a battery with a charge circuit and plastic housing weighs less than this universal charger. Just something to consider if you are trying to shave grams off your bag for travel or hiking.
