Works perfect. in the long run this will save you batteries. Plus with four in the pack you always have a spare when you run out of juice. Review: Good for NiMH batteries, but look for Lithium Ion batt's for best performance today - Nice small form factor charger set with four AAAA batteries included. This is a NiMH model. Better than NiCd but not as good as the newer Lithium Ion technology. NiMH imseems to be the most common battery tech currently due to its product maturity and value over the oldest NiCd tech, which only stays rechargeable for a year or two if you're lucky. The total voltage is slightly less per battery than "normal" non-rechargeable Alkaline batteries so they will not last long in power hungry devices. If your standard Alkaline batteries lasted a year in the device, expect NiMH to last maybe 30-90 days before recharge. ## Features - ★ Battery Type: Rechargeable Ni-Mh AAAA Battery; Capacity: 450mAh; Voltage: 1.2V; Premium Grade A cell for longer battery life with no memory effect； - ★ Compatible With: Surface pro 3/4 pen, Digital pen MS(Microsoft）surface pen, Dell digital stylus, Bamboo ink pen, Active stylus pens, Asus stylus, Sonic tooth scaler, Video game controllers, Bluetooth headsets, Glucose and blood monitors. - ★ Ni-MH eco-friendly cell, doesn’t contain Hg/Cd/Pb, makes no pollution to the environment, and using DBCK steel shell which can protect the battery against explosion due to overpressure. - ★ 4-slots independent charger design is convenient to charge batteries simultaneously and independently, saving your time, saving your batteries' life.
