Great for charging batteries

Great for my stylus. Has saved me a lot of money from buying single use batteries. The charge is a little less than a single use battery, but not much.

Excellent little charger. Very solid snug battery grip via a slider. Very happy

Does the job, however the charge only lasts a few hours on the batteries provided in a tablet pen, compared to disposable which lasted a whole month.

These are the best value AAAA batteries I've found anywhere. Rechargeable batteries do cost a little bit more than single use ones but wmhave the benefit of buy once and reuse many times. I like that this comes with a USB charger already so I didn't have to try to source one separately. The USB charger plugs in to my Surface Pro so I can charge the battery easily for the pen that goes with the Surface.

What i like:* Great idea and only stumbled across this when looking for yet more AAAA batteries for my HP active pen* Charges over USB - how brilliant is that* You get 2, so can have one recharged and ready to go* Small, compact and easy to just throw in your bag.What i dislike:* Seems like they don't last as long throw away types but could be how much i used it now compared to previously.I think this is a decent buy, even if it doesn't last as long as the throw away ones, it doesn't matter, you save on money and help the environment by getting these and its far cheaper than spending more money on a stylus with built in rechargeable battery. Plus, when you run out its simply a matter of popping the other one in, or worse case charging this up - but still better than having to wait for tomorrow to get some, or worse trying to hunt for them in shops.
