AAAA Batteries Rechargeable for Surface Pen Active Stylus - Size AAAA Battery Ni-MH 1.2V 400mAh - 2 Count (Charger Included)

Awesome purchase, so far! They both charged and the first one is in my laptop pen... been working a couple weeks, so I'm totally happy with it! Can't find AAAA batteries at just any store, and the last 4 pack of Amazon batteries only had one my pen liked.. so I've already gotten my money's worth!

The bundled charger can charge any Ni-MH battery (AA, AAA, AAAA) with a USB-C power source. It can be placed on the desk while charging and is much easier to use compared to those wall chargers.

It does the job. I bought it because theres never aaaa in stores I used them for a touch screen hp pen and it works good I haven't had them long enough to say they are good for longevity. One thing that's a bit annoying is it only charges one battery at a time.

This is a great value for the money and works as well as other, more expensive brands. It is perfect for items that only require 1 battery, as you can only charge one battery at a time.

Small and easy to travel with to make sure tablet pens are recharged when needed. Not much to say, other than works as expected and for a good price.

after a few weeks of charging, have not been able to get more than half full capacity. these batteries will not be usable with a Microsoft Surface pen. the charger is bare bones but seems to function correctly. not recommending.

I like that it has a USB connector that can be hooked up straight up to my laptop. I use it for my laptop stylus.

I purchased this item so that I can recharge the batteries for my stylus pen. It works as expected.
