Such a good deal

Instead of buying one charger for ten bucks I get a whole pack for cheap. such a rad deal

Just works

They work and there’s five of them. May not sound impressive, but it is when you consider that half of what’s being sold out there doesn’t.

They fit most pen batteries.

Like anything the charges and the batteries don't last forever and this is way cheaper than in the smoke shops. They quickly charge the batteries.

Work well

These fit well into what I needed to charge. It charged rathet quickly. It may just be my imagination but my items seem to hold charge longer than before. At this price, can't go wrong.

Great product!

Great product, inexpensive too!

It's 510 thread

Its what you need for replacement

good

When I bought my pen I was provided the cheap knock off charger and they stopped working months later. When looking for a replacement I didn't want to buy the knock off again and found the maker of the pen has its own (not provided with new pen) and bought this for a few dollars more. Its great. Charges like it should and has been working without issue.

Works great

These were a much cheaper alternative to the name brand that came with my device. they seem to be of good quality and work great. The 4 pack is perfect for me to have one in several places.
