Work as expected

Exactly as advertised and yes, Great value,you get four

Great price!

These worked great for charging my pen. And if I loose knee I have 3 more! Great price for 4 chargers.

Must have for any pen user

This charger is a must have for vaping. It is so hard to find them and if you lose one then you have to search for them. This came in a multipack so I can keep one in my car, home, and office and still have an extra, and never be without. I am so happy that I found these at such a good deal. I'll never have a dead battery again.

Works great

Got these for my hubby after trying a few others that stopped working after a day or two. Going strong with these after a week! Charges his cartridge pretty quickly.

Work as expected

Ordered for my office at work. I.T used them and they worked as expected

There’s FOUR!

Wow! I didn’t realize there were four in this pack! At the local shop, one of these is $6. Can’t say much about these since they’re pretty simple to use. I just charged my battery and it works well. I like the different color indicator light to let you know that it’s still charging. Glad there are four of them because they will probably burn out eventually. I’m sure this pack will last me a while though. What a great value!

Great quality
