Charger style voltage meter?

[tearose50]

I would like to have something that looks like a single charger, big enough to hold an 18650, but has a digital voltage read out showing the voltage.

The idea is to have a more convenient way to check the charge level of my batteries before and after charging.

Does such an animal exist? Has anyone made one?

And/or -- are there mid priced chargers for our types of batteries that have this added function?

Thanks,

Hubby bought something similar from RadioShack. It will expand but I don't know up to what size battery you can put in it.
