Which batteries does this charger work with?

It is built for WEN 20V lithium-ion packs. It is not designed for other brands' batteries or for older NiCad packs.

How fast does it charge a battery?

It is a standard single-bay charger, not a fast charger. Expect a full charge to take longer than a rapid charger would.

No. It has one bay, so you charge one pack at a time.

It connects through USB, so you need a USB power adapter or port. A higher-output adapter will not make it charge faster than its rated rate.

Yes, if you have a WEN 20V tool and need a spare or replacement charger. It does the same basic job without extra features.
