They work as designed.  Having a 2nd charger on-hand makes things quicker.  I hope the batteries have a long shelf life between uses because I use the camera almost weekly during the late winter and spring but monthly if at all in the summer and fall.

Good charger that works well at a great price. I liked it enough to get a 2nd one for backup.

This charger can supply 7.8A and can charge two smartphones and two tablets simultaneously.

It is not as compact as I expected but the foldable pins are helpful.

I bought a few extra, it's always smart to have more then you need. Just in case you forgot your charger on a trip.

I like this recharger because it charges batteries SEPARATELY, unlike most chargers which charge in pairs.

Works great!  Nice to have 2 USB ports to charge 2 phones simultaneously.

Works fine. Seems to charge a bit slower than others but being able to power two devices at once is worth it.

Very pleased to be able to charge 2 heavy duty items at the same time. Very fast charge without having to take turns for iPads/iPhones, etc.

so far so good, more expensive batteries are available but these suit my use just fine, having two chargers might benefit any one using them in making a living

Its a little on the heavy side but it charges good. I like that it has two ports to charge two things at once.

It works fine.  This is our second of these chargers which we gave to our daughter.

The plug can accept two U.S. plugs or two European plugs as long as at least one is ungrounded, so it is super convenient when you want to charge two appliances.

Although it is heavy, it does the job.  2 charging ports, one is faster than the other, but nice when 2 devices needed to be charged at once.  We never go on a long day trip without this in hand.

This charger does work as a fast charger and the two ports are a great feature for multiple devices.

Very good charger and comes with two batteries, also can charge other devices via the USB, and a very good price.
