These Little things are great. Compared to the OEM charger that comes with the camera. And it requires 120 volts. And it takes like two or three hours to charge. This item takes 5 volts off a USB and I don't know what it trickery it uses but the battery charge up very fast. And you can charge two of them instead of one. It's great I have two of them. They take up pretty much no space whatsoever, they are extremely light, and you can connect them to pretty much any available USB source. I have four batteries now. And they're super easy to use. Are they a good value for the purchase? Well I can't say that I can compare them to competing products, but compared to that thing that shipped OEM. Yes these are a great bargain.

Necessary addition for the OM5: it comes with no charger, only an ancient mini USB port on the camera for charging the included battery. The two batteries so far seem supply at least 80% of the OEM battery. The OEM battery, being physically small and the camera actually a computer dedicated to taking pictures, doesn't last all that long either so this kind of thing is a must-have.

The batteries work great with the new OM System OM-5. The battery longevity seems to be on par with the factory-included battery. The charging time is not the fastest but it's certainly faster than charging the battery through the camera. There are a few drawbacks with this set that leads me to deduct one star from the overall rating.The first drawback, the connection point feels a bit iffy right out of the box. When I tried to charge the two batteries with the charging dock, one of them would light up while I have to reseat the other one in order for the charging light to come on. It might be a one-time thing so I will have to keep an eye out and see if this would become a constant issue.Second, the way the charging dock requires the batteries to be placed upright means that the set would take up more room in my camera bag. The previous charging dock for my Sony camera places the batteries horizontally, making it space-saving when I need to pack the set in my bag.I'll come back and update this review if I come across something else. For now, these batteries and charging dock set is working well for what I need.

worked great

I travel with my camera. I keep several batteries charged in advance so it’s fast and easy to replace a battery. We won’t miss a shot.

It comes with a USB type A to type C cable, not micro usb. They might have upgraded the interface. This is a plus because everything should turn to type c.Also the battery works with my OM-5

I’ve ordered from Wasabi power in the past and have always been really happy with the quality and performance of their products.Naturally I decided to buy some of these for my new OMD Em5iii. Just through sheer bad luck, one of the batteries happened to be a dud and wouldn’t charge. First time I’ve ever had to call in to their customer support and happy to report they really take care of their customers. Definitely one of the best customer services I’ve ever gone through.Forgot to ask the name of the guy I talked to but he was crazy helpful. Asked a few questions to verify the purchase, understood my problem with the dud battery, and immediately offered a remedy to the situation. In this case offering not one but two batteries to make up for this! (Ofc don’t be going in expecting this and taking advantage of them)Will definitely be using these batteries a ton of my upcoming outings so the extra battery will come in super handy.Can’t recommend these guys enough. Thanks :)I will mention the battery charger in this kit is a bit tight on the battery though. Guess it means it’s pretty secure once in there but definitely takes more effort to put in than I thought. Other than that the battery fits perfectly in the camera.

As best I can tell, the battery charger works well. The batteries on the other hand are complete junk. One died within months. The other sometimes seems to be OK, but often than not is bad in the camera and doesn't interact at all with the charger (the LED won't turn "ON" when the battery is inserted).The batteries from the camera manufacturer (Olympus) on the other hand still work great 4 years later.
