USB Battery (Ginger Series) for Olympus BLX-1 and Olympus OM System OM-1 / OM-1 Mark ii

Most of the time I buy the OEM batteries for expensive cameras. Big advantage of this unit is the built in USB-C port. It adds so much flexibility for power in the field. So far it seems to last quite a while and you can use a charger or just a USB-C plug to charge. Really nice always having a fresh batter to deploy. Very happy.

Cost effective for a backup. Does not last as long as OEM (maybe 80%) and battery shot count does not always reset.

OM System doesn’t include a battery charger for the OM3 so you have to charge in body via usb c. Since most people have a spare usb c cable around, it’s really nice to have a spare battery that can be charged out of the body, take up no more space than the battery itself and seems to work just fine. Highly recommend getting this as a spare.

So nice to be able to charge using USB-C. Works fine in my OM-1 Mark II. I cannot compare to the original relating to number of photos but for the convenience I don't care. I will purchase a second otherwise I still need a charger to recharge my original battery.

So far so good ... quite a few months of use in my OM-1 and it's holding charge well, last as long when not being used, shoots the same (maybe slightly more??) number of frames as OEM battery, and fits smoothly in/out of body (no swelling). The camera seems to adequately report it's charge percent as it is used. I have used it in the cold (<20F) ... it struggles with that about like the OEM. I can't speak to how it handles heat - have not been anywhere >100F shooting with it, have not left it in a sealed car in sun in heat. I'm not a fan of reviews right off the bat, especially for something like a battery which could go bad in a few months. (I've had quite a few non-oem batteries do that!) My positive review here is not how it looks or feels ... it's based on numerous cycles in use :) I see no difference in performance vs the OEM battery so far. The USB-C charging directly on the battery is great - that >>IS<< an advantage I see this having over an OEM battery!! If OM systems was going to cheap out on giving us a charger, at least these guys found a better way! Right now I don't need additional batteries, but if I do, given performance so far + direct USB-C charging, I'll buy this over an OEM OM-Systems battery. AND it's far cheaper. To me this is a win-win-win with this battery.

This performs at least as good as the originals. I haven’t done extensive comparison so cannot validate that it last longer. -1 star because the level reporting in camera is not accurate. I left the camera at 80% charge one day and the next morning the camera showed 90%. It took a few shots in use for the camera to report 80% again.

Shows proper percentage reading, charges off the cable or in the camera, this is a great product for my OM-1 camera!!! So far it works perfectly, will update after a few more charges. Don't need to carry a charger on my field trips at all now. I usually charge up my batteries in the camera, but this battery will allow me to carry more charged batteries into the field with me. Still testing to see if it provides as many pictures as the OM Systems battery.

I bought this as a back-up battery for my OM-1. I seldom exhaust a camera battery during a day's shooting, so didn't want to spend $100 for a second Olympus battery. I also appreciate the ability to charge the Wasabi battery by USB-C since I don't have a separate charger. Both batteries seem to have comparable performance and each lasts though a day of shooting. I've had Wasabi batteries for past cameras and never had any issues with them.
