Wasabi Power Battery (2-Pack) and Dual USB Charger for Olympus BLN-1, BCN-1 and Olympus OM-D E-M1, E-M5, Pen E-P5

The Wasabi batteries work very well in my Olympus OMD. All of the display functions are present, and they last as long between recharging as the Olympus battery (this may be a little subjective as I maintain no log as to the number of exposures made with each battery.). When out and about for the day there is always a spare, freshly-charged, battery in my pocket or gear bag Practically, I see no difference, other than price, between these and the Olympus-branded battery. This new charger is really handy. It is much smaller and lighter than either the previous Wasabi or Olympus chargers and, therefore, much easier to stow in your gear bag or carry-on. And, being USB powered and since the entire civilized world seems to be becoming inundated with USB outlets, it may be used almost everywhere. I have been using Wasabi batteries in two OMDs and an XZ-2 for several years and have never been disappointed. They have become my batteries of choice.

This is probably the 5-6th Wasabi charger I have purchased for various cameras over at least the past 8 years or so. They consistently work, are fairly easy to pack due to compact design and can be used with a USB hub, reducing the number of mains receptacles you need to find in a hotel room while traveling. Being able to charge 2 batteries at once is very useful when traveling, which is why I purchased this double charger. As far as batteries go, I have had consistent good luck with Wasabi Batteries working in a variety of Canon, Panasonic and Olympus cameras. They generally perform as well or better than the expensive brand name batteries despite their very low cost (in comparison).

works well

This is the second time that I order these batteries. The first set became bulky, so they don't fit in the camera anymore. After filing down the excess plastic the batteries fit once again but the battery life is considerably shorter. So they reach their end of life. But for this price you can buy several sets of these batteries before you reach the price of the original Olympus batteries. So all in all I am satisfied with these batteries.

Besides being able to charge 2 batteries at a time, compared to a single battery with the Olympus charger, it also seems to charge them much faster. I now use this all the time instead of the original charger.

It was what my husband needed

Fitment was perfect and currently being used. Hard to determine life expectancy but seems to have lots of life

I have originally owned these batteries in 2019 and after several years of use, the battery life finally reached its end. For an off-brand battery, I'd say that lasted for quite a long time. Thinking I'll have the same experience again, I decided to purchase two sets of battery packs this time. Boy have the times changed. Upon arriving, the batteries fit in the camera and works just fine. So I packed it for our trip and placed it inside my camera bag next to my older Wasabi batteries as well as my original Olympus battery (which is still rocking on by the way). After arriving at our destination, I opened my camera bag and found all four batteries have ballooned and expanded to a point that it no longer fits inside the camera. It was highly concerning especially after hearing about exploding batteries in airplanes. It could've happened to us. The camera bag went through x-ray and brought on the airplane, which is as routine as it gets. The other batteries have no issues and are placed directly next to these batteries in the same bag. Only these four batteries reacted this way. I have contacted Wasabi for an explanation and resolution. Unfortunately I was not able to ship this back to them because that would require either flying back with it or figuring out how to ship it back to them from our international location. I want to avoid a potential fire hazard. I cannot recommend buying these batteries at all seeing that this is how it reacted to traveling.

It works as well as the original battery value for money

These batteries don't seem to last quite as long as OEM batteries, but they're far cheaper and thus good value for the money. The included USB charger is very handy for charging batteries on the go (in the car, etc). The charger will charge both Wasabi and OEM batteries, and the OEM charger will charge the Wasabi batteries, which is nice. Given the so-so battery life on most mirrorless cameras (compared to old DSLRs), whenever I get a mirrorless camera the first thing I do is buy a few extra batteries...at this price, it's worth getting this package just to have some peace of mind in your bag!

Arrived sooner than delivery date and so far works great.
