I have a Pentax K20D I purchased in 2009. I also purchased Pentax batteries. In the past few years the lifespan of those original batteries has been diminished greatly. I searched for Pentax replacements, but, ouch, that was a lot of money. I might have accepted the cost, but my DSLR is 11 years. I'm considering replacing it, so I certainly didn't want to spend full price on Pentax replacement batteries.These worked great. They lasted several days through a lot of shooting under a variety of weather conditions from near freezing to 100° F. The batteries performed as I remember the original Pentax batteries performing when they were new.I also love the charger. I like the display that shows battery level.I'm very happy with this product.

Two batteries, a nice multi powered charger in the sense you can plug the power cord into a USB outlet in your car or home if you have the adapters in place; most new cars have them now and if you do not the adapters for the power socket are commonly available. Laptops, PCs and so forth all have them too. You can charge your camera battery with this most anywhere. The good thing is with the extra batteries you can keep two charged in your camera bag and swap them out as needed. The charger has a LED scale to show you the battery state of charge and charges them up quickly. It all seems well made and certainly functions very well.

I just wanted to have an extra couple battery packs if I ever need them. The charger it comes with is tinyyyy but imo that makes it better, and the chargers plug is USB, it's easier to travel with! Works fine with my old Konica Minolta.

Great value for the cost.

i like the compactness of this charger pack

Bought this to recharge batteries for my Minolta A2 battery pack. Very happy with this device.

Only way to go for heavy gaming.

After the first charging of my batteries, I unplugged the chargers "USB C" plug and it pulled out the connection inside the charger unit. Batteries are fine. Charger in the trash. Sad. 😕
