Cooper Instruments Load Cells

I shouldn't be this enthused about a battery caddy ... right?! This one just works well. The cells load/unload easily, yet stay securely in place. Face them up for charged/ready to use. Face them down for needing charging. No chance of short circuiting like in a sandwich bag. The only down side I see is that I wouldn't want to carry this in a pants pocket. A sport coat pocket, on the other hand, would work fine.

Excellent product, the best way to test batteries or cells is under load. This is what his device does very well. Very often when I go to find a battery for a device and it does not function, I cannot tell if the device is bad or the battery. This device corrects that problem. Very Happy with this device. Powered off of 4 AA cells, recommend you use Lithium Cells,

These cells work quite well in my Canon.

Great for Vocal and Instruments!

Does a nice job at protecting 123 cells.

The Tenba Cooper Slim Backpack (Gray) is the second Tenba bag that I've owned and the design and quality are superb.

I ordered the Tenba Cooper 8 for an upcoming trip and don't like traveling with a large camera bag. When I got the bag I thought I had made a mistake - it's soooo small. I managed to get my Olympus EM1 with a 14 - 150mm 4 -5.6 mounted, Leica-Pany 25mm, and the Olympus 12-40mm into the bag - it was a little tight! I've only used this setup for a couple of weeks but have noticed with use that it gets easier to access the camera and I'm liking the bag a lot. I took the handle strap in the bag off for easier access.

The Tenba Cooper DSL Backup delivers as promised. The materials are top notch, the layop of the bag is excellent, and the size in perfect for air travel.

The Tenba Cooper 6 Messenger Bag is my new best friend of a camera bag. I always have a camera with me and this small bag fits me perfectly. I carry my Sony A1 camera on my arm with an extra lens or two along with an extra battery, lens cloth, notebook, and etc, as a norm in the bag. It is well made and tough, always ready for use and is very comfortable to carry along with it being extremely well made. This camera bag will always be in better shape than you at the end of a long day after working hard on a tough shoot where you had planned to travel light. The bag will have made it a wise decision.

I already have a Tenba Cooper DSLR Backpack, but purchased the Tenba Cooper Slim Backpack (Gray) for my Nikon Zf, and it has just the right amount of storage for the body, lenses, and accessories as advertised.
