Will it work? Is it safe?

As promised in a blog post on 12 October 2020, this is the first of several follow-up posts related to using the Anker PowerCore+ 26800 PD 45W battery as a power source for select Canon and Fujifilm digital cameras.

The power bank is one of two recommended by Fujifilm, so it’s reasonable to assume the battery is safe to use. That being said, I must admit I was hesitant to test the battery with a relatively expensive digital camera like my Fujifilm X-T3!

GyroVu” sells adapter cables that enable an external battery to be used as the power source for several makes and models of digital cameras. I recently ordered GyroVu adapter cables from B&H Photo for my Canon EOS 5D Mark II and Fujifilm X-T3. The following warning was included in the package for the Fujifilm adapter.

Specifications for proper operation.

Naturally I wondered whether the Anker battery meets the specifications to function properly with the GyroVu adapter cables. The specifications for the battery are printed on its textured case, in tiny letters that my tired old eyes are unable to see without using a magnifying glass!

Notice the specifications highlighted by the red rectangle superimposed on the full-size version of the preceding photo. [USB] Standard Output is 5V at 3A, within specs for the GyroVu adapter cables.

What are the take-aways?

Knowing the battery should work, and more importantly, should be safe to use, I was encouraged to test the battery as the power source for my Canon EOS 5D Mark II and Fujifilm X-T3 digital cameras. I’m pleased to report both cameras work as expected. More later in a series of follow-up blog posts.

WARNING

The B&H Photo Web page for the GyroVu USB to FUJIFILM NP-W126 Dummy Battery Intelligent Cable (40″) says the cable is compatible with Fujifilm X-T1 digital cameras (see the section entitled “Overview”). THAT’S INCORRECT! The page also says the cable “allows the use a USB power source to power devices that use a FUJIFILM NP-W126 battery.” THAT’S ALSO INCORRECT!

Fujifilm X-T1 digital cameras use an NP-W126 (7.2 V) battery; Fujifilm X-T3s use an NP-W126S (8.4 V) battery. The names for the two batteries are similar but similar is not the same, as indicated by the difference in their voltages.

The GyroVu Web page for the USB TO FUJIFILM (NP-W126S) BATTERY 40″ ADAPTER CABLE says the cable “Connects any power source with USB female connector to Fujinon Cameras using NP-W126S battery” and specifies the output voltage as 8.4 V. That means the GyroVU cable will work with Fujifilm X-T3 digital cameras and will not work with Fujifilm X-T1s.

Bottom line: I tested the GyroVu adapter cable (SKU: GV-USB-126S) and Bescor NP-W126S Dummy Battery & AC Adapter Kit for Select FUJIFILM X-Series Cameras with my Fujifilm X-T1 digital camera and the camera DOES NOT POWER ON. Buyer beware!

Post Update: Further testing shows an NP-126S battery can be used to power-on my Fujifilm X-T1. I cannot explain why the Fujifilm brand battery works and the GyroVu and Bescor power sources don’t.
