What It Is
A high‑capacity external USB battery (power bank) designed for photographers, videographers, and field creatives needing reliable, portable power. It supports dual USB outputs so you can charge or power two devices simultaneously (e.g. camera power systems, phones, tablets, USB accessories).

Powering the Case Relay Camera Power System so your camera can run continuously without battery swaps. Polyline Corp+1
Charging phones, tablets, and other USB accessories on location. Tether Tools+1
Supporting smaller devices like CamRanger, GoPro, external monitors etc., especially when AC power isn’t available. Polyline Corp+1
Gives substantial standby or usage time: for example, claimed ~ 50 hours of power for an iPhone 6; ~ 20 hours for an iPad Air 2. Polyline Corp+1
Limitations / Things to Consider
Because it’s 10,000 mAh and has a dual output, it adds some weight and bulk (~ 275g) — consider whether that fits in your travel/rig load. B&H Photo Video+1
Only has USB Type‑A outputs. If you need USB‑C PD or higher voltage outputs for certain gear, this might not suffice.
Recharge time is ~ 5‑6 hours — so plan ahead for downtime if depleted.
Output of 2.1 A is decent, but may not be enough for very high‑draw devices (power‑hungry cameras, continuous video, large monitors). Voltage drop, cable quality, and current requirement can impact performance.
Practical Tips for Use
Use good quality USB cables with low resistance to avoid voltage drop, especially if powering something like the Case Relay coupler or camera accessories.
Always carry a spare cable—sometimes cables fail before the battery does.
If using outdoors or in cold conditions, remember battery packs lose effectiveness; keep them warm when possible.
Use the protective silicone sleeve (available separately) to avoid scratches, provide grip, and protect against bumps.
