Choose a spare cell for quick swaps, a multi-slot charger for rotating batteries, or a bank or grip for added power away from a wall. Match the accessory to your camera, then add a close-fitting case or lens guard if protection is the priority.
Power choices by camera
Choose a spare cell when you want to swap batteries in the camera, a charging case when you rotate several spares, and a battery bank or grip when you want power away from a wall. Match the battery and accessory to the exact camera first:
- GoPro Hero 13: The Telesin rechargeable battery is a single spare cell. If you already carry several Hero 13 batteries, the triple-slot charger kit charges up to three at once.
- DJI Osmo Action 5 or 6: The three-slot charging case charges up to three compatible batteries and stores two TF cards. It is a charger and storage case, not a camera-mounted battery grip.
- DJI Action 6, 5 Pro, 4 or 3, and Osmo 360: The Portable Power Battery combines a 10,000mAh bank, two slots for the listed original DJI camera batteries and Type-C output for small USB devices.
- DJI Action 5 Pro, Action 4 or Osmo 360: The Portable Charging Handle puts a 5,000mAh battery in a grip that Telesin says can charge the camera while filming. It also adds a tripod, camera buttons and a fill light. Its compatible-camera list is narrower than the power bank’s, so check the exact model.

Cover and lens guards
The Telesin silicone case for the Osmo Action 6 adds a grippy cover with ports accessible. A UV protection filter guards the front lens of an Action 4 or 3, and the dual lens protection set covers both lenses of an Insta360 X5. For daily carry, see the mini carrying case.
In the water
A phone can go underwater in a rated case: the Telesin underwater diving phone case is rated IP68 to 20m with button controls. For action cameras, see our action camera accessories guide.

Frequently asked questions
How many batteries should I carry?
Carry enough spares for your longest shoot and use a multi-slot charger so you can top them up together.
Is a silicone case enough protection?
It guards against scratches, dust and light knocks, but it is not a waterproof or hard case.
Should I leave a UV filter on?
A UV filter is designed as a leave-on protective layer for the front lens, and it takes the scuffs instead of the lens.
Can I use my phone underwater?
Only in a rated case with button controls, and test the seal at the surface first.
