Telesin Portable Power Battery for DJI Action and Osmo 360 Review

The Telesin Portable Power Battery solves a simple problem for action-camera shooters: the camera is still fine, but the spare batteries are not. It combines a two-slot charger for DJI camera batteries with a 10,000mAh power bank, so a day on a trail, a boat or a shoot can run on batteries you charge from the same compact unit. We recommend it for anyone who regularly shoots away from an outlet with a DJI Action camera or an Osmo 360, because it cuts a separate charger and a separate power bank down to one pouch item.

Two slots, one bank

Two independent camera-battery slots mean you can recharge a pair of spare batteries at the same time instead of cycling them through a single-slot charger. That suits the evening before a trip, a lunch break on a hike or a break between shots on location. A four-level LED indicator shows charging status, so you can see at a glance how much of the bank is left before you leave the bag.

The 10,000mAh internal battery also works as a normal Type-C power bank. It tops up smartphones, wireless earbuds and selfie lights. We like that it is one tool for two jobs, since the weight and cable clutter of separate accessories add up quickly on a long shoot.

Charging speed and capacity

18W PD fast charging takes two camera batteries from 76% to 100% in 1 hour 53 minutes, and the 10,000mAh capacity recharges camera batteries more than four times or a typical smartphone about twice. Those times are for that starting charge, so your exact time depends on the batteries you carry.

Compatibility is the first check

The slots are made for DJI Action 6, Action 5 Pro, Action 4, Action 3 and Osmo 360 original batteries. If your camera uses a different battery, the camera slots will not help, though the Type-C port still works as a general power bank. Confirm the battery model on your own camera before you order, especially if you carry more than one DJI camera.

Carry weight and travel

At 256g and 4.09 × 1.30 × 1.10 inches, the unit slips into a camera bag or a pocket, and the orange carry loop makes it easy to clip or grab. The capacity is built to meet major airline carry-on safety standards, which matters for travel. Rules for power banks vary by airline and country, so check your carrier’s current policy before you fly.

For other Telesin gear that suits the same kind of trip, see our Telesin 60m waterproof case review for the Osmo Action 6 and our Telesin 3m selfie stick review. Both pair well with a long day out with the same camera.

Buying recommendation

Choose the Telesin Portable Power Battery if you shoot with a listed DJI camera and are often away from a plug. Its two slots, 10,000mAh bank and pocket size are a strong match for hikes, travel days and long shoots. Skip it if your camera uses a different battery or you only need a small phone-sized bank.
