Ziron tactical replaceable battery power bank now crowdfunding

Ziron has started a crowdfunding campaign for its Tactical Power Bank on Kickstarter. At the time of writing, it has surpassed its $513 funding goal with around 30 backers.

The main feature of the Ziron Tactical Power Bank is its replaceable batteries, allowing the user to expand its capacity. It supports a single 21700, 20700, or 18650 battery with 5A discharge and 2A charge. For context, a 4-pack of 5,000 mAh 21700 rechargeable batteries costs $20-30 (Jesspow product curr. $23.77 at Amazon). The remaining battery level is indicated with integrated lights, and the battery is held in place with a snap-lock cap.

Ziron’s Tactical Power Bank has a single USB-C output for up to 30W fast charging. It has an aluminum alloy casing and is rated as IPX6 waterproof. It measures 8.5 x 5.5 cm (~3.34 x 2.16 inches) and weighs around 105 g (~3.7 oz), which would make it particularly light. Plus, its keychain design makes it easy to attach to a clip or a carabiner.

Backers can currently pledge $29 to the Kickstarter campaign to receive the Ziron modular power bank and various accessories. The company is shipping anywhere in the world, with deliveries estimated for December 2025. It is worth noting that, as with any crowdfunding campaign, there is no guarantee that backers will receive the product in the estimated delivery window, if at all. This is Ziron’s first Kickstarter project, which makes it a riskier campaign to back.
