Retra Power Vault Features

Safety First

Safety is the most important aspect of the new Retra Power Vault. The compact all-in-one solution, enclosed in a fireproof aluminum shell with an integrated safety release valve designed to contain the energy of the Li-ion batteries in case of any accidents. 

USB-C Charging

Charging the Retra Power Vault is fast and easy. By integrating all the necessary electronics within the fireproof shell, charging is as simple as attaching a USB-C cable—no proprietary chargers or special connectors are required. 

Outstanding Autonomy

Recycle time improves by over 10% and battery life doubles compared to the 8xAA setup, providing up to 2,000 shots at 50% power and 1,000 shots at full power, for the Retra Flash Pro Max, with consistent recycle times regardless of battery charge.

Exchange the Cells, Keep the Shell

Life-time Exchange Service Guaranteed

While battery packs offer a lot of power, they have one major flaw. Traditionally, when a battery pack stops working or a new version comes along, the manufacturers usually don’t make or support the older versions anymore and as such, your old battery pack eventually becomes trash.

But not anymore! We've designed the Retra Power Vault in a way that enables us to guarantee a lifetime of battery renewals. This means that whenever the batteries reach the end of their life-cycle, you will be able to send the Power Vault back to us for an exchange of batteries (service and shipping costs apply).

The old batteries are then sent to a state-of-the-art battery recycling plant to ensure minimal (near zero) pollution.

By choosing the Retra Power Vault, you’re not just opting for superior performance and safety; you’re also making a choice to support our planet by conserving energy and resources, reducing waste and helping protect our precious oceans.

Help our planet and oceans by conserving energy and resources with the brand new Retra Power Vault.
