Kessler, a company that specializes in accessories for filmmakers, has launched a new product called the Mag Max 3A, an adapter that works with select DeWalt power tool batteries for charging cameras, smartphones and certain other equipment. The adapter can be used with the DeWalt 20v Max and 60/20V Flex Volt models.

The adapter is quite unusual, but it's easy to see how some users may benefit from this arrangement. Power tool batteries are available at most hardware stores, are fairly affordable, compact and something many people already own.

Kessler explains the reason it launched this product, saying, 'The Mag Max 3A was developed to fill a void in the market for an inexpensive battery solution with a readily available common battery that can be found in almost every country in the world and at most hardware stores.'

The company selected DeWalt batteries for its adapter due to the brand's popularity in a variety of industries, according to Kessler, including filmmakers and audio recordists.

The Mag Max 3A adapter is capable of powering DSLR and mirrorless cameras, Kessler's motion control systems, LED accessory lights, monitors and other common gear that draw up to 3 amps of power. The device is made from high-grade aluminum, includes multiple 3/8-16 and 1/4-20 mounts, embedded neodymium magnets, as well as optional accessories that include a gold mount stud kit, V-lock kit and belt clip.

The Mag Max 3A adapter is available from Kessler now for $250, though it is currently discounted to $200. The DeWalt Flex Volt battery costs around $129 from most retailers, meanwhile, and the DeWalt 20V Max battery costs around $189.
