Choose the brand of the 18V (20V MAX) batteries you already own. Each Volt product is made with a brand-specific mount, so it slides straight on like a tool. Pick your brand on the product page and it arrives with the right mount. Batteries are not included.

Yes. Brands like DeWalt and Black & Decker label their 18V batteries as "20V MAX" in some markets. If your battery is from an 18V or 20V MAX cordless tool line, the matching variant fits.

DeWalt FlexVolt 54V packs switch to 18/20V on these mounts, so pick DeWalt. Bosch Professional (GBA) is the blue range and Bosch DIY (PBA) is the green range, so check the label on your battery. WORX comes in 4-pin and 5-pin versions: count the contacts on the battery. Still unsure? Send us a photo and we will confirm before you order.

As a guide, one healthy 5Ah battery runs a 40L 12V fridge for around 5 to 7 hours. Add a second battery with the Double Battery Adapter for a full day. Real runtime depends on fridge size, temperature and battery health, so try the runtime calculator for your exact setup.

No. Built-in low-voltage cut-off stops the output before your battery drains to a damaging level. Over-current, short-circuit and thermal protection are built in too.

The cut-off trips before your battery reaches a damaging level. Put the battery back on your normal charger. The Volt Dropper resets when you remove and reattach the battery.

The cigarette socket suits most fridges and accessories out of the box. Anderson is the more secure, higher-current connector common on 4WD and camping setups. "Both" gives you the two outputs on one unit.

Yes. The Volt Dropper outputs 5 to 13V DC, set with a dial and shown on a live LED readout, at up to 10A continuous.
