Allpowers 16AWG Adapter Cable

The Allpowers 16AWG adapter cable solves a simple but common problem: a solar panel wired with MC4 connectors has no way to plug into a power station that only accepts a DC barrel jack. This cable bridges the two. One end carries a male and female MC4 pair that clips directly onto a panel's leads; the other ends in a 5.5 x 2.1mm DC plug, with a 3.5 x 1.35mm adapter included for stations that use the smaller barrel size.

At 1.5 meters and 16AWG copper, it gives enough reach to position a panel a few steps from the station without a second extension, while staying thick enough to carry a panel's full current with minimal loss. It works with any power station that has a built in MPPT charge controller and a compatible DC input, which covers most portable stations on the market today.

On the US market, the exact same Allpowers cable is confirmed sold from the brand's own US warehouse, at $19.99, though it currently shows as out of stock there and on its Amazon.com listing as well. Real Amazon buyers, reviewing this cable since 2022, describe it as doing the job for most solar setups, while a handful flag the wiring gauge as thinner than expected or note a missing adapter in the box, worth checking against your own station before relying on this cable exclusively.

Simple and inexpensive, this cable remains the accessory that is easy to forget when buying a panel and a power station separately, and the one that turns two incompatible connectors into a working solar setup.
