The M6D delivers a total of 500 watts / 25 amps for about $65. Compare that to the ISDT Q6, which costs the same, but only outputs 300 watts / 8 amps. But the M6D has another trick up its sleeve: it’s got dual output channels. You can charge two different batteries at the same time! In addition, it’s got a 2.1A USB charging port so you can top up your phone while you’re topping up your packs.
The main thing that makes the M6D stand out to me is its small size. This could be the ultimate field charger. At home, you get 500 watts of power from your AC power supply. Toss it in your flight bag and run it off your car battery in the field, without adding a lot of weight. If you’re looking for a travel charger with built in AC power supply, check the next section of this website, below.
The precursor to the M6D, the M8, was also a great value for money, but it had some quality control issues, such as over-charging batteries, or just plain dying for no reason. That’s why I held off adding the M6D to my site until I personally tested it for a few months. I can’t promise you what the future holds for this unit, but so far I haven’t had any issues with it. And many people will feel that the value of this unit is worth taking the risk that the quality might disappoint them. In six months or so, I’ll update this listing to reflect people’s experience with this charger. For now, we can’t know for sure.
If you’re looking for a charger with a proven track record of durability, the HOTA / Hobbymate D6 (also on this page) has been bulletproof since it was released. It has higher output power than the M6D, and can be ordered both with and without a built-in power supply, depending on your needs.
