Hi Everyone,
Quite a popular topic always which is always brought up is the lack of a USB charging capability for mavic drones. Perhaps DJI don’t want people whinging that their batteries take so long to charge.
However I believe to a lot of people, a USB charger for mavic batteries would provide quite a bit of utility, perfect for hiking with the drone. Personally I have 3 batteries as I got the flymore kit but additional batteries are around $200 AUD, quite expensive. The mavic 2 battery is around 60Wh and I can buy a xiaomi 20Ah powerbank (74Wh) for around $20 AUD, they are so cheap lol.
Given most people wouldn’t discharge their batteries below around 20% (50Wh of power needed), a 74Wh powerbank should almost be able to deliver a full charge taking into account boost converter efficiencies, Peukert's law etc. 26Ah powerbanks are also popular too. Imagine if it had a little Peukerts switch to control the rate of charge lol.
In terms of parts all you really need is a boost converter and charging circuit, I can’t believe no aftermarket companies have done his yet (hint hint).
It could be quite basic and just use a standard 5V, 2A usb output, or it could also make use of newer QC standard, like some of them can deliver up to 45W etc.
Since USB powerbanks and usb charging in general has really became an unofficial standard for all electronic devices it would be great if there was a product which could utilise all the ultra cheap high capacity powerbanks on the market.
My purpose in writing this is to get people talking about it more, and perhaps an engineer (with more time than me) may want to crowdfund this idea to create a product, or even a 3rd party charger manufacturer may want to steal it.
Technically it could be done and from $5 or so of parts you could easily sell it for around $50 at least.
Cheers
Michael
