Has anyone considered totally portable charging for the MP?
Thinking of trekking a 1 week “off the grid” hike … so the solar panels would need to be moderately light in weight. Preferably something I could attach to the outside of my rucksack to charge using the brighter sun/light around the middle of the day.
Solar chargers for USB charging of the RC and phone/tablet have been about for a while … but the MP batteries offer a bigger problem.
There are car battery solar chargers that, to charge the car battery, need to provide a higher a voltage than the MP car charger’s required/annoying 13.4v (engine running) to function … so perhaps something like https://www.maplin.co.uk/p/maplin-15w-flex-solar-panel-n43en?cmpid=ppc%3Aall_products%3Apla%3Agoogle&gclid=EAIaIQobChMIlKjYyIWM2QIVLLftCh30NA-2EAQYASABEgJF6vD_BwE&gclsrc=aw.ds might work … but that’s a tad heavy at 1kg, but could be OK.
The MP car charger is compatible with 24v trucks … and that unit does “say” that its max output is 19.8v. That would definitely beat the MP car charger’s annoying minimum, but I wonder how bright it has to be to get above that magic 13.4v?
