Hi jassi, nice idea, I used solar panels and powerbanks in my several days travels where no electricity was available, but you have to check also the output current your powerbank can deliver through the DC 12V outlet. For the Mavic air you need at least 6A to charge both battery and RC and, at least 4,7A to charge only the battery. There are few powerbanks these days able to be solar charged and to deliver also high ampere charging currents (Litionite is one of those, if someone needs, I'll provide more brand / model names). I write this because I already burned a powerbank until I learned this lesson. Apparently the powerbank works but after a couple of cycles, the diode internal circuitry will be burned because most of them are designed to deliver high currents for short times (seconds), this being their main initial purpose (as car jump starters) and not for continuous delivery of high currents.IMO, this one https://www.amazon.com/Poweradd-Pilot-23000mAh-External-Smartphones/dp/B015OAJFOC/ref=pd_sbs_107_5?_encoding=UTF8&pd_rd_i=B015OAJFOC&pd_rd_r=7SEX1SXMPZXGE8C8ERT6&pd_rd_w=jwpEK&pd_rd_wg=CoeQR&psc=1&refRID=7SEX1SXMPZXGE8C8ERT6 has a quite limited current output, 4.5 A being not enough.
Another thing I learned and experienced is many powerbanks sold today are misinforming the consumers with higher capacities (mAh) than the real ones. For instance I opened a Floureon Ghero 01, claiming for 16800 mAh (and 300 to 600A through the car jumper port) and found the internal batteries pack consisting of 3 Li batteries of 11,1 V and 3200 mAh...(3 serial 3,7V cells).
For the people interested in such solution, suggest to avoid sparing a few pennies, buy a 90Wh powerbank as, its real power is less and also allows you to check it aboard when flying (recall power limit 100Wh per battery).
Will this one work? You seem like you know about these. Was going to get this for my Mavic Pro. https://www.amazon.com/dp/B01HEV ... ef_=lv_ov_lig_dp_it |
