Part 2 - Car Charging the Inspire 2 - IRCTek DC Step-Up Converter

Today we're talking about DC-DC vs. AC Inverter charging for the DJI Inspire 2.
We used the IRCTek Inspire 2 Car Charger, a cheap $28 CAD instead of DJI's $140 CAD charger that outputs less than HALF the amperage.
Inspire 2 TB50 Battery Pairs:
DC-DC: 18% charged 13.21v - 12.43v = 0.78v = 28.8% of Yellowtop 55Ah Capacity
AC-DC: 24% charged: 13.20v - 12.39v = 0.81v = 30.0% of Yellowtop 55Ah Capacity
The AC Inverter setup used 4% more power, charging a slightly less drained pair of TB50s. The difference in the scheme of the Yellowtop's total capacity was only around 1% of its total Amp-hours.
I suspect the heat loss from the IRCTek chargers is what's making them as inefficient as the AC inverter, which I paid good money for and trust to be moderately efficient for the job performed.
IRCTek's car charger gets THREE STARS ⭐️⭐️⭐️ out of five, only because they perform as expected (albeit with occasional risk of empyrosis), the indicator light is nice, and their customer service is painless. They refunded these chargers when I contacted them with complaints of excessive heat.
