Like most vehicles, the vehicle used to test charging does not like a steady raw of 90 watts for more than 10 minutes or so it cuts power to protect the battery. MPG needs more time in the field to use the BatPower charger, but so far it looks to be an outstanding choice for charging laptops and phones in the car. Thus one can charge two iPhones and a laptop all from one handy little device. In addition to the 90 watt laptop charging port, USB devices like the iPhone charge very quickly on the two high power USB-A ports. A little bit of A/C directed at the charger unit dispelled the heat quite well. That is what happens when high amperage goes through a wire-expected behavior. Indeed enough current was flowing (90 watts is about 7 amps) that the end pin on the BatPower as well as the socket of the outlet were quite hot (not burning hot, but hot).

The BatPower charger did become hot, but not overly so and it does not make any noise or otherwise show any issues. Actual charge rage is thus almost certainly higher than 47 watts per hour Heat * This of course averages out the bulk charge phase with the diminishing trickle charge phase as the laptop becomes nearly fully charged.

If power supply can supply 90 watts, that’s only 15 watts remaining to charge a depleted battery. For example, it is possible to use a MacBook Pro hard enough to draw 75 watts. It supports the idea that the BatPower performs as advertised or close to it, at least during the bulk charge phase with the computer sleeping.Ĭharge behavior and power draw could differ with active use. which is very close to the rated 90 watts. Going from 16% to 67% in 43 minutes is a gain of 51% of capacity or 39 watt hours in 43 minutes ~= 54 watt hours per hour for the bulk charge phase:ĥ4 watt hours/hour * 20 volts * / 12.4 volts = 87 watts

But since there is some power draw when sleeping and approaching 99% charge does not draw anywhere near the full charge current, the BatPower is probably drawing something closer to 90 watts in its bulk charging stage. This implies at least a DC input 12.4 volts = 71 watts (44*20/12.4). That equates to 44 watt hours per hour for a battery at 20 volts. With a 76 watt hour battery in the 2017 MacBook Pro, that charge rate suggests 63 watt hours in 86 minutes, or roughly 0.73 watt hours per minute. An iPhone was also connected and being used to listent to music, so there was additional draw from the iPhone while the MBP charged. Adding that up: 16% charge to 99% charge in 86 minutes*. Returning home (another 43 minutes), it went up to 99% charge. Charging over a 43 minute trip, the charge went from 16% to 67% in 43 minutes. MPG drained a 2017 MacBook Pro to 16% battery level. In both case, the the charging performance was impressive, with rapid gains in battery charge, just like a wall charger. MPG tested the BatPower charger in two vehicles. The design is well considered: one port on the BatPower charger, takes any of the three kinds of cables, thus making it a quite versatile charger should one have both USB-C and MagSafe Apple laptops-well done!īatPower Car Charger for MacBook Pro 2016/2017 with USB-C, and MagSafe model for 2011-2015 models In use Thus one could buy the USB-C version and then add the BatPower 5M2 Charging Cable for 2012 to 2015 Retina MBP MBA and MB to be able to charge a 2012-2015 MacBook Pro. The only difference between the two models seems to be the supplied cables, because the high power socket on the charger can accept all three cables interchangeably: a USB-C charger cable, 2012-2016 MagSafe Charger cable, or a 2011 and earlier MagSafe Cable.

There is also a version with cables for the 2015/2014/2013 MacBook Pro and earlier ones as well both cables are included, the BatPower CCA 110W Laptop Car Charger for Macbook Pro, MacBook Air and MacBook (2006-2015 Mac laptops) Charges a MacBook Pro at 90 watts (the maximum) BatPower Car Charger for MacBook/MacBook Pro
