Poor Charging ability, it appears that the "charge rate" is not as good as with the "equivalent mains charger" that is also 65W.
SO since its powered by the car Battery/Car Alternator (work truck - big diesel - has TWIN Alternators and can supply enough capacity to run a full house if needed!!
Thus the"input" power is not the issue here, then only thing left is the "CHARGER ITSELF">
We also have a similar charger (non-Lenovo unit) that works at charging our NEW X1 THINK PAD gen 6 Machines. We only going by what time it takes from " battery low alarm" to FULLY CHARGE STATE.... to compare units.

[This review was collected as part of a promotion.] Product meets all of my expectations. Both the cigarette plug and the transformer are small and do not take up much space. The cable is long enough, I could see how people might want a longer cable.
[This review was collected as part of a promotion.] This this the perfect accessory for on the go laptops and tablets with USB-C power ports. I've noticed it doesn't really charge while the laptop is being heavily used but it keeps it from decreasing in battery power. However when the laptop is off it seems to charge fine but is a little slower than the AC adapter. Still if you do lots of work from your car or truck this is a must and performs flawlessly!
I would recommend this to a friend!

[This review was collected as part of a promotion.] I needed something that was compatible with my Lenovo laptop. Verified that it was compatible and made the purchase. I am on the road 8hrs or more and need something to maintain my laptop charged.
[This review was collected as part of a promotion.] Excellent USB-C Travel Adapter for my Lenovo Thinkpad. Works flawlessly. Better than an invertor and using the standard 110 volt cord.
