Review on ⚡️ Anker PowerDrive Speed+ Duo, USB C Car Charger with 2 Ports - 30W Power Delivery for iPhone Xs/Max/XR/X/8, iPad Pro, MacBook Pro/Air 2018, Galaxy S10/S9/S8, LG, and More by Peter Nobles

Basically I started buying Anker products for all my aftermarket needs. From their car chargers to wireless chargers, cables, standard chargers and batteries. I've never had a single crash, quality issue, or performance issue. This is just another great Anker product. I tested it last night and I got the claimed charge capacity on my iPhone XS Max. Please note that you need an Apple certified Type-C to Lightning power cable. No other cable I found works. If you are testing the capacity performance on your iOS device, you should follow the instructions. The phone should be between 50-70% to get the most accurate estimate possible. Otherwise you will not get accurate results. Also note that speeds can vary wildly as the iOS testing methodology is different as it doesn't have direct access to the metrics it's trying to count.
