![]() ![]() ![]() This setup allowed us to finely control the power flow and determine whether it matched the advertised rate. Chargers with USB-A ports: We tested the maximum power draw from each port by plugging in a variable power load and an ammeter.We used the Total Phase USB Power Delivery Analyzer and its Data Center Software to measure and record this data, including the advertised power profiles, the steady state output, and whether any errors occurred in charging. Chargers with USB-C ports: USB-C uses digital communication between devices to verify charging speeds in a way that USB-A doesn’t with the right tools, you can interpret exactly what’s going on in the communication between the charger and the device you’ve plugged in.USB-A ports with 12-watt or QuickCharge 3.0 output: There’s no reason to choose a charger with USB-A ports slower than 12 watts (5 volts, 2.4 amps), because they’re not much less expensive and they offer slower charging to Apple and Android devices.Apple’s MagSafe wireless charger requires 20 watts in order to achieve its full wireless charging speed. But your device will pull only as much power as it’s rated for, so there’s no safety concern about your phone being damaged or overheating when you’re using a more-powerful charger. Phones that support USB Power Delivery (USB PD)-the standard that allows for fast charging over USB-C-generally draw as much as 18 watts, while larger devices can take 45 watts or more. USB-C ports with 18- to 45-watt output: A USB-C port charges most modern phones faster than a USB-A port does (if you’re using the right cable), and it can even charge tablets and laptops.It’s almost always a better value to choose a charger with two or more ports, whether those ports be USB-A, USB-C, or a combination of the two. At least two USB ports: The cost and space savings of a single-port charger aren’t significant enough to justify the limited output.-The solar battery charger panel mounts easily to the windshield or dash and conveniently plugs into your car's 12 volt cigarette lighter!
