TurboPower adapters come in three flavors: TurboPower 15, TurboPower 25, and TurboPower 30. The fastest, TurboPower 30, delivers 5V and up to 5.7A for roughly 28.5W of power. Every Google Pixel phone, from the original to the Pixel 4a, is capable of fast wired charging up to 18W using the USB-PD standard. It doesn’t require any special chargers or cables. Waze is a free, ad-supported interactive navigation app owned by Google and available for both iOS and Android. It uses your smartphone's GPS service to calculate routes between destinations and gathers information via social media-based crowdsourcing to alert you to road conditions while you drive. Drivers on the Waze platform act as the road's eyes and ears to alert other drivers about traffic, police, accidents, detours, speed traps, construction, and anything happening nearby or on your route. Reconnect the charger and data cable and try again. If you insert the cable into the phone too slowly or have not connected them properly, fast charging may not work. Use the car charger with a standard charging cable and a phone supporting 50 W wireless charging. Data comes from Huawei lab tests.

A Pixel phone can charge rapidly from 0% up to around 80% but will slow down beyond that point. You’ll find the same limitations with most phones. Standard Huawei data cable or a data cable that supports fast charging or super fast charging. To charge your phone with SuperCharge, a cable with 5 A or higher current capacity is needed. Apple iPhones from the iPhone 8 through the iPhone 12 models implement USB-PD, the same industry standard used by the iPad Pro, the 12-inch MacBook, Google’s Chromebook Pixel, and Lenovo’s X1 Carbon. Intercompatibility is its biggest advantage — USB-PD doesn’t require any special cables or wall adapters.In non-rechargeable batteries, those chemical reactions occur only once. But in the rechargeable lithium-ion batteries that power smartphones, the reactions are “reversible.” When the battery discharges, the chemical reaction produces electricity, and when the battery recharges, the chemical reactions absorb power. Fast charging

After a charger is inserted, it will take about 10 seconds for your phone to detect the charger and then start charging with fast charging or SuperCharge. This is normal and please do not be concerned.For example, 5 V/4.5 A Huawei SuperCharge requires a data cable supporting a current of 5 A or above (non-standard data cable may not be identified), and the impedance of the data cable should meet the SuperCharge requirements. If the port has dirt or smudges on it, clean the port in a timely manner. (You can use a clean soft brush or use an alcohol liquid cleaner if possible.) So we’ve established how batteries charge and discharge. But to understand how fast charging works, you have to know a bit about something called a charge controller.
