Regular charger vs Turbo charger

Patron asked me if it is OK to use regular charger with new Quick charge Android phone:  Yes

There are several types of rapid phone chargers. Some work by feeding the phone at a higher voltage (9 volts instead of the 5 volts put out by standard USB chargers). Others, such as the DASH system used by the OnePlus 3 smartphone in our ratings, keep the voltage at 5V but raise the amperage (4A vs. 2A for standard phone chargers).

But although the new phone chargers are built for speed, they default to a slower charging setting that's safe for all smartphones (5 volts at 500mA to 2A) when they sense they've been plugged into an unsupported device.

Qualcomm, which is known for its Snapdragon smartphone processors, is also behind the rapid-charging Quick Charge tech found in more than 100 smartphone models, including flagship phones from Samsung, Motorola, HTC, and others. (On some Motorola smartphones, Quick Charge is branded Turbo Charge.)

“There’s a lot of intelligence built into the charging process, with algorithms that help the adapter determine what the phone can take,” says Geoff Gordon, a marketing manager at the company.

It doesn't matter if that phone charger’s amp rating is higher than the one shown in your phone battery’s specs. The phone takes only the current it can handle. Consequently, when you plug a fast-charging phone into a conventional phone charger, it will charge at a slower rate.  

Onboard microprocessors monitor and manage the battery’s state of charge and health to ensure that they get what they need at a rate they can handle. And that works across ecosystems. In other words, it makes no difference that iPhones use Apple’s lightning connector and Android phones use micro USB or the new USB Type-C connectors. If you plug the cable that came with your phone into the USB port of any phone charger, it should work safely.
