TurboPower

We all want our smartphone to charge quickly. And different phone manufacturers have either created their own propriety method of charging (Oppo VOOC or MediaTek PumpExpress+ or Motorola's TurboPower or OnePlus's Dash) or have opted to comply with a industry wide standard like Qualcomm's Quick Charge series of standards).
These technology work my allowing a phone to tell the charger to step up the voltage beyond 5 volts so that the power available to the phone for charging the battery is more than what a good 5 volt / 2 ampere wall/car charger can supply.

I have a Moto G4 plus and I wanted to make sure that I had access to fast charging at home/office, in car or while travelling. So I went ahead and got the following accessories

Voltmeter

USB Voltmeter Stick

  • This small device is what allowed me to check at what voltage/current the various chargers were charging my phone or regular devices.
  • It has a USB male and female receptacle so that it can sit between the charger and the USB cable.
  • It shows the voltage, current as well total mAh consumed during the past few hours - all these 4 parameters are shown on its OLED display. It ofcourse discounts the current it itself requires.
  • A reset button will allow you to reset the energy and time counter - The energy and time counters are stored in its non volatile memory and their values are preserved across power cycles so you need to reset them manually.
  • ₹777.00 at Amazon.in

Wall Charger
  • Comes in the box when you buy your phone
  • There re two varieties of these chargers - one has a USB female socket in it and comes with a  detachable microUSB cable while others have microUSB cable connected to it permanently. I have both of these but prefer the one with USB female socket
  • When I used the voltmeter to investigate the charger I discovered the following:
    • It charges regular devices at 5.0 volts
    • It charges Moto G4 plus and Moto G5s plus at around 9.0 volts
    • It charges Qualcomm QC 3.0 compatible devices at around 11.5 volts
  • Thankfully, its 2 pin has the correct diameter and distance between them to fit snugly in Indian AC main sockets - unlike those sad chargers which have europlugs which hang loosely when used with Indian sockets.
  • ₹1,364.00 at Amazon.in

Car Charger
  • This charger is small and compact and is an original Motorola accessory which is bought separately.
  • Supports QC 2.0 devices (Qualcomm QuickCharge)
  • When I used the voltmeter to investigate the charger I discovered the following:
    • It charges regular devices at 5.0 volts
    • It charges Moto G4 plus and Moto G5s plus at around 9.0 volts
    • It charges Qualcomm QC 3.0 compatible devices at around 11.5 volts
  • ₹990.00 at Amazon.in

LCARE Qualcomm QC 3.0 Quick Charge Power Bank


  • Now that I had charger for fixed sockets (Car and AC Mains) I wanted a portable power bank with fast charging technology as well. Motorola's TurboPower seemed compatible with QC 2.0/3.0 so I tried this particular powerbank and was pleasantly surprised.
  • When I used the voltmeter to investigate the charger I discovered the following:
    • It charges regular devices at 5.0 volts
    • It charges Moto G4 plus and Moto G5s plus at around 9.0 volts
  • The QC 3.0 technology is used in input as well as output sides. i.e. when you try to charge the power bank itself using any of motorola's original accessory - the car charger and the wall charger - you notice that those chargers themselves are able to charge the powerbank at around 11.5 volts - so basically you have a power bank that not only charges other devices quickly, but also itself gets charged quickly.
  • A backlit LCD display shows the charge level remaining in percentage numbers and also shows the charging technology being used
  • One downside - the powerbank cannot charge mobile devices when it is itself being charged.
