Hello derek.chan
Thank you for your inquiry.
But the ZU680KL can only support quick charge with the genuine charger that comes with the phone, thank you
Very disappointed it is lock to Asus Charger only. There are so many Qualcomm 2.0, 3.0 products, example I cannot buy a Fast Charger for Car or Power Bank for the ZenFone 3 Ultra.
Bought a AUKEY 16000mAh Portable Charger with Qualcomm Quick Charge 3.0
If I plug into charger that comes with phone, it shows Quick Charge... BUT with the Qualcomm 3.0 Power bank, apparently it DOES NOT show Quick Charge when I plug into the Qualcomm 3.0 Charge port.
Consolation is that the charging rate seems fast even though the phone does not show Quick Charge on the phone. The Apps AMPERE shows charging current at 1360 to 1450 mA charging...
So want to comment or still want me buy a Asus Battery Bank or Car Charger ?
Hey Derek
That is not true. You DO NOT have to buy an ASUS Charger to charger any of the Zenfone 3's. These guys work for ASUS so they want you to buy their products. This specifications page explicitly says it requires Quick Charge 3.0 with 18W of power to get BoostMaster Charging to work. https://www.asus.com/us/Phone/Ze ... 0KL/specifications/
The key is the 18W QC 3.0 spec. Ebay sells them. Run a search with "quick charge 3.0 18w charger".
