[ZenFone 2 Accessories] dasklney:
Our new smartphone is more powerful everyday, but we just can’t put a big battery in a small and slim device, so they invented PowerBank.

Tronsmart is one of the first manufacturer to introduce Quick charge 3.0 PowerBank, they named it “Presto”, it’s powered by 12000 mAh battery which can charge up to 4 times for our Zenfone 2. Sadly, this powe rbank supports QC 3.0 but our device can only charge with QC 2.0.

Tronsmart Presto Specifications:

Qualcomm Quick Charge 3.0: Up to 4x faster than standard chargers, able to charge compatible devices to 80% in just 35 minutes. Backwards compatible with all versions of Qualcomm Quick Charge.

Type-C Input and Output: Use it to quickly recharge the 12000mah external battery, or to power your Nexus 6p/5x with USB-C/Type-C ports.

Remarkably Compact: Much smaller than other high-capacity portable chargers. No other charger packs this many recharges at such high speed into such a small space.

Stylish, Practical & Safe: Smooth ebony varnish with 4-LED battery level indicator, 100% safe circuit protection; charger automatically shuts down if short circuit or overload occurs to protect your devices.

2. Tronsmart Presto Power Bank:

​

The power bank is made from all plastic, with black color and solid build. I really like this over Xiaomi Power Bank because the Mi Powerbank is easy to get dirty as there is a lot of dust in my place.

On the front of the Tronsmart Presto power bank, you will see a Tronsmart logo and 4 stylist battery level indicator white LED.
​

​

On the back, you will see some technical informations about the output and input of the power bank. Here is a closer look:
​

On the top, there are two port, the USB 3.0 port is for output only, but the USB-C port you can use it for both output and input (to charge your devices or to charge your powerbank).

​

The power bank comes with one 30cm length USB-C and USB 3.0 cable, the cable is solid too.
​

On the side, you can find the power button, you have to put it to power on the Tronsmart Presto before use (not like Mi Powerbank, you just put the device in and it will automatic charge your device!).

​

3. Charging Zenfone 2 with Tronsmart Presto.

I’m using Zenfone 2 with Anker cable to test Tronsmart Presto power because Zenfone 2 doesn’t support USB-C.
​

​

I started charge the device from 3%, and it took 10 minutes to charge from 3% to 17%.
​

​

I got 20% in 13 minutes. There is not much heat as QC 2.0 charger.
​

​

I got 41% in 29 minutes.

​

​

I got 58% in 42 minutes.
​

​

I got 79% in 1 hours and 2 minutes, the phone is now charging at normal mode to extend the battery life.
​

​

I got 89% in 1 hours and 16 minutes.
​

​

The phone is now fully charged at 1 hours and 48 minutes.
