Rather, it is class with her black dress and matt prevents it from getting dirty quickly (farewell fingerprints). It consists on a fantastic grip and feels good in our palms with a well thought out ergonomics, its average size and rounded edges and seized.
It may seem rather heavy but with 185 g, it is lighter than other reference external batteries, including 10400mAh Genuine Xiaomi.
A hole location hosts a lanyard (not supplied) to hang the PowerPack to a bag or key ring.
To charge the battery T7800: it is connected to a computer or USB charger universal preferably high power (> 2 A) to reduce the charging time via the Micro USB cable.
To charge a USB device is connected the cable to the device (micro USB side) to the battery (standard USB side). The battery goes out automatically after 1 minute 30 if no device plugged nest.
You can charge 2 devices simultaneously thanks to the 2 USB ports. Port A delivers 1A (moderate to little power hungry devices such as MP3 players or less powerful smartphones) and the second port sends 2.4A (recommended for energy-hungry devices such as the latest models of Android and Apple smartphones).
The choice to offer 2 different power ports is useful because batteries tend to suser faster if they are charged with a higher power level than needed. Go through the Port 1A therefore increase the life of the battery of small appliances.
4 blue LED diodes are used to verify the remaining load capacity:
- 4 LED displays: 75 to 100%
- 3 LEDs: 50 to 75%
- 2 LEDs: 25 to 50%
- 1 single diode: between 0 and 25%
The current capacity can be determined by briefly pressing the button on the front facade.
*** TEST ***
By using the fast port 2.4 A, it took me 3:05 to go from 15% to 100% load with my Nexus tablet in July 2013 rather energy. For this kind dappareils greedy, an external battery is highly recommended if you are traveling or away dune electrical outlet.
At the end of this procedure, a single blinking LED on the external battery. This suggests that the capacity of the battery allows it to recharge quun only greedy device.
*** MY OPINION ****
The PNY PowerPack T7800 is a friendly and interesting battery to charge 1 or 2 devices simultaneously. However, if you are often on the move and want repeated charging your device, I recommend you rather opt for higher models mA and 8800 mA 10400, offering a greater capacity to recharge.
