the TP charge is rated 2A and can charge many devices if not all at the
highest currency the device can take.
Not every high currency charger on the market can fast charge your device.
for example only the OEM charger and this tp charger can charge my Samsung
Note at 1A currency. All the other chargers charge at 500mA, regardless of
the rating of the charger. Only the chargers that shorts the two data pins
of the USB port can do fast charging.
