PROS
Good Quality 7 Segment Display
CONS
Voltage/Percent Calibration is wrong
Charger is of Good Quality at the first look. I have installed 18650 from panasonic 3400 Capacity. At the voltage level of 3.45 Volt (2.75-4.20 is the limit for lithium batteries) so 3.45 is 48-50% but the charger shows 15% remaining. So that bug. they have not given any calibration how to calibrate the voltage display or percentage display in order to get correct capacity of the batteries. After charing 2 time my sony xperia Z1 it empty showingr 000 and switched off. When i look for battery voltage its 3.45 menas 50% of the charge is available and it shows 0%. So company and Fasttech should consider this as an enhancement request and provide better quality products to customer so they dont have any future problem like this. I am Technical person so i can check everything, but for no-wise users it hard to commit that hardware is faulty and they will end-up saying batteries are faulty.

PROS
-2A Continuous Current Operation -Light Weigh Compact -supports 4*18650 -Battery level indicator -Battery Charging Indicator
CONS
-Back cover is loose. -No screws Provided for fitting back case.
This is one of the best and great for using your 18650 as power bank. It has nice inbuilt circuitry to protect your 18650 from over charging and discharging and also providing constant output of 2.06 Ampere with 0.47 Ohm Resistance Load, checked with Voltmeter/Ammeter.
