I recently received a GOOLOO Quank 4500 mAh Quick charge External Battery Charger ( model GF02 ) for a product review. In addition to the battery bank itself, it also includes a cable to charge in the car and a USB to microUSB cable.

Charger and cables

The battery pack is rated at 4500 mAh, so I used my USB meter and 2A load to measure the capacity.  Based on the measured capacity, this pack put out about 77% of the rated capacity which is actually the highest I have tested so far.

To test the quick charging ability, I fully discharged the battery pack and then charged it in the car for a total of 30 minutes ( two 15 minute sessions ).  After that, I measured the capacity again using the USB meter and based on quick calculations it seems the battery took 80% charge in 30 minutes.  The product claims full charge in 30 minutes, but even 80% in just 30 minutes is impressive and it is possible my charging method ( two 15 minute sessions ) had an impact.   The battery pack was showing 4 LEDs of power, which is 80% so the numbers seem right.

Here are the main points I noticed about this product:

2A Output: The battery pack was able to handle a 2A load, so charging smartphones and tablets shouldn’t be a problem.  Both my 5” smartphone and 7” tablet charge at a rate less than 2A, so you probably would not hit the max 2A unless you had a large tablet.

Quick Charge: Using the car charger, the battery pack was able to charge at a much higher rate than it would have using a standard wall charger which is a great feature and I haven’t seen it on many units.

Other features: The battery pack has a nice design, and a built-in LED flashlight which I find useful.  It also uses 5 LEDs to show charge level, but they aren’t so bright that they would be annoying if you are charging the pack at night.

Bottom line: If you are looking for a battery bank with good capacity and quick-charge ability in the car, this is a great option to consider.
