5000 mAh GP Portable Power Bank (FP05M) Test

12 Mar

The company GP Batteries is a pretty old and popular name when talking about batteries, but they also started making power banks with the advent of this new product category and they already have a umber of products available. Here we are testing one of their smaller capacity models – the 5000 mAh GP Portable Power Bank (FP05M) that looks and feels nice in terms of design and functionality and specs wise seems promising. It has an aluminum body, a convenient LED indicator for remaining capacity and support for 2.0A charging input and 2.1A charging output.

5000 mAh GP Portable Power Bank (FP05M) Specifications:
– Battery Type: Li-Polymer battery 3.7V 5000mAh
– Input current: 2A
– Output current: 2.1A
– Number of outputs: 1
– Size: 120 x 66 x 13 mm
– Weight: 165 grams (approx.)
– Operation Temperature: 5C ~ 40C
– Recharging time: 5 hours (approx.)


With the 5000 mAh GP Portable Power Bank (FP05M) we have performed our usual 1.0A and 2.1A constant current load tests and you can see the results on the discharge graph above. It is interesting to note the interesting jagged pattern of the discharge cure for both currents we have tested with the electronics of the power bank apparently trying to keep the output voltage closer to the 5V, so the output Wattage would not drop more even though the mAh capacity might still seem higher as we have seen on some other products. We are seeing good results under 1.0A and especially good under 2.1A load for a 5000 mAh power bank, so good job for GP Batteries for this device.

The performance of the 5000 mAh GP Portable Power Bank in our tests:

– 3023 mAh at 1.0A load
– 2896 mAh at 2.1A load

– 15.05 Wh at 1.0A load
– 14.02 Wh at 2.1A load
