| Review of Bolse 3.1 Amp Car charger |
I own several car chargers and ran the same set on tests on each of them to provide unbiased results as the numbers speak for the performance of the unit.
To test Bolse car charger I ran my 10 minute test for each of my 3 devices on each of the 2 ports for a total of 6 tests. I repeated the same tests with a data cable and with a charging cable. The results of these 12 tests are included in the tables below.
I am attaching a collage of 4 photos labeled with numbers 1 through 4 under customer photos that I will be referencing in this review. You can locate this photo by following 'customer photos' link under the main photo.
Photo #1 shows the charger on a gridded mat next a pen for size reference. The car charger is 3.5" long. The charger's face is 1.25" by 1".
Photo #2 and #3 show how the charger fits into our two cars. It has a relatively log neck and fits very well in both car configurations. It goes in firmly, forms a good contact, and stays plugged in well even over rough roads. The charger has two outlets labelled 1.0 AMP and 2.1 AMP.
Photo #3 shows one of the tables during the testing. I use Battery App by Elvison to determine how each device recognized the charging source. 'AC' status means the charging is at full charging rate. 'USB' status indicates charging at a lower charging rate. 'Discharging' status means that the charging rate is below the power that the device is consuming so it slows down the discharge rate but does not re-charge.
My methodology is to charge each mobile device on each port of the unit for 10 minutes and measuring how much each unit was charge in that 10 minute period. Each line in the table below represents a separate 10 minute test
The key findings:
(1) Samsung Galaxy 7.7 cannot be charged with this car charger with either port
(2) Both Nexus phone and Nexus 7 tablet running Jelly Bean 4.21 charged at AC rate on both ports.
The table below summarizes my findings:
Nexus 7 Tablet
--------------
1 AMP port.......AC rate.....1% charge increase (data cable)
2.1 AMP port.....AC rate.....1% charge increase (data cable)
1 AMP port.......AC rate.....1% charge increase (charging cable)
2.1 AMP port.....AC rate.....2% charge increase (charging cable)
Samsung Galaxy Nexus Phone
--------------------------
1 AMP port.......AC rate.....2% charge increase (data cable)
2.1 AMP port.....AC rate.....3% charge increase (data cable)
1 AMP port.......AC rate.....4% charge increase (charging cable)
2.1 AMP port.....AC rate.....3% charge increase (charging cable)
Samsung Galaxy Tablet 7.7
--------------------------
1 AMP port.......AC rate.....discharging (data cable)
2.1 AMP port.....AC rate.....discharging (data cable)
1 AMP port.......AC rate.....discharging (charging cable)
2.1 AMP port.....AC rate.....discharging (charging cable)
I received this car charger from the manufacture for an honest review be it positive or negative. Running the same set of test on all the chargers I own allows me to provide an unbiased review. By comparing the results of the tests for chis charger to the other car chargers I tested, this car charger earned a 5 star rating. The only thing this charger did not do well is handle my Samsung tablet. However neither did other generic car chargers, Samsung tablet only works well with the car charger made by Samsung.
