Take a gander at the pins. The pins are same start to finish in the copy charger. In the first charger, the Pins are thicker in the lower parcel towards the base.
All USB ropes convey the equivalent 5V, paying little mind to if it has a 30-pin head or a microUSB plug, regardless of whether it's first-gathering or third. ... Since they have predictable, normalized voltage, USB chargers need another methods for putting more force (regarding watts) into bigger contraptions quicker.
The most effective method to Test a Battery Charger. In case you're uncertain whether your battery charger is working appropriately, there's a simple method to discover. Running a test on your battery charger is a simple cycle.
Stage 1
Plug in your charger to an electrical outlet. Eliminate any batteries you may have charging in the unit.
Stage 2
Turn on your voltmeter unit. Make certain there's capacity getting to the meter. Plug in the test tests into the voltmeter as indicated by the meter's guidelines. Set the selector change to the most elevated level for DC Volt or whatever is suggested in the meter's guidelines.
Stage 3
Take a battery or battery pack that is viable to your battery charger. Ensure the battery has no consumption and isn't releasing liquid. Contact the positive finish of the battery with the red test. Step through the dark exam test and spot it on the negative side of the battery.
Stage 4
Check the readout on the voltmeter and see where the pointer is demonstrating to. On the off chance that it's on the left side, or negative side, switch the test tests. On the off chance that it's on the correct side, it will show that the battery is accepting some charge. Where it focuses to on the meter will decide how much charge it got.
Stage 5
Check the battery charger to perceive how much force it's radiating, on the off chance that you keep on accepting a negative perusing from the batteries. A negative perusing will demonstrate an awful battery charger, and you ought to supplant it. On the off chance that the charger has adequate measure of intensity moving through it, it's without a doubt the batteries are terrible and just won't hold a charge.
