PowerBank? What we need to choose

In present day, we use electronic devices on day-to-day basis, such as our mobile phones, tablets. The problem with these so powerful devices we are using is that it consumes a lot of energy, and they could drain their own batteries in such a short time. Of course, without energy, these so smart, and so expensive de
vices are useless and worth as much as paperweights. So, power bank can serve this purpose perfectly. It could energize your devices back to life and prolong the usage of your devices for hours.


The question is 'how do you know which one is the right power bank for you?


SEE IT BEFORE BUY A POWER BANK
1. Your device battery size.
You can take note of this information from your package or search on the internet about your device.
Usually this information will be in battery section, which mentions the size of your device's battery.

2. Charger specifications.

Charger specification should located on usb adapter bundled with your device.The information we are looking for is the output voltage and output current of the adapter.





Buying a power bank.
1) The power ba nk we buy should have at least the same size as our device battery to ensure at least 1-full charge for your device.


2) The output voltage of the power bank should have output voltage and current equal or higher than your device's charger specification.

In addition to those two specification above, I recommend looking for power bank with addition charging cable and connector adapters, because it could help when you need charging other devices in unexpected situation.
