Fashionable Portable Power Bank

How to calculate the conversion rate of power bank?

The formula is: battery capacity * 0.8 (about 20% loss) / mobile phone battery capacity = charging times (approximately). For example, a usb external backup battery with my 1440 mAH, Power bank capacity 5000mAH. The formula is: 5000mAH * 0.8 / 1440mAH = 2.7 (approximately). Some mobile phone factory manufacture of the mobile phone battery, original battery also has the performance loss when charge, was estimated as 10%, if the loss of effective account. Such as the original phone battery performance loss: 5000mAH*0.8*0.9/1440mAH=2.5 times(approximately).

It is funny when you get a product that before receiving it, you never knew how much you needed it. That is the case with the Magic Cube I received from Powerocks. To be honest, I did not even know what a portable power bank was until I received my little pink rectangular cube of awesomeness. The timing on the arrival of the Magic Cube could not have been better. My husband spilled soda on the car charger for our phones and he depends on that thing to keep his phone going. The day after he did this, the Magic Cube came and I had been playing with it when he came home from work. He took it with him ti work the next day and he was so excited about it! I am so not surprised that the products from Powerocks has won awards like the Family Choice Award, Best In Children’s and Parenting Products for Highest Capacity.
