Here's what other sellers of Power Banks don't want you to know: all power  banks store electricity at 3.7V, yet to charge a phone or any other USB device, you need a voltage of  5V. To step up the voltage from 3.7V - 5V is an increase of over 35%, meaning that at 5V your power  bank effectively supplies 35% less energy than what's stored at 3.7V - this is before conversion losses!   Our Smart Power Bank is a high quality, high efficiency device. Operating at over 92% efficiency means it will lose less than 8% capacity to heat. Some poor quality, cheap power banks can lose 40% or more of their stored capacity as heat! Furthermore, if the price seems too good to be true, the general rule of  thumb applies - it probably is! Low quality power banks commonly overstate the capacity by anywhere from 100-200%!   Many people think that their phone's battery is say 1,500mAh, so an 8,000mAh Power Bank should be able to charge their phone 5+ times. Sadly this isn't true, and this applies to every power bank on the market! To get a more accurate estimate of how many times you can charge your device, use this simple formula, with an example of using this Smart Power Bank to charge a phone with a 1,500mAh battery:   Times Charged = (Power Bank True Capacity - 35% - Efficiency Loss) / Your Battery Size.
E.g. (8,000 - 35% - 8%) / 1,500 = 4,560 / 1,500 = 3.04 Times Charged   About Us  SENMEI TECHNOLOGY CO.,LIMITED founded in 2006,which specialized in electronic products including intelligent power banks,usb flash drive,memory card and usb car charger.As an audited supplier of BV, we focus on quality control and pay attention to each opinion from our customers. With many years of experience in research, development and selling,we successfully cooperated with hundreds clients from all around the world and established long-term relationship with them.
