Power Conversion Rate:

Technically, battery capacity of power bank does not equal to chargeable capacity to other devices. Take a 6000mah power bank for example. The capacity of power bank refers to the lithium battery inside it. When the power transfers from power bank to the mobile, it is not a 100% conversion rate due to the following reasons:

1)    Voltage transform from 3.7V to 5V: power bank lithium battery is 3.7V around, while it charges for mobile phone, 5V voltage is required. According to energy conservation principle, the battery reaches mobile phone should be 6000mah*3.7V/5.0V=4440mah.

 2)    Other factors that cause further power consumption: internal resistance of power bank &mobile phone, heating from power bank & mobile phone, etc. All these will take away some percentage of energy. For a good quality grade A power bank, the extra consumption will be about 15%. So the final power reaches mobile is around 3774mah. The formula is 6000mah*3.7V/5V *(100%-15%)=3774mah.

 Then how many times it can charge the mobile phones? See below illustration.

 Production Flow:

1)   SMT machine producing the PCBA Board, which is the core of a power bank

2)   Battery Test: to test the Voltage & Resistance to ensure they are in a safe range.

3)   Spot Welding: to weld the battery to two cables (stands for the positive&negative end).

4)   Aging test of semi-finished product:full charge, full discharge, and charge the battery again to a certain percentage of power, like 50-70%. Could not be too full.

5)   Final assembly/polishing/packing:

6)   Packed ready for delivery

All our raw materials/semi finished product/finished product are under strict check and test to ensure 100% good rate before delivery.

FAQ

Q1: What’s the difference between an adapter and a charger

A1: Basically, chargers and adapters do very similar things, but there is a difference. For example, laptops require chargers, as they usually require more power than USB adapters can provide.

Q2:What if I have a technical issue

A2: Any issues can be handled by contacting our customer support via the email provided or in our contact box on this page.

Q3: What warranty comes with the unit?

A3: All products come with a 12 months replacement warranty. In the unlikely event your unit fails within the first 12 months, return to us and we will replace providing authorized returns policies are met.

Q4: Can I print my brand logo on the chargers?

A4: Sure, OEM is available. Lazer printing and silk printing can be offered

Q5:What's your minimum order quantity?

A5: Our MOQ is 100 pcs per model. Welcome to test sample first.
