Quickly I unpacked the product and off I go with my Samsung Galaxy S4 charging! Am really enjoying the use of this product. I strongly recommend everyone who loves traveling like me should go for one because it will really be of help to you.

Thanks to LUMSING for this great product. Am looking forward to new 16000mAh Power Bank in the pipe line.

Did a bunch of research before purchasing this battery backup. Many reviews on other products described how the supplied charges where not as advertised. The Lumsing 10400mah Power Bank however seemed to stand out amongst others and live up to it’s credentials. With the initial charg that was shipped from Amazon I was able to Charge the following:

Simultaneously charge an iPhone 4s at 2% in 2.5 hrs and an Galaxy s4 with 10% in 3 hours. There was still 3 bars of power remaining on the Power Bank. I used the remaining power to charge an iPad 2 from 20% to 56%.

Recharging the device for the first time did take some time, roughly 10 hours.

After my first recharge i tested again with the same products.

iPhone 4s from 5% to fully charged in less than 2hrs (still 4 bars on the Power Bank)
a Galaxy s4 from 36% to fully charged in less than 2 hrs (3 bars remaining)
A completely depleted s4 to fully charge in 2 hrs (still 3 bars remaining)
iPhone 4s from 30% to fully charged in 1.5 hrs (2 bars remaining)
The reaming 2 bars charged an iPad 2 from 63% to 73%

Recharging the device the second time around took slightly less time, roughly 8.5 hrs.

Overall very pleased with the Lumsing Power Bank 10400mah, as i will be using this mostly for craft fairs where i will not have power and will need to charge my apple devices for streaming wifi and accepting credit card payments.

The cables and carrying are also very nice in quality and overall a very affordable price.

Looking forward to seeing what other products this new company has to offer.
