I’ve got a quick review for you today of another portable USB battery pack from Lumisng called the Grand A1 Plus and it is 13400mAh in capacity so it can charge your devices several time or multiples devices at once as it has two USB ports. The battery pack is small and well made so it’s very portable to take with you. Read on to learn more…

The battery is gold in color but there are other colors available if you want. It’s about 4 x 3 inches and about .5 inches thick and it weighs about 9 ounces.

In the top right corner are four tiny LEDs that light up blue and indicate charge capacity in 25% increments.

On the top end you’ll find two regular USB ports along with the micro USB port for charging the battery itself and then a white LED which acts like a flashlight.



On the right side is a small white button that used for checking the battery capacity and turning on the flashlight. To turn on the light you just hold in the button for about 2 seconds and then do the same to turn it off.



I used the Lumsing battery with my Samsung Galaxy S6 phone and tablets and other things that needed charging and power.


I tested the charging capability with my Power Practical USB meter and with my phone it was charging at 5 watts and 1 amp and I tested with my PS Vita as well and it could charge it at the same speeds. One thing to note is that I’ve reviewed several of these batteries from various companies and not all can charge the PS Vita for whatever reason, but this one can which is a good thing in my opinion.



The Lumsing Grand A1 battery is very well made and best of all it’s small making it portable, you can just toss it in your bag and go and it won’t take up much room at all.

The battery has two USB ports so you can charge more than one device at a time and the ports are capable of 3amp output so it can charge your devices quickly if they can handle the power.

The battery has a built-in white LED as a flashlight which I like, I think all batteries should have one as they can be very handy.
