Lumsing Grand A1 Plus 13400 mAh Power Bank

Lumsing sent me their largest and smallest power bank and I have been using it for off grid and survival lighting for a while now. This is what I think of it. Read the full review: http://www.thedoityourselfworld.com/blog/?p=1987

They say this is the smallest power bank in its capacity range on the market. I can tell you that I have not seen anything smaller with this large of a capacity.

For comparison I have two emergency jump starters with Li-ion battery packs inside them and these have the same capacity as the Lumsing Grand A1 power pack but they are much larger.

This little power pack holds a lot of energy and last a very long time when you are off the grid or out in the woods camping.

I have used this power pack hiking, packing and on survival trips. I took it on our honeymoon to use as a backup and as power for our night lighting.

I use it as the main power supply for my LED lighting in the off grid tiny house office.

The Lumsing Grand A1 power bank has two USB outputs so you can charge two devices at one time. I have done this on several occasions. Well, actually I have charge up my cell phone while running an LED light.

I recharge the Lumsing power pack using a portable solar panel most of the time. This gives me free energy which is separate from the tiny house off grid power bank.

With its large capacity this power bank keeps my USB LED light going for days before I have to take it back to the solar panel for a recharge.
