Just plug into a 110 outlet to charge it up to 100% then you are ready to rock and roll. I've included a video that shows the size with a ruler beside the power bank, I turn it on 12 volt for USB outlets then turn it on AC to power an LED desk lamp. I also used the USB to power up a stereo with a builtin lamp. With this portable battery, you can recharge your cell phones, tablets, laptops. You can power a digital LED or LCD TV if it's under 200 watts (most 32 inches and under are 50 watts or less).
If you have a power outage in your home or RV, you can use this power bank as needed.
Lithium batteries are the best to have because they don't suffer memory problems. In other words, you can recharge them after only using 10% of the battery or recharge after using 80%, it doesn't matter. The battery will top up. Once the battery is fully charged, remember to unplug from the outlet.
This unit will accept a solar charge, though I didn't have a solar panel to test it with, but I love that concept for camping, living off the grid, tiny home lifestyles and just the sheer portability.
I live in a tiny motorhome, so I am outdoors often. This battery bank enables me to have a power source where ever I want it. On the side of the unit is a built-in cooling fan that operates as needed to cool the unit down. It does get warm during use.
As with any sensitive electronic, do not use in the rain or drop it. Handle with care. The padded carrying case that holds everything you need is a very thoughtful included addition.
