For example,

Let's say you take your laptop to the beach with a fully charged battery that is inside your laptop. T hen you use up all the battery in your laptop, you can then connect your laptop to the testbank/battery pack. (If you want, while at home you can charge your 20k testbank directly to your AC outlet). It takes about 5 hours to charge completely. (The 12k battery bank takes about 4 hours to charge with your AC connection at home.)

Since you are at the beach getting some sun, you connect the solar panel to your battery pack, so you can keep charging your battery pack. This way you can use your laptop for as many hours as you need.

You can just buy the battery pack called testbank , charge it at home and take it with you, and use it as a portable power charger.

This is good for short trips. You can charge your phone up to 8 to 15 times with a fully charged 20k tespack/battery bank.

If you go to an amusement park like DisneyLand, you can spend the whole day providing charge to your several family members portable devices.

If you go camping or hunting or fishing or mountain climbing for several days and you are away from any AC connection, then you would buy the solar panel and the back pack (Beetle or Everest) and the 20k milli amp tespack/battery bank.

If you are on business you can buy the BLADE laptop bag, insert your solar panel and connect your 20k milli amp tespack/battery bank. This way you can charge your laptop all day. You only really need day light hit your solar panel, in order to generate a charge for your tespack/battery bank.

If you are on a plane, you can use the solar panel and place it on the window in the airplane , so you can keep charging your laptop, as you travel.

You can buy each part individually or you can buy a package called Smartpack.
