Solar Backpacks Reviews – Back To School

The Back To School rush has started again. In looking around the internet, I noticed that now some solar backpacks are being offered. Basically, these backpacks have a flexible solar panel on the outside of the backpack which charges a battery. This battery/solar panel can then recharge portable devices.
Big Disclaimer here – These are SMALL solar panels and battery packs on these solar panel backpacks. You won’t be able to recharge your laptop. These are designed to recharge your iPod, iPhone, mp3 player, cell phone, or other small portable electronics. You’ll typically plug your device into the USB port on the battery pack to recharge. Read on for reviews of the solar backpacks we looked at.

Blue Solar Backpack and Cell Phone Charger

This solar backpack and cell phone charger is rated for 3W which means that with full sun, these solar panels are pumping about 1/2A which about what a typical USB port gives. Any excess power is stored in the battery pack which can hold 3000mA. Adapters are included

  • Pros: Large capacity battery. Decent power output can charge devices directly.
  • Cons: Requires an adapter. The power output is 6V but USB is 5V. Using a USB plug would allow people to use their own USB to device cable.

Samsonite Solar Backpack

This is advertised as a business solar backpack. This solar backpack and cell phone charger is rated for 4.5W. This one has a 12V adapter which would be nice for powering those adapters making use of the car charger. Even at 4.5W, the current output is less than 1/2A. Most of the energy is probably lost to heat in the conversion process. This one doesn’t seem to have a battery.

  • Pros: Has a 12V adapter so you can use your existing car charger.
  • Cons: No energy storage in a battery. Rather low current.

Other Solar Charging Options

Another option is to buy the solar charger separately and just keep it in your backpack. I like this idea the best because in most cases, the excess energy can be stored in a battery or the battery can be charged from a USB port so you’ll have it when you need it most.

ReVive Solar Battery Pack

This battery pack can be re-charged from the sun or through a USB port. Once the battery pack is charged, use it to charge your other portable devices – without being in the sun. I like the fact that you can use your existing USB cable instead of having to carry around a bunch of special adapters for that solar panel charger. Unfortunately, the solar panel will only charge the battery to about 50% of capacity. On the plus side, it includes an LED flashlight and LED power indicator. This is my favorite of the bunch.

  • Pros: Has a USB adapter so you can use your existing USB charging cables. Energy storage in battery. About 1/4 the cost of a solar backpack.
  • Cons: Only charges battery to 50% with solar.
