Solar power isn’t something new to me, or you. I have enjoyed using my Solar lights (Luci lights), it has really changed what I pack for purposes of light. I have also used a lithium battery with a double pane solar panel with some success. The battery always worked well, but after I drained it, it could take upwards of 8 hours to completely charge it again. Needless to say, I was in the market for an upgrade.

My major considerations were; more than one charge out of the battery, fast charging if needed, and shorter recharge time. After searching around I settled on the SunJack 14W Portable Solar Charger. Over the last two weeks I have used this kit while hunting hogs in Texas, and more recently while camping with my son over Father’s day weekend. It has been a huge upgrade compared to the last kit I owned.

Unlike my old kit, the SunJack 14W Portable Solar Charger kit uses four panels with a max output of 14 watts. What does this mean? Well, in direct sunlight you can charge any USB device similar to a household outlet. Charging a smart phone using the panels directly takes about 90 mins. This kit also comes with a 8000mAh battery when direct sunlight isn’t available. This battery is good for approximately four smartphones (3 for my specific phone), or one tablet. Again, using the solar panels it takes about 5 hours to fully charge this battery.

The 8000mAh battery has a typical power indication  system. You depress a button, and then five lights will indicate how much juice is left. Hold that same button down and a built-in LED light will activate. The Battery has: DC input (5V 2A) USB Output 1 (DC 5V 2.4A), USB Output 2 (5V 2.4A or 9V 1.67A). Basically it has a fast charge, and an even faster charge. While using my phone to watch a movie I plugged into the USB Outlet 2 and I could actually watch the battery (on my phone) tick upwards. The charge was fast.
