- The Sunjack Portable Charger will work in the shade, although it will take longer to charge devices. For best results point the solar panels directly into the sunlight, and preferably unobstructed by windows.
- While you can charge and power devices directly from the solar panels from my experiences it is best to use the solar panel to charge the power bank over the course of the day and then use the power bank to charge and power your devices. Another strategy is since the Solar panel has two outputs you can charge or power two devices at once.
- The 4 solar panels can fold up to something that is slightly smaller (and lighter) than a typical hardcover book.
- Comes with a 8000mah power bank. At 8000mAh you can charge an iPhone 3 times or supply about a 75% charge to an iPhone 4. The power bank had two outputs - Output 1 supplies 1A at 5V, Output 2 supplies 2A at 5V.
- The overall build quality is very solid - the stitching an build quality is very solid.
Final Verdict - The Sunjack Portable solar charge is a lightweight and compact solar cell, that when used in full sunlight, can deliver up to 14 watts of power. Now of course that isn't enough to fire up a portable air conditioner or refrigerator, but it is enough to power up a cell phone or power bank. The Overall construction and build quality is very solid - so this is a pretty easy 5 star recommendation.
Please Note I received this device in exchange for an unbiased review.
I did a bit of research about the efficiency of solar cells. The SunJack’s efficiency is rated at 19%. This means that in combination with latitude and the climate, it can convert 19% of the sunlight energy it captures into electrical energy. It seems that there aren’t many solar cells out there that can do much more with a few exceptions, especially at this price point.
The SunJack comes with a 8000mah batter/power bank that has enough power to charge an iPhone 6 Plus about 2.7 times. I kept my Kindle Fire 8 HD tablet plugged to it and turned on for 2 days and I only ran the batter down halfway. Then I hooked the battery up to a Bluetooth speaker and a Kindle Fire 7 and while using those items like a radio. By morning I finally ran the battery down to the point where it was there was only 1 blue indicator light blinking (to indicate the battery was low). The battery / power bank detaches from the SunJack via a USB cord – which is nice that it’s not tethered. It might be worthwhile to purchase a 2nd battery to charge with the 1st one is being used. It took me about 7 hours to fully charge the battery/power bank. When it’s fully charged, the 5 blue indicator lights are solid, when you push the power button. The battery is a terrific feature that you can power up using the sun initially, and then use it to charge items when the sun isn’t shining! You can also plug the battery straight into a USB charger via a wall outlet for convenience sake. The SunJack has a built in voltage regulator so that you can’t overcharge the battery pack.
When the sun IS shining, the SunJack works pretty well as an instant charger – just like plugging your gadget(s) into a wall socket! I hooked my tablet directly up to the SunJack via a USB cord. I kept it running AND charging at the same time. The SunJack was able to charge it 10% in about 40 minutes. That’s not bad considering that the tablet was ON and the SunJack wasn’t in constant direct sunlight the entire time. It was also the late afternoon heading into the evening. It puts out 5 volts, so it should be able to charge any USB item that has that requirement. I read in the questions and answers that the SunJack can’t charge a laptop (via an official answer by the seller). It worked great for my tablet, though! The official description says it can charge a phone in 90 minutes, and I think that is a pretty correct assessment, as long as you put it in full sun.
As for construction – the SunJack is really well put together. When it’s all folded up, it only takes up about 9 x 7 inches and weighs about 2 pounds. It features a zipper net style pouch where the battery is stored via slipping into a stretchy strap. There are also 2 USB ports and an included plug to plug in either the battery for charging purposes, or an electronic device, if you want to run it directly off the SunJack. One of the USB ports is high power, the other low power. You can plug two items in at one time. The solar panels are covered by a water-resistant material (probably a polyester??). It stays closed and folded up via a Velcro. When you unfold it, it’s 30.75 inches long by 9.25 inches wide (AND 1.75” thick). The solar panels are mono-crystalline and protected by plastic panels. All of the stitching of the case is sturdy and well done. There are 2 carabiners that you can attach to various loops located in different places, so you can hang the SunJack on the back of your pack, a tree, or other object. I used it lying flat on the grass and angled toward the sun on a chair.
I’m really impressed with the SunJack and know it will be the first solar charger we pull out when the power goes out, or when we are backpacking out in a forest far from civilization. ;-) It puts out enough juice to keep our important items running, and I love the freedom of using just the sun to power things up. If you are looking for something for your bugout box, homestead, camping trip, emergency kit, or hike – the SunJack is pricey, but it actually gets the job done when it comes to charging things up.
I received the SunJack in exchange for my honest review. This in no way influenced my opinion, as all of my reviews are totally (and sometimes brutally, lol) honest. I don't always give out good ratings, nor do I change my ratings when asked to by a seller!! I buy most of my stuff online, so I really LOVE online reviews and try to make my own reviews as useful as possible and make sure to write details into my review(s) that I would want to read, if I were trying to make a purchase decision. Please leave a comment if you have any questions, and I'll try to answer asap! :-)
