SunJack 25 Watt Foldable IP67 Waterproof ETFE Monocrystalline Solar Panel Charger with USB-C and USB-A for Cell Phones, Tablets and Portable for…
Rugged, Durable and Waterproof. Weatherproof ETFE exterior layer improves performance and durability, extends the panel’s lifespan, and requires far less maintenance when compared to the PET exterior construction that is used by most portable solar chargers. The USB ports are waterproof rated IP67 – the printed circuit board (PCB) is coated with a waterproof seal and the junction box is silicone bonded to the panel. Designed for all weather conditions and environments – waterproof, shock-proof and drop-proof.
Portable and folding solar panel. Compact panels fold down to the size of a tablet and easily fit into any backpack. Integrated magnetic closure system keeps the panels closed during storage, eliminating the need for bulky straps. The pocket provides storage space for most electronics and accessories, and the mesh design intuitively allows proper airflow to prevent devices from overheating while being charged. The elastic straps secure phones, power banks and more during storage and transportation.
Powerful and fast charging speeds. Monocrystalline panels with ETFE construction provide maximum efficiency and UV-ray permeability. Dual USB ports allow you to charge both USB-A and Type-C devices. The USB-A port (5V/3A) and USB-C port (5V/3A) each pump out up to 3 amps of power per USB port (25W total maximum output) to provide wall-outlet charging speeds. ETFE construction has a UV permeability of 95% compared to 80% from PET – makes the panel more efficient than other solar chargers.
Smart Technology. Built-in smart IC chip intelligently identifies your device and provides the quickest, yet safest, charging speed. Short circuit, over-load, over-heat, over-charge, over-voltage, over-current and current limiting protection. Automatic restore if shade occurs.
Multi-Use: Ideal for camping, backpacking, hiking, outdoor adventures and is essential in any disaster, emergency, and hurricane prep kit for survival. Never be caught without power. Great for any USB device including your iPhone, Samsung, Pixel, iPad, phones, powerbanks, tablets and more.
Designed in California, backed by a 12-month hassle free warranty from a local USA company with easy-to-reach customer service. If you have any questions or experience any issues, we are here to help.

Six weeks in Africa with no electricity. Camera, personal fans, headlamps, flashlights, and the rest of the team without a source of electricity either. So we jumped on the SunJack with an Anker Astro E7 26,800 mAh, Cannon USB battery charger, and a SunJack USB battery charger. I wasn’t sure about the ability to charge all the devices, but I figured it couldn’t be worse than having nothing at all. Before leaving for Africa, we spent two weeks “prepping” in Florida, and the SunJack charger immediately proved its ability. Even though there was no direct sunlight, the solar charger kept the Anker fully charged and all the batteries for the team full and ready for the evening. While in Africa, the setup was worth its weight in gold. For the dollar, I couldn’t imagine a better solar panel. While it did add a bit of weight to my overall pack, it was worth having that fan on me at night, the ability to capture memories with my camera, and illumination at night while avoiding snakes. The ability to charge all the “AA” and “AAA” batteries, cameras, and other miscellaneous electrical devices is a life saver.
*Update* Almost a year later, and I am still in love with this solar charger. I have taken a few more international trips and have taken this with me. It has proven itself to be a great security blanket in our electronically controlled lives. This charger is a year older, a bit dirty, but still works harder than some of the folks I travel with!

Kept our 4 phones charged for a week of off grid camping. I charged powerpacks when we were not charging phones.

Just received the 25 Watt SunJack, have a warm sunny day through the front door glass at 65 degrees F outdoors, charging a Pixel 6 at “Fast Charge” equating to 10% battery life added in 15 minutes. Will try to update as I put more of a load on it but it’s absolutely worth the money. The construction is solid, rigid and durable. Built faith in the solar industry here compared to other gimmicky devices I’ve had in the past. Excellent product!

Just had a Typhoon on Guam and still don’t have power! This is a lifesaver. Charges my devices fast!

I bought this charger for a backpacking trip I went on recently. It does charge very good in direct sunlight. My daughters went with me on the trip and we charged their phones too. One was at single digits in percent charged. This charger brought it up to about 60 percent in 2 to 3 hours in direct sunlight. It’s not too big to carry and looks kind of cool with the yellow color. I’m very happy with it.

I live in Singapore. This solar charger performs well from 8am to 6pm. The photo shows a reading I’d typically get when it’s sunny, 4.95V and 1.97A. When it’s cloudy, I’d get about 0.5A.
This 25W solar charger has 2 USB A outputs. When 2 USB devices are connected to both ports, the highest total current I could get was 2.7A (~13W).
It’d be best to use a good usb charging cable. Also, the shorter the cable, the higher the current.
The built quality is great and it feels tough. There’s a magnet that keeps the panels folded together for easy packing.
The solar panel became faulty after a few months’ daily use. 1 of 3 panels stopped working, reducing the total output. I’ve returned the panel.

The USB-C cable included seems non-standard or proprietary, it won’t charge my devices if I try any other cable. The included cable also only works when plugged into this panel, it won’t work if I plug it into a wall charger. Really weird. Also keep in mind the USB-C is 5V only, max 3A (15W), which is clearly stated in the description to be fair, but certain fast charging devices may only fast charge if they are able to negotiate a higher voltage.
Being able to use my own cable is very important because I want to use the ones with the built-in LED watt display. The included cable did at least work with a Plugable USB-C power meter in line, but that’s really clunky.
Still giving it 3 stars because it did at least work to charge my phone, and the small foldable design is otherwise nice. It’s just not as great as I’d hoped, so I’ll be returning it.

USB sun power at its best. Peppers delight. Very portable. I use it to charge up my Cells, lights batteries, and my ham radio equipment. If the power goes down you will need this. Highly recommended.
