Highly recommend this product. Test result are as follows. This unit was able to charge my android cell phone direct connect ( from cell phone to solar charger) with no problem. Fully charged in about an hour. I then charged the solar battery via solar charger, battery was charged in about 5 hours. I then plugged the battery to my android cell phone (cell phone was in the red zone and pretty much empty of power). To my surprise the solar battery charged the cell phone in about an hour. The solar battery showed 3 lights remaining. I then plugged the solar battery into my Midland ER 200 emergency radio to recharge the empty battery. The Midland radio showed 2 bars at completion. My Android phones battery is 2070 mah. The Midland ER 200 has a battery size of 2000 mah 3.7 volts. I was very impressed with the performance of this 2 panel 7 watt unit. The Sunjack was able to give me a full charge for my cell phone and almost full charge on my emergency radio, all with only a 4000 mah battery. If you live anywhere in hurricane county, earthquake zones, tornado alley any disaster areas, this is a good unit to have. Light weight, but a little power house. I'm glad I found this product, I was so impressed I purchased the 14 watt unit which I will evaluate later. I do plan on purchasing several others for my children who live in hurricane alley. I did not receive any discount for this unit. It was purchased because I live near the coast.Update: July 2018, I recently purchased the 5 watt Sunjack solar charger with 10000 mah battery pack. The instructions indicate you can full charge in 8 to 9 hours. Testing was conducted by US Special Forces individual in a desert region. After fulling depeting the battery pack attempts to charge the battery pack was unsuccessful in field conditions with extreme sun light. I tested the unit to find it takes about 5 to 6 hours of sunlight to reach 1 bar light. After 10 to 11 hours I was able to get 2 light bars indicating half full.These small units may require 20 or more hours of direct sun light to fully charge the unit. Not a deal breaker, but instructions are alittle misleading...Still a great unit... ### ⭐⭐⭐⭐⭐ Lasted one season - then out!! *by J***O on June 23, 2016* Worked well for first season 2015 but when I pulled it out in April 2016 it didn't charge battery. Battery could be charged with conventional USB wall charger but solar panels are not working.Update: After contacting Sunjack about product they sent me a new one which works well. This was handled very professionally and the way every company should stand behind their product. I was further assured that any future issues would be similarly resolved. I will certainly continue to do business with them going forward! ### ⭐ Damages the electronics *by D***I on October 7, 2018* I don't recommend this product at all. I used this product for my backpacking trip. It was supposed to charge the built in battery with direct sun. After connecting my iphone and even testing with apple watch, I figured out that the connection gets on and off which causes harm to the electronics. The panel was under the sun for the whole day but the battery apparently was not charging at all. I only used it once but the product was really defective. In addition, it is a heavy device. You might not use it for a hiking or backpacking trip. I returned the product and bought ECEEN instead. I used ECEEN in my backpacking trip for 7 days. I connected the ECEEN to a power bank and it charged the power bank. Afterwards, I connected my devices to the power bank. The good thing about ECEEN is that it has a voltage regulator which prevents damages to the devices when there are changes in intensity of sun light. The only drawback to ECEEEN is that it has a single USB output and it doesn't have a built in battery. You can't charge multiple devices with it. My solution was using the power bank. I used ECEEN every day charging my power bank and it worked without any problem. --- ## Why Shop on Desertcart? - 🛒 **Trusted by 1.3+ Million Shoppers** — Serving international shoppers since 2016 - 🌍 **Shop Globally** — Access 737+ million products across 21 categories - 💰 **No Hidden Fees** — All customs, duties, and taxes included in the price - 🔄 **15-Day Free Returns** — Hassle-free returns (30 days for PRO members) - 🔒 **Secure Payments** — Trusted payment options with buyer protection - ⭐ **TrustPilot Rated 4.5/5** — Based on 8,000+ happy customer reviews **Shop now:** [https://www.desertcart.vn/products/13919974-sunjack-5w-solar-power-bank-external-portable-battery-charger-flashlight](https://www.desertcart.vn/products/13919974-sunjack-5w-solar-power-bank-external-portable-battery-charger-flashlight) --- *Product available on Desertcart Vietnam* *Store origin: VN* *Last updated: 2026-05-24*
