I’m continuing to test and experiment with the Sunjack portable solar charger, and today I’m testing the battery charge time. The 8000mAh battery is completely empty, and I’m using the 14 watt 4-panel solar charger in direct sunlight.
The test went pretty good, the only thing was that the indicator lights threw me off a little bit. There are 5 indicator lights on the battery, each one signifying 20% charge–so when all 5 are lit up, it’s 100% charged. After several hours of charging, the battery only showed 1 indicator light on, and a 2nd one blinking (which to me looked like it was still working on the charge between 20-40%). I unplugged the battery from the charging panels however, and when I turned the battery back on, all 5 indicator lights came on, showing full charge.
This is a great little unit, and so far, I’m impressed. Would be a great prep for a bug out bag or a car kit. Perfect for charging phones, HAM radios, backcountry GPS units, tablets, cameras, satellite phones, and other small handheld devices.

boat striping eco friendly
http://www.sys-teco.com/boat-cleaning/boat-bottom-paint-removal.html
Boat striping eco friendly must be done regularly in the underwater area before a new coat. The conventional methods are grinding and sandblasting. Both methods are very stressful, time consuming and cause a lot of dirt. In addition, various protective measures must be observed in sandblasting.
The patented Tornado ACS cleaning machine works according to a unique future oriented vacuum blast method with special granules. The minimally abrasive technology allows an eco friendly cleaning, stripping and decoating of surfaces. With the vacuum blast method it is cleaned in a permanent cycle. The granules can be reused again (up to 100 times).
The cleaning equipment is easy to use and applicable for everyone. Thus, the cleaning machine Tornado ACS is the ideal alternative to grinding, sand blasting machines and dry ice blasting.
With the cleaning machine Tornado ACS boat stripping eco friendly is easily done on a trailer and without polluting the environment. The surfaces to be stripped to the hull, can be fixed well. To mask the remaining areas is not necessary.
The Tornado ACS is a worthwhile investment for any boat club and every marina. Especially for small clubs, this cleaning technology suits perfectly. Due to the closed cycle of this vacuum blasting method, all paint and dirt residues and granules remain inside of the system. Since neither high pressure, water nor chemicals are used, protective clothing and barriers are not necessary during the eco friendly boat stripping
In addition, the cleaning machine is often used in graffiti removal, facade cleaning, fire damage restoration and saltpetre and lime removal.
Systeco stands for effective and eco friendly cleaning methods. With our patented vacuum blasting method we have developed future oriented cleaning machines. The company guarantees the quality of its solid long-lasting products. On our website www.sys-teco.com you can get comprehensive information about the systeco cleaning technology and the many possibilities of the Tornado ACS cleaning machine.
