The CTEK 20A Off Grid Charging System charges your battery bank while you’re driving to stop it going completely flat so you can spend more time off grid. You can charge it from smart alternator, solar or wind power and, for complete peace of mind, you can see at a glance how much charge you’ve got left and the length of time till your batteries are discharged.

The D250SA charger can get its energy from smart alternators, solar panels and wind power. It separates starter and service battery and maximizes the use of the both without risking that the starter battery is unable to start the engine. The CTEK MONITOR constantly monitors the voltage and current (charge and discharge) to show you exactly how much charge you have and how many hours you’ve got left before your battery bank is empty.

Great price, not great quality
Material Type: Recycled Polyester, Color: Black, Size: Small
Simple, straight forward all black polo. I am a size medium woman (with some room since I don't like form-fitting) and bought a men's small. Fits perfectly for my frame. Long enough to tuck in for my part-time extra weekend job uniform. Also suitable for the golf course. A little thin, and if you hold it up to light you can sort of see through it. *Not* flowy, soft and smooth fabric like a rash guard/sun shirt - more structured than that. But it's cool and does the job for the price under $10.

Great purchase
Material Type: Recycled Polyester, Color: Dark Navy, Size: X-Large
Purchased several shirts, all were great quality. You never know what you’ll get when you purchase sight unseen, these are worth it. Great value, style, and comfort. Color is exactly what you see online. True to size.
