Maximize charging efficiency on the go with enhanced versatility.

Universal Compatibility

Compatible with Multiple Battery Types

The DC-DC battery charger is fully compatible with a range of battery types including AGM, Flooded, Gel, and Lithium, resulting in optimal performance for all batteries.

Seamless Charging, Ultimate Safety

This charger utilizes advanced safety technology to ensure error-free and secure charging for your house battery.

Protect Your Starter Battery

The Renogy 12V 20A DC-DC Battery Charger is compatible with both traditional and smart alternators. Equipped with a D+ Ignition cable, it detects generator starts and prevents over-discharging of the starting battery, ensuring the safety of your generator. (For optimal performance, consider using an 18-16AWG copper cable. D+ Ignition Cable sold separately.)

Smart Charging Protection

The included LC cable allows for automatic adjustment of charging current, providing protection for the house battery against potential damage from overcharging. (Recommended: 18-16AWG copper cable. LC cable not included.)

Smart 3-Stage Charging

Expertly charge your house batteries from the starter battery with three stages - Bulk, Boost, and Float - to achieve automatic and optimal charging up to 100%.

Prolong Battery Lifespan

This product automatically adjusts charging modes based on battery voltages. Its temperature sensor provides -3mV/°C/2V compensation, guaranteeing the most efficient charging even in changing temperatures. Please note that the lithium battery must have a built-in BMS for optimal functionality; an external temperature sensor is not required.

good socks
Number of Items: 6, Color: Red Assorted (6-pairs), Size: Large
I like that they stay on pretty well. also liked the thickness - not too thin / not to thick. also i like that on the inside there are no random threads all over ... i found that to be a problem in similarly priced products from other major brands (and also the cheap options at costco also had that same issue). I've had them a few months and I think they'll last. *** 1 year Update *** Still great! I think they'll easily last me 2-3 yrs! Love how comfy they are. easy to pull on / off. nice colors. highly recommend. I bought some road runner sports socks for almost 5X the price at the same time i got these and while the road runner socks are pretty good for sports (they fit tighter so tend to stay on in active mode), i find these under armour socks much more comfy for daily wear.

Good coverage and size, looks nice and easy to use.
Color: Black, Size: 6 Panel
My son uses this to partially cover his window as he is in a high rise and people can look in. It is tall enough and wide enough to provide reasonable coverage and because it doesn't require putting it together, it is very handy to use immediately. Good value for the dollar and looks nice.
