I’m really glad that after much deliberating, research and comparison I chose this company and model as the design, quality and engineering is superfluous, from unboxing, inspection to usage and features (I’m really impressed)! This is clearly a premium and thoughtfully designed and constructed product with so much attention to detail. The size is incredible due to its innovative convection cooling system and modular design. The craftsmanship, materials and feature set is also excellent as it can work with many different battery types and provides a range of really useful smart design features (like permanent installation via an included harness, auto maintenance and a repair option)! These features give you peace of mind, and make recharging safer and easier. I’m so glad I discovered NOCO as this is design excellence!
