Unfortunately, I've had a bad encounter with Energup's online store. Although their website is easy to use and they have a wide range of tools and accessories, the quality of their goods has fluctuated. I've bought several things from Energup, including a power tool and battery pack, and both of those have had problems. The battery cell failed to maintain a charge after only a few weeks, and the power drill's motor burned out after only a few uses. Additionally, I thought their customer support was subpar. It was difficult to contact a representative, and when I did, I received unhelpful and inadequate answers. Overall, I had a negative shopping experience with Energup's online business. Although they may provide a large selection of tools and accessories, it is challenging to suggest them to others due to the inconsistent quality of their goods and subpar customer service.
