It arrived in perfect condition despite the extensive shipping process on a US Navy ship. I appreciate the individual charging channels for each battery, and the status display on the LCD screen is a great touch. Just keep in mind that a USB device can't charge simultaneously, but that’s not a problem for me. Overall, I’m thrilled with this product and confident it will save me money in the long run!”

“After trying out the Tenergy Super Universal Battery Charger, I’ve found it to be incredibly easy to use and effective. My only slight complaint is that it’s too small for my liking—I wish I could charge more batteries at once. The discharge feature is fantastic, allowing my batteries to go through a complete cycle. It’s a well-thought-out product that delivers on its promises every time. I highly recommend it for its value and performance.”

“I recently bought the Tenergy T9688 charger and I’m very pleased. It holds all the officially supported battery sizes securely, and I love that it can even handle quad-A batteries. The charge time is moderate, which I appreciate because it helps the batteries last longer. I also find the USB port useful for small tasks, even if it only provides low power. Overall, the Tenergy chargers feel solid and high-quality, and I plan to buy another one soon to replace my old chargers.”

I've got a collection of rechargeable batteries that have lost their reliability over the years, but the Tenergy charger has helped me fine-tune each battery according to its size and charge level. With a full cycle of discharge, recharge, and test, I've even managed to refresh some batteries I thought were done for."

"As an electrical engineer, I bought these 9V batteries to keep my multimeters running during long tests. They perform well after several cycles, and I even bought a set for my home. Just keep in mind, they do self-discharge faster than traditional batteries and take around 9 to 10 hours to charge fully when dead."

"My mom has been using a TENS unit for 20 years, and we were struggling with batteries that only lasted 4-6 hours. The Tenergy solution is fantastic—it charges quickly, won't overcharge, and has a charge indicator, all while utilizing just one outlet. This has saved us both time and outlet space!"

"I am very pleased with this charger and the batteries. Everything works perfectly after 3-4 months of use. The batteries charge really fast, and I'm always surprised when they're fully charged.
