EF ECOFLOW DELTA 3 Max 2048Wh Power Station Review I was tired of extension cords running across the garage every time I needed power for my tools or during a blackout. So I tested the EF ECOFLOW Portable Power Station DELTA 3 Max, which packs a 2048Wh LiFePO4 battery and 3400W X-Boost output into a … Read more
EF ECOFLOW DELTA 3 Max Plus Power Station Review I was stuck without power during a storm last year, and my old gas generator was too loud and finicky. So I tested the EF ECOFLOW Portable Power Station DELTA 3 Max Plus, which packs a 2048Wh LiFePO4 battery and 3000W max output. This thing is … Read more
EF ECOFLOW TRAIL 300 DC Power Station Review I was tired of hauling heavy power banks on backpacking trips that barely lasted a weekend. The EF ECOFLOW TRAIL 300 DC Power Bank Station packs a 288Wh LiFePO4 battery into a shell that weighs just 2.58 kilograms. This unit is built for campers who run coolers, … Read more
I panicked the first time my UNI-T multimeter showed zero amps on a live circuit. It turns out many hobbyists face this exact issue and assume their meter is broken. Most UNI-T meters require you to physically move the red test lead to a dedicated current jack. Without that simple switch, you will never get … Read more
When you use a clamp meter like a UNI-T to measure current, you might see a reading that seems too high. This happens because the meter is designed to measure one wire at a time, and wrapping the wire multiple times changes the reading. Clamp meters actually measure the magnetic field around a conductor, not … Read more
Many of us who own UNI-T multimeters get annoyed when the backlight shuts off too quickly. You might wonder if hacking the EPROM is the answer to making it stay on longer. The short answer is that UNI-T multimeters typically use factory-programmed microcontrollers, not user-accessible EPROMs. I have learned that attempting to modify this often … Read more
When your car battery dies overnight, a parasitic drain is often the culprit. I need a multimeter I can trust to find that tiny current leak, and my UNI-T is usually the tool I grab first. A good UNI-T model, like the UT61E, can measure down to 0.01 milliamps. In my experience, that level of … Read more
You ordered a replacement UNI-T multimeter, but when it arrived, it looked like someone had already handled it. This is frustrating, and you want to know why it happened and if the meter is still safe to use. I have seen this issue with several UNI-T models, and it often comes down to quality control … Read more

I have noticed my UNI-T multimeter struggles with DC current readings. This matters because inaccurate measurements can lead to faulty troubleshooting or wasted time on electronics projects. The issue often comes from the meter’s shunt resistor design, which can heat up and change resistance during use. Many budget-friendly UNI-T models sacrifice precision in the DC … Read more
