Review: Surprisingly good quality AC/DC current clamp - I have a 87V MAX True-RMS and I really needed a current clamp, but I couldn’t afford the $300 for the brand specific clamp. Then I saw this Allsun EM264 AC/DC mini current clamp, and thought I will give it a shot. For $30 bucks, I’ve got nothing to lose. Plus, I had a cheap multimeter I could test it out on, before using it with my 87V MAX. But once I confirmed it worked, I had no concerns about using it with my 87V MAX. Well, when the clamp arrived, I was extremely surprised at the quality of it. It was not what I was expecting for $30 bucks. It’s the age-old problem of buying things online, you just don’t quite know what you’re really getting until you have it in your hands. The instructions they provide on the desertcart product page is essential for knowing how to hook it up correctly to a Multimeter, but once done correctly, it works like a charm. I was also able to check it’s readings against other, more expensive, AC/DC current clamps and was very pleased with how close the readings were. Mind you, I have only used it on a typical house circuit, running in the 10 to 14 Amp range, so I can’t attest to it’s performance for anything higher or lower than that. In short, if you want a CAT III AC/DC current clamp with a max capacity of 400A / 600V, but you are like me, and can’t justify, or can’t afford, spending $300 on a high-end, best-in-class ,current clamp, I would highly recommend considering the Allsun EM264 mini clamp. For the price, I give it 5 Stars. The only criticism I have is the two-position AC/DC selector button, and the current range, on/off, slider-switch. The two-position AC/DC selector button works fine, but the distinction between the two positions is not as robust as I would prefer, and it is a little easier to inadvertently press it during use than I would like. The current range, on/off, slider-switch is no different than any other such slider switch I’ve ever used, I just personally don’t like those kinds of slider switches. Again, like the two-position AC/DC selector button, the distinction between one position and those types of slider switches is not as robust as I would like, but it works fine just the same.
Review: Pretty good clamp - I got this because I didn't want to change blown fuses on my new multimeter. The DC accuracy is very good! I'm impressed. The AC readings did not match with my old clamp meter. My main use for this is for DC circuits and as such it is a good purchase for my purposes.

## Features

- 【PRECISION AC/DC CLAMP METER W/ HALL EFFECT TECH】 Accurately measure AC/DC currents up to 400A (600A overload) using advanced Hall Effect sensor technology. Features True RMS conversion, dual-range sensitivity (40A: 10mV/A; 400A: 1mV/A), and ±2.5% accuracy—suitable for HVAC, automotive diagnostics, and industrial circuits.

### ⭐⭐⭐⭐ Pretty good clamp
*by M***L on February 22, 2024*

### ⭐⭐⭐⭐⭐ It needs a separate multimeter that can measure DC millivolts.
*by C***N on October 26, 2025*

It works as advertised. Its price is low because it requires a separate multimeter for display. It displays current on the multimeter's DC millivolt scale. on the low scale, 40 amps displays as 400 millivolts (0.4v), 1 amp as 10 millivolts and 0.1 amp as 1 millivolt. If your multimeter can read down to 0.1 millivolt, that corresponds to 0.01 amp (10 milliamps).
