The research file for this topic holds nine results, and every one is a test hook clip, a hook-to-hook lead or a multimeter lead with a hook end. None of them is a Powerprobe-branded product, so this page does not compare any Powerprobe model. It compares the nine listings by the plug size they fit, the stated voltage and current rating, and the hook or clip design. The listing data was checked on 2026-10-11, and every figure below is what the listing states.

Quick answer

If your multimeter leads use a 2 mm plug, the mini hooks from BOCEUC, PEHUAO and the 2 mm jack listing are the group to compare. If you use a 4 mm banana plug, the flexible hook clamp, the 4 mm hook kit and the Thuchopy leads are the group. For the highest stated rating, the flexible hook clamp lists CAT III 1000 V and CAT IV 600 V at 6 A, and the 4 mm hook kit lists CAT III 1000 V and CAT IV 600 V at 10 A. Check the plug size on your meter before ordering, since the listings state the connection type in different ways.

How we chose

All nine research results were kept because each one is a test hook, hook-to-hook lead or hook-ended multimeter lead. The listings are grouped by plug size: 2 mm, 4 mm and mixed. The order of the picks follows the order of the research file, not a ranking.

The comparison keeps plug size, rating and hook dimensions in separate columns. Where a listing gives no rating or no plug size, the table says not stated rather than assuming one.

Worked example: fitting a wire and a component in the jaw

The E-Z-HOOK listing states that its alligator clip fits components up to 0.31 inches. Converting that at 25.4 mm to the inch gives 7.87 mm, while the listing states 7.92 mm, so the two figures differ by 0.05 mm. The piercing needle takes wire up to 0.15 inches, which is 3.81 mm.

The 4 mm pair lists a front hook opening of 6.4 mm, which is smaller than the 7.92 mm jaw figure from the E-Z-HOOK but larger than the 5 mm maximum opening that the DORHEA cables state. A component with a 6 mm lead would therefore fit the 4 mm pair and the E-Z-HOOK but not the DORHEA hooks. These are comparisons of the stated numbers only, and the listings do not state how each hook grips a given lead.

What the listings do not say

Many listings leave out the brand or the model. The flexible hook clamp, the mini hook with a 2 mm jack, and the 4 mm pair give no brand or model. The Mezfrguo listing gives a unit count of 12 in one field and 10 in another.

Several ratings are not stated for the basic hooks. The Mezfrguo, E-Z-HOOK and DORHEA listings give no voltage or current rating. The Thuchopy listing gives 1000 V and 10 A, but gives no CAT category. None of the listings describes a calibration certificate. Confirm the rating, the plug size and the pack count on the product page before ordering.

Frequently asked questions

Which picks fit a 2 mm plug?

The BOCEUC BC5530160-1, the PEHUAO 4-piece kit and the mini hook clip with a 2 mm jack all state a 2 mm push-in connection. Check the plug on your own meter before buying.

Which listing states the highest current rating?

The mini hook clip with a 2 mm jack states 10 A at CAT III 600 V, and the 4 mm pair states 10 A at CAT III 1000 V and CAT IV 600 V. The Thuchopy leads state 10 A at 1000 V.

Why does the Mezfrguo listing show two different counts?

The unit count field reads 12, while the number of items field reads 10. Confirm the number of pieces on the product page before buying.

Are these figures independent test results?

No. The figures are the ones each listing states, and each carries the date it was checked. They are not measurements made for this page.

Conclusion

For a 2 mm meter, the BOCEUC and the 2 mm jack hook are the most fully described picks, with stated ratings and push-in connections. For a 4 mm meter, the 4 mm pair and the Thuchopy leads both state a 1000 V rating, and the 4 mm pair also lists a CAT IV 600 V rating and a 6.4 mm hook opening. The rest of the set leaves out too many figures to compare directly, so check the plug size and rating on the live page before ordering.
