2/4/6Pairs Car Battery Tongs Cable Alligator Electrical Measured Clip Clamp Tool - 4pcs (2black+2red)

Every workbench eventually runs out of clips. One is on the multimeter, two are holding a test light, another pair has been jury-rigged onto a bench supply and never came back. This set of four insulated alligator clips, two red and two black, restocks the drawer.

Copper-plated jaws, PVC boots

The clip bodies are an iron-nickel alloy with copper plating, which keeps contact resistance low enough that a reading is a reading rather than an artefact of the clip itself. Each one is roughly 80 mm long and sleeved in a PVC boot, so the metal is covered where fingers go and two clips can sit close together on a terminal block without shorting across. Colour coding is the dull detail that saves you: red on positive, black on negative, no thinking required at 11pm.

Rated at 250 V / 50 A, and what that rules out

The supplier rates these clips at 250 V and 50 A. That covers multimeter work, test lights, bench supplies, small chargers, solar panel testing and electric fence work - all applications the supplier names. It does not cover jump starting. Cranking an engine draws current far beyond 50 A, and a clip this size in that circuit will get hot enough to be a real fire risk. Use proper jump leads for that job.

Key features

• Set of four: two red and two black, so both polarities are covered twice over.
• Iron-nickel alloy, copper plated: the supplier's stated construction, aimed at a low-resistance contact.
• PVC insulated handles: the metal stays covered where you grip the clip.
• 250 V / 50 A supplier rating: published as stated, not converted or inferred.
• Compact 80 mm body: small enough to work in a crowded fuse box or on a terminal strip.

Before you clip these on

• Not for jump starting or engine cranking. The supplier's 50 A rating sits well below the current a starter motor draws, and undersized clips in that circuit are a known fire risk.
• Jaw opening is not published. Check the photographs against the terminal, stud or busbar you intend to clip onto.
• The supplier's description offers a choice of 2, 4 or 6 pairs. Only one pack is stocked on this listing: four clips, two red and two black.

A cheap drawer item that you only ever notice on the day you haven't got one.
