This is a well made cable. For 1m though £12 is very expensive. It does the job well enough but i'm not likely to buy another when i could potentially make multiple cables myself for a similar price.

This is the second of two different models of adapter cable from YACSEJAO I'm reviewing today; this one being a DC 5.5x2.5mm barrel jack to two 4mm banana plugs.The cable comes in a very similar (but not identical) resealable plastic bag to the other YACSEJAO cable.Since there have been some reviews claiming 'bad' or 'loose' contact on the banana plugs, I'll state the actual dimensions here for reference. The solid shaft is 3.75mm in diameter, while the sprung 'bulb' that makes contact with the socket is 4.7mm in diameter. The contact length is 13.60mm. For a 4mm socket this should be perfect.These dimensions are consistent with the 4mm banana plugs I have on my other cables and these plugs fit well on my bench supply; no issues whatsoever.As with the other YACSEJAO cable, the banana plugs are moulded extremely well and have great strain relief.The same is true of the DC plug. It does appear to have a 2.5mm inner diameter as claimed (although very difficult to measure accurately). It fits the devices I'd planned to use it with. The outer diameter is 5.4mm and the length is 10.45mm. It does seem to be a very high quality connector.The cable is marked as 14AWG and rated to 300V.Again, continuity and fit is fine with this cable, so I have no reason to mark it down.

Faux contacts, inutilisable

Banana plugs appear to be somewhat loose, don't fit as snuggly as some others I have, as if they're a little too short. Was the only supplier with the right size DC jack for my ts101 soldering iron.
