Also, you can get a wide variety of adapters that convert a 5.5x2.1mm plug to other sizes of plugs (and even other kinds of plugs, like USB), so for short-term use I use a variable power supply with a 5.5x2.1mm plug and converters to power anything I need while I wait for a dedicated power supply with the right tip to show up.

2013年3月3日 · Differentiating between 2.5 and 2.1 mm plugs is very simple. Strip the insulation off of a #12 solid wire- used commonly to wire houses. It is 2.05 mm diameter and will be loose in a 2.5 mm plug. It will just fit in a 2.1 mm plug and can only be slightly wiggled.

2022年11月6日 · The best answer is "maybe", because the plug in the picture you provided (connected to the AC adapter), looks to be of the kind that would not work with a 5.5x2.1mm jack, but many such power supplies come with plugs that work with both 5.5x2.5mm and …

2021年12月27日 · The 5.5 mm or 5.7 mm is the outside diameter of the plug, or of the plug that the socket is intended to accept. A 5.5 mm plug will fit easily in a 5.7 mm socket, but will be a bit loose. It will probably make contact with the socket, but the right size plug would be preferable.

2017年11月22日 · In the 5.5 mm O.D. connectors, if you use the 2.5 mm I.D. plug in the 2.1 mm jack it will not make good contact because the outer housing of the jack may not allow the plug to be displaced far enough for the center to make contact, and in any case the spring will not be exerting the proper amount of pressure since the plug has less thickness.

2021年1月28日 · The power bank output and the device both require 5.5 x 2.1mm male plugs. I've actually got some random cables and have found two of these exact cables. Now for the weird thing, when I test for continuity with a multimeter, it is different for these cables - so for one cable, I get continuity when I use the two outside surfaces of both the 5 ...

2015年12月31日 · With two TECs, that is potentially up to 8.2A of total current. Even with the lower power TECs, that is still 6.8A of total current. I am beginning to wonder if I can send that much power through a standard 5.5mmx2.1mm power jack. I am also beginning to wonder if I can find a DC power switch that could handle over 8A.

2018年3月15日 · 5.5mm is a standard OD, 2.1mm is a standard pin diameter. Not all connector manufacturers use the same contact system, so even though the inner contact does not look the same, as long as it is a 5.5mm x 2.1mm connector, it should be compatible.

2021年12月26日 · I found a part that is almost what I want. It says it supports 12V and up to 5A, and I need 24V and 2~3A. And another thing is that it is 5,7x2,1 female instead of 5,5x2,1. Do you reckon it would work and fit: conrad.de/de/p/…. Thanks \$\endgroup\$ –
