34pcs Plug Jack Sets

Over the years I've collected plenty of power supplies and power cables for various pieces of electronics around the house. This set of DC connectors is ideal for converting a common 5.5x2.1mm plug into something else (center contact is still the same voltage polarity) but it can also be used in determining what plug is at the end of that AC adapter, or what type of jack is on the back of a piece of gear. Just match up the plugs or try putting one of the connectors from this set into the jack. The only thing that was missing was a quick way to identify what each plug is, or in other words, the size of the barrel and the size and type of the center contact. So I took an hour to label all 34 plugs. Then I separated them into three different groups: barrel, tuning fork, and others. When going through the photos of this item I noticed some of the plugs had "tunmg fork" next to the end of the plug. That's "tuning fork"; the type of connector that's inside the barrel.

Decent set of adapters something for just about anything just know what you're getting into and remember to give you your device the correct polarity and voltage.

Works great

As advertised.

Didn't come with charger cord

Universal replacement for every little round plug

This set provides a large selection low-voltage adapters such as those used on computers, monitors, and other devices. What appears at first glance to be a USB plug actually fits the power input on some Lenovo ThinkCentre computers such as the M73 on which I am writing this review.. The input for all of the adapters is a 5.5mm x 2.1mm plug, which is available with screw terminals from several Amazon vendors. Combined with a variable power supply such as the Hyekec HY3005S, you will be able to charge, run, or troubleshoot almost any DC powered device with one of the adapters in this set.

Just what I needed if it's not in this kit you don't need it.
