CENTROPOWER DC Power Cable 12V 5A Plugs Male Female Connectors for CCTV Security Camera Pigtail Power Adapter Connectors (5.5mm x 2.1mm, 10 Pairs)

This was the right connector for our battery pack for the Raspberry Pi Robot kit

Exactly what I had hoped. Great worksmanship.

So far, so good

Works like is should

These work great in my portable battery box and for pig tail connectors. Nice tight fit for a strong connection.

Order was delivered in good time and item was as described.

Snug fit, well made

It seems like 5.5x2.1mm is the more common standard in a lot of the network, electronic, lighting, and hobby stuff that i use, so i did not hesitate to get this 10 pair of m/f set. I installed 3 of them in the first week and plan to keep them on hand. I had no fit issues with anything i installed. Soldering and crimping are easy and i believe these will be durable and up to the task for my needs.

Good quality. Got tired of the wires falling out of the connector or the barrel of the connectors falling apart on another set I had.

Ive been using Anderson power poles for a great variety of power uses, but had a few gotta wiggle it issues which made them fairly unreliable in my opinion. I switched to these in place of the power poles and never looked back. They are quick, reliable and easy to install. Just use a dependable crimper and I also use heat shrink tubing to jacket the crimps and I have a workable, long lasting alternative to power poles.
