Onite Male to Male Extension Cord, DC 5.5x2.1mm Power Adapter Cable, for LED Strip, Surveillance Camera, CCTV Security Camera, LED Display, IP Camera, DVR, Router, Invoice Printer, 2-Pack

When you accidentally run your security system wires through a narrow attic and realize you need to rerun them, this is a better alternative.

If your project requires this, it will work just fine!

I use them to connect my Netgear modem and router to a backup battery unit. Right size and works fine. Cannot comment about durability as I just got them.

this 5.5 x 2.1mm cable fits the Omnicharge Omni Mobile USB & DC laptop external portable battery. i bought it to connect the battery pack to my Fujifilm GFX 50S and it works perfectly. the smaller than average gauge wire is much more flexible, making it easier to use and pack up for travel.

I put this out in direct sun and hooked my cell phone that I allowed to drain down to 5% it did charge it up to 40% in a few hours. Its here for emergency. Its not a battery and u must place it in direct sunlight to get the best results. It did work. A laptop probably longer. But in an emergency nothing is way worse. Better have amateur radio. I did not try it but it my charge my portable power bank ie Anker charger to charge my Armature 2M 440CM HT. Ill try it

Cables work just as I expected, tight connections, works well.

Great item, price and great delivery time.

Used these to make some modified power cables .... they worked fine.

Good quality cables.

It seems fine
