6V 2A Wall Power Adapter for Scanner / Surveillance Camera + More (US Plug / 5.5 x 2.1mm)
Exact replacement for my HG1700 2wire power supply
posted by xfer62
Not very big, it's light and feels solid.I bought it to replace the broken power supply of my 1700HG 2wire modem because is 6V 2A. I thought I was going to cut the plug in the end and swap it, however, the plug is exactly the same.
I was wondering if + and - were inverted vs the original power supply, I didn't have the old one to compare, I took the risk and works!
I recommend it because it works and has an acceptable quality for a good price, best thing from dx.com is that I received it in my door.
Replacement 12V 1.5A US Plug Power Supply Adapter for Router + More ( 5.5 x 2.1mm / 1.5M)
Decent, no issues yet
posted by ed2096
Good small decent adapterClose to 12V (measured around 12.7V)Closer to 12V under load (1.5A)Separate AC cord, a bonus if you want to strip it down and direct wire
Used it to (under) drive LED strip (max 2A)Average heat, haven't used it constantly for more than an hourDidn't use the plug, no comment, stripped the wires, they were stranded (gives it flexibiliy), would have like to see solid core, but would have been less flexible
Cheap, seems reliable, separate AC cord makes this an easy buy for me
5.5 x 2.1mm DC Power Plug Alligator Clip Test Lead Cable - Red + Black
Good priced product for prototyping.
posted by Yodrukknop
Very easy-to-use product when you are 'prototyping' electrical circuits with DC Power plugs.I used it in combination with 2.1 Diameter DC Jacks. the alligator clips works perfect. they have a perfectly sized clips.
Good price for product, i bought 4 at a time using it for 'pre assemble' circuits before i have to solder anything.
product with good price-quality ratio
DOS-5-1 AC Power Charger Adapter - Black (AC 100~240V / DC 5V 1A / EU Plug / 5.5 x 2.1mm)
Stable power source for DIY projects
posted by isty
Stable output, good construction, very low heating.
I am using it for driving 25 addressable leds where the output of the source need to be quite stable and it works like a charm. The overall heating is very good ( the LEDs are running for several hours and the source is nearly heating at all ). The output is sometimes +/- max 0.4V, but that is a normal behaviour for sources
For such a really great price I truly recommend this power source
Power Supply AC Adapter for Surveillance Cameras / GPS / Router + More (5.5 x 2.1mm Plug)
This was the best compared to the other similar ones
posted by garytomato
I've bought three different adapters on Deal Extreme and I must say this is the only one that I'm satisfied with.The round plug at the end is big enough so I can use it with my old Western Digital external hard drive. The other two had smaller plugs which I couldn't push into the drive.
I wanted an adapter that has the electric plug built in but this was the only one that had the round plug big enough for my drive. I'm not sure how the good inner quality is but this is the only one that worked for me.
Buy it if you need something like this.
