Each tip is color-coded and has a different letter stamped on it, but the brief instructions that come with this product don’t use either to identify the different tips. It’s a shame that after someone in product development went to the trouble to mark the tips so clearly that those preparing the product literature did such a shoddy and lazy job. They must suppose most people will just jam tips on until they find one that works.

The key used to select output voltage has a handy hole in the fob; I tied a string to it which I looped around the grooved strain-relief on the power cord to make sure I can find it when I need it. This is another thoughtful design touch that I appreciated.

I used a volt meter to measure output voltage at each setting and got the following readings.

Setting Measured Output Voltage (VDC)
——– ————————————-
3.0 3.31
4.5 4.76
5.0 5.40
6.0 6.43
7.5 7.84
9.0 9.44
12.0 12.54

I’ve only had the product for half an hour, but so far it works as advertised. I’ve subtracted 1 star from the rating for the feeble instruction sheet.

Top Critical Review

Effectively, it’s too long.
It’s about 3 times the length when connected as a regular stubby power connector, and the weight causes it to hang out of connectors in that slight slack space they have.

Somehow the design needs to be shortened.

It does work, but you can feel the stress it’s putting on the socket.
If it’s an older socket, I can imagine it might not work at all just for that reason without propping it up.

I notice they do sell a right angle version that goes up to 12v 3A, which is what I needed but didn’t notice when ordering this one.
While even that one looks like it has a much longer back overhang, the 90 degree turn would help alleviate that weight pulling so far back in a connector that only allows such a small part to hold it in place.

I may return and swap them over. I feel this one is disabled in it’s design.

Customer Questions & Answers

I don’t understand the polarity function. How can I tell if I am using the correct polarity?
Answer:

With all DC (direct current) powered devices, it will be either negative or positive grounded. The device should tell you which. You can tell which usually this way. If the device requires a positive voltage for the tip or center of the power supply plug, it is has positive polarity signified by a + symbol for the??

what is the max voltage ripple?
Answer: 3-12v, 3.0 Amp, 36W

will it work with scanshell 800dx
Answer: As long as it’s with in the voltage and you have the right fitting to plug into your product it should work just fine.
