TekPower TP12001X 120V DC Variable Switching Power Supply Output 0-120V @1A, Digital Display with Back Light

Like most, I bought this for anodizing titanium. I am an Electrical Engineer by trade so I have had A LOT of experience with benchtop power supplies. Is this this the nicest one I have used? Absolutely not! Then again its a 120VDC power supply for ~$150. BK Precision would probably run close to a grand for the same voltage/current power supply. All I was expecting was a Power Supply that could provide 1 amp of power at 100VDC, and I got it. I didn't even need the voltage output on the screen to be accurate as I planned to simply hook my DMM in parallel to read the voltage output instead of the screen. However, when it came in I was pleasantly surprised. I hooked my DMM directly to it and read the output from 0VDC-120VDC and the display is right on within 0.1V. Now this is under a no load condition, but oh well I am not spending a bunch of time to read the output under various loads.The only gripe I have with it is the leads that come with it are not the best. I personally wouldn't use them to carry an amp of current, but they'll work I am sure. I ALMOST gave it 4 stars for this reason but then remembered we are talking about a $150 power supply here that would still be worth that even if it came with no leads at all. I simply used a better set of leads I have laying around and it works great for its intended purpose.I have not measured voltage ripple or anything to confirm, but again, it works fine for its intended purpose I bought it for (anodizing), so I don't really plan on measuring the ripple with an O-Scope either.All in all, its a great power supply for the price. The leads leave something to be desired, so if you want a more robust set, buy some for $10.

I have another version of this (different company, more expensive) that works exactly the same. I can set the voltage on both machines and get the same results. I highly recommend

Been using this power supply unit for years and it’s still going strong. Easy to use, quite and best value for the money. I’m happy with my purchase and have no regrets with this purchase.

Barely lasted 2 weeks and 4 to 5 uses before the unit failed and output dangerously high over voltage. I guess I should be glad it didn't just burst into flames. The unit clicks and pops from the voltage regulator which is normal for these units but on the last use I had the voltage set to 60v and performed a check. Then the unit on its own with nothing connected jumped from 60v to 198v! The unit would not lower the voltage at this point and the lights in the room began to dim. I powered it off and unplugged it immediately. To double check before returning the unit I plugged it back up and powered it on, it immediately jumped to 198v again and would not adjust. The unit will jump from 196v to 199v and nothing else. It is now being returned and I am hesitant to buy another since these are all the same units from Amazon or multiple other companies online. You can tell by the case design they are all the same units just re-badged for many different companies.

Got this to learn titanium anodizing. Does the job

This power supply is ideal for anodizing titanium jewelry. Try different voltages and get bright patina colors on titanium: blues, pinks, greens, golds, etc. You will need borax for making an anodizing bath, but there are tables available online which give the voltage settings for the desired patina colors. When used correctly, this power supply will yield rich colors beyond basic gold.

I am new to Anodizing Titanium so I cannot offer too many details about the machine itself except to say that it functions flawlessly for me so far after having anodized several items. I purchased this mainly for working on knives and it would be hard to beat for the price. It should be noted that this exact machine is sold under multiple different brand names on different websites, some at nearly double the price it is offered here... It is simple and straight forward to use and I have had no trouble with the alligator clips or wires that came with it... Very good tool.

Probably one of the coolest experiments you can do is anodizing titanium. It's like dyeing easter eggs for adults, only dangerous. This machine does beautiful at it. Much more satisfying than using daisy chained 9V batteries, and you can get gradients if you have a friend there to adjust the voltage while you move the piece into the bath.Still having trouble getting to the fabled green, even though we can get the voltage required for it. Probably something we're doing wrong that isn't related to the device, because this thing is a champ.Colors that are easy to get: light bronze, bronze, purple, blue, steel blue, slight hint of yellow, shiny gold, pink, purple againColors that are difficult to get: blue again, cyan, green
