It's been a great little power supply!
Style: 5 Amp
Pattern Name: Power Supply
Bought this in 2018. I may have reviewed it right away. So this is an "After Six Years Of Use" review. I wanted to mount it in an ammo can, so I moved the fuse to the front, and moved the rectifier and heat sink to the side of the unit. Then I mounted it in an ammo can. I had to file off the top of the fuse holder and remove some plastic from the + and - connectors on the front panel; I had to do that in order to close the lid of the ammo can. I added various cords and connectors for a wide variety of applications. I paired it with a VHF/UHF radio in another ammo can (with a battery pack) for a great disaster prep radio combination! I've been using this setup as a VHF/UHF base station on top of my HF radio cabinet for 6 years. No complaints, no issues. It's been a fantastic little power supply, and I've even used it to power my Yaesu FT-817 HF transceiver on many occasions. Two Thumbs Up!

Pyramid PS9KX 12V Power Supply - a definite BUY, quality construction, adheres to advertised specs
Style: 5 Amp
Pattern Name: Power Supply
This is a review of the Pyramid PS9KX 12V, 5amp Power Supply. Made in China but built like a tank (the housing is made of steel as you might expect. It has a 12V Cigarette lighter receptacle plus a set of screw terminal (+/-) connectors. I use it mainly to program settings for dashcams b/c I hate having to dismount them or break my neck to view them on windshields - usually in either very hot or cold vehicles at that. It's really nice to do that programming while sitting on my living room sofa or at my workbench. Of course, you can use this unit to charge/run any 12V devices, with the proper connector. The receptacle and screw terminals have an advertised output of 13.8V (I verified my output at 13.78V on both - close enough). The power cord on my unit is 51 inches long and is the only shortcoming (no pun intended) of the unit - I'd like to have had an 8 foot cord; otherwise, I rate this power supply as a definite BUY. The manufacturer boasts that this power supply has: 1) over temperature protection, 2) short circuit protection, and is 3) fused. It runs on 115V AC 60Hz and draws 70W. It’s rated at 5A constant, 7A surge. It has a nice heat sink on the back side which appears to be aluminum. It has beefy, rubber feet to hold it steady. My unit weighed 4lbs. 3oz (1.9kg), excluding the power cord.

POWERED ON/ BACK TO THE FUTURE
Style: 5 Amp
Pattern Name: Power Supply
Great to safely test my MOTOROLA DYNATACS from the 1980’s and early 1990’s. Selling on Ebay as Claimitamerica- this power supply has helped me awaken over 30 year old early cell phones and become #1 in GOOGLE search. This is a solid/ well built unit. The pictured phone is DYNATAC 8000M from 1992 with only 792 minutes of use and looks like new. Since the batteries are over 30 years old, can’t compare to running off this power supply. It also has a great car socket to use with any 12V negative ground device and great with this PHONES slide on car adapter. Worth the price for this niche DIY product.
