      Basic package and components

      I was looking for an AC power supply unit, and there was only one option available, the Best Buy in house brand, with all of the included adapters. It was hard to find, and nobody was around to help, so I had to hunt someone down, who didn't know and had to ask someone else. The adapters are color coded, but they don't mean anything, so you'll have to guess and try which ones fit. It does what it says and supplies power, but there isn't an explanation for what the switch on it does, and the salesperson couldn't provide any additional information, other than "you shouldn't have to worry about that". The actual base is quite large and will hog an outlet from other plugs, but at least the prongs fold for storage and travel. The instructions aren't very helpful either, but it works as advertised. It was actually on sale from the marked price and rung up as $16.99 instead of $20.00, which was nice since I was using a gift card from Android Pay.

      Functioning better than anticipated

      This product is a replacement for a failed unit from years gone by. I was unsure if I would be able to use my external HDD case with my outdated, small-capacity internal HDD on my Dell OptiPlex GX260, (yes, you read that correctly), again. The GX260 is used primarily as my Diablo and Diablo 2 gaming system. Don't laugh; I love those games. My internal HDD is nearing capacity and this unit will power the external HDD with the hopes of making additional room on the internal HDD. I may just move Diablo, Diablo 2, and their expansion packs, (Hellfire and Lord of Destruction, respectively), to the external HDD and perform a fresh install of Windows XP on the GX260.

      I bought this because of a radio/cassette tape player that I had. With the different settings and the plugs I can use it on my other portable electronics. Easy to use and I’ve had no problems with it. There are two similar products this one and another one. Make sure to find out which one you need. There should be a polarity chart on your device product intstructions. And make sure that you have the right match to convert from 120 volts( house voltage) to the device. Mine is 3 volts. This product starts at 3 volts and has 5 or 6 increasing options. The other one I think starts higher. And the polarity is a little different.

      I had never seen this device before and had several of them from Radio Shack but since they have gone away and I need a couple more I got in the car and went to Best Buy to see if they had something at least similar. Turns out this one is EVERY BIT as good, if not better, than the ones I have from Radio Shack. The only reason for 4 instead of 5 is that it is not switchable polarity like the Radio Shack ones are but since it had the correct polarity for my devices that was not an issue for me. I could be wrong but I suspect that maybe the reason for it is that few if anybody actually makes devices with a negative middle post.

      does what it needs to

      it would be nice to have a dedicated voltage rather than a variable but alas it is challenging to find such a rare animal now a days so this was my next best option. it seems to resolve my issue with the transmitter since the original one started to fluctuate voltage wise and my signal was compromised. I would suggest if one is having 'troubles' with devices and an older transformer it would be a good starting point to check the power source. I had been having 'issues' for months and thought it was a wifi interference thing but it ended up being the 9 volt transformer had gone to 11.7 volts..... I trust this one will last the 6 years the old did.

      Very Useful as a travel adapter

      We were going on a road trip and I forgot to pack the power adapter for a DVD player we were going to use in the car. For a long road trip, this was not going to be a good situation so we stopped at the next large city, got help from a salesperson and bought this adapter. It was useful for not only the DVD player but other electronic devices we needed to charge into an electrical outlet! (I also bought a car charger to use with this tool, and am keeping both items safely packed in my travel back so that if I forget the power cord for various electronics, this can serve as my backup!

      Poor output strenght capacity

      Purchased the power adapter. Its body has a switch for selection of voltage output needed. Came with five adapter outlet cord ends for various insertion needs but still had to grind off the nearest one to fit so it would engage in the socket. Fired it up (an older Sirius boom-box) and it ran for about four minutes, then started fading. Power went completely missing. Let it cool off, fired it back up. Same thing again. So the power amperage rating output is insufficient for my need. Now I've got a power supply adapter for other needs if they ever arise. This one is not a strong unit. Would not purchase it again.

      This universal charger didn't work on my ASUS

      The Geek Squad recommented this power cord for my ASUS that I bought at Best Buy. Although I showed the computer to the guy, this power cord didn't work with my ASUS laptop which I found out later was an UltraBook. The ASUS computer didn't state that (Geek Squad recommended this computer). I went round and round with ASUS trying to get one from them. Back service from them, but finally I returned to Best Buy and another Geek Squad agent knew what I needed and that my ASUS was an UltraBook. No more ASUS for ME! I'm sure this would work for others.
