Instructions on how to choose a suitable adapter: 1. Check Voltage Please find the spec label of your device and check the working voltage. It should be among 3V~24V DC, not lower than 3V or higher than 24V DC. Otherwise, your device will not work or be damaged. 2. Check Current Check the max current your device will draw. It should be equal to or less than 3A, such as 1A, 1.5A, 2A, 2.5A, 3A. Otherwise, your device won’t work well and the PS will be damaged very soon. 3. Check Plugs Check the power input port of your device. The PS is equipped with 14 pcs frequently-used DC tips. Please confirm wether it fits for your device before buy. If you can 't confirm, please measure it with a ruler. 4. Check Original PS If you have a original power supply for reference, their output voltage, plug size, polarity should be the same . If our PS’s current is equal to or higher than original one’s, then our PS will work with your device.

It works
Style: 3~24V3A 72W
I lost the power cord to an old Hi-8 camcorder and needed a way to power it on to save the old videos. This has tons of adapters and you can turn the voltage to whatever you need

Ok for the price but I’d get a bench model for serious use
Style: 3~24V3A 72W
I mainly bought this to use for projects when I need a certain voltage or plug and don’t have the correct spare power supply in my junk box. So far I’ve only been using it for a 19v 32” TV. I’ve noticed the voltage decreases all the way down to 17v sometimes when in use. I realize the load increases when turned on, but disconcerting this can’t hold a consistent voltage. I would pay the extra money and get a bench top model if you’re doing any serious testing ... show more

Indispensible tool for tinkerers
Style: 3~24V3A 72W
This adapter is a godsend for nerds, troubleshooters, and tinkerers. Great for testing small devices without carrying a sack of adapters with you. You can even bring it to Goodwill or other thrift stores to test small electronics on site prior to purchase. The voltage does fluctuate slightly over longer durations of use but the convenience wildly outweighs that minor issue. ... show more

Very handy to have! Voltage and Amperage seems accurate. I recommend it for the price.
Style: 3~24V3A 72W
I really like this handy power supply. Good variety of connectors, and the alligator clips are very nice to have. Very handy digital readout. I use this as a basic power supply when not at my bench, and for powering breadboard projects. Price is good, quality seems good also.

Worked great.

Came with everything I needed!
Style: 3~24V3A 72W
I was pleasantly surprised that it came with pretty much every plug adapter I could ever use! I have so many electronics that run off of various voltages and can never seem to find the correct wall wart. This solves that problem! Just be careful to make sure it’s turned down when you power up or you may spike too high. ... show more
