  • 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

  • Love the adjustable wattage
Style: 3~24V3A 72W
I just wish the adapters fit a little tighter because it comes unplugged very easily but overall I like the adjustment on the amperage or the wattage

  • 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.

  • Convenient for only one use or multiple
Style: 3~24V3A 72W
I use it to charge a Skullcandy barrel xt. Cheaper than OEM charger with a higher quality. The 5.5mm barrel is so universal everything uses it. Being able to dial in 3-24 v is easy. Very sensitive though. Charges quicker than OEM with same specs. I haven't noticed any whining from it mainly because I play bass music from the speaker when it's on. ... show more
