  • 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

  • Does the job, but hard to set exact voltage
Style: 3~24V3A 72W
Works well and the huge variety of DC connectors is great. My only complaint is that the voltage adjust control is very sensitive making it difficult to set an exact voltage. If it had a multi-turn potentiometer it would be perfect.

  • 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
