Review: Great power cord for almost any device - Hey are you looking for a power cord for one of your favorite electronics and can't seem to find it? This thing can handle many different ports at different levels. It has adjustable power and many different adapters. I personally use it to power a Christmas decoration that has been with my family for a long time and has had no power cord since I discovered it. Now it shines bright in our house every year we use it. It is small, has a decent cord length and functions well.
Review: Flexible Charger - I have lost many charging cords but this system has been a great replacement including having the ability to change polarity. Very pleased and a rechargeable flashlight and handheld VHF radio are fully charged and back in use.

### ⭐⭐⭐⭐⭐ Great power cord for almost any device
*by M***R on May 7, 2025*

Hey are you looking for a power cord for one of your favorite electronics and can't seem to find it? This thing can handle many different ports at different levels. It has adjustable power and many different adapters. I personally use it to power a Christmas decoration that has been with my family for a long time and has had no power cord since I discovered it.

### ⭐⭐⭐⭐⭐ Flexible Charger

### ⭐⭐⭐⭐⭐ Universal AC Adapter with Reverse Polarity
*by D***O on April 24, 2022*

I've lost a bunch of my AC Adapters for numerous items. I like this AC Adapter since it is universal and allows me to dial in the right voltage that I need. It also can reverse the polarity, if I need that feature, too. A lot of AC Adapters do not have this feature, or, if they do, it does not seem to work properly. In summary, as long as your item does not need more than 2000ma, then this product will work perfectly. It is also priced right, another plus.
