## Description

Parameter Input: AC 100V~240V 50/60Hz Output Voltage: DC 3V~24V Adjustable Output Current: Max 3A Output Wattage:Max 72W Output DC connector:5.5mm x 2.5mm (inside"+", outside"-") 14 Tips Size: 6.5x4.4mm+Pin, 5.5x2.1mm, 5.5x3.0mm+Pin, 5.0x2.5mm, 6.3x3.0mm, 5.5x1.7mm, 4.8x1.7mm, 4.0x1.7mm, 3.5x1.35mm, 3.0x1.1mm, 2.5x0.7mm, Micro-USB, Type-C and DC terminal connector. Power cable length: 6ft / 180cm Safety Compliance: FCC / CE/ RoHS / CCC Working Temperature: 0~40℃ Storage Temperature: -40~85℃ Ambient Humidity: 5~95% Non-Condensation Weight: 0.66 lb / 300g Professional advice from licensed electrician: The max use should be no more than 80% of the full loads. Otherwise, the power supply will generate much heat and its service life will be greatly shortened. We recommend you to use this 72W power supply to power devices less than 58W. Package included 1x 72W Universal Power Supply Adapter 14x DC Tips 1x Reverse polarity converter cablePlease read before placing order！ This is the latest upgraded version of adjustable power supply！ Based on hundreds of users feedback, we have made the following improvements: 1. The knob can be adjusted more evenly, and it can reach 7V ~ 8V by rotating 50%. 2. Increase the off gear to turn off the power without pulling the plug. 3. Add a polarity converter cable, which make it compatible with more devices. 4. Correct knob label, "Min" being 3 volts and 12 volts being "Max”. Kindly note: Some user complained that voltage will change slightly without adjusting it. In fact, this is normal when your device is working. Besides, ambient temperature, magnetic field, signal noise will also affect output voltage. But the change is slight and acceptable. It will not damage your electronics.

Review: It does what you want and does it very well, but also gives you so much more for the money you pay. There are plenty of advantages over your standard Wall Wort type Power adapter, among which are: You get a digital display that shows the DC voltage output value, which is also what you use to set the desired output voltage level. The potentiometer is very smooth and not too tight, such that it's easy to achieve the actual voltage value you need. The output voltage is accurate to what is displayed on the display of the power adapter, and also it's easier to use than many of the standard AC/DC power adapters in that you have a long cord that gives you a nice tight plug to use to plug into the outlet verses several other Power Adapters on the market what contain the transformer within the plug that you plug into the outlet source. The vast and large selection of adapters that are included with the power adapter also mean that this is a multipurpose Power Adapter that you can use with several different devices requiring many different plugs. This means you only need one adapter rather than one for each device, or you have one adapter that works across several other devices. As long as you specify the correct amperage sufficient to operate all your different DC devices, you only have to make one purchase rather than many different ones.

## Questions & Answers

**Q: It stopped working, when a device is plugged the digits start blinking. What is happening?**
A: Probably a fuse on the load side.

**Q: Do you think I can use it , to charge a motorcycle battery and or “ trickle charge “ ( maintain) a car battery?**
A: You would need some electrical experience and battery charger know how and wire in an amp meter to insure volts times amps does not ever exceed the safe rating of this device.  Also need to insure the voltage does not exceed safe voltage to charge a battery at. If you know how, I think it could work for lead-acid batteries but probably not other rechargeable batteries. I recommend instead to use a dedicated battery charger designed for what you are doing.

**Q: Will this accept the adapters with a 5.5mm x 2.1mm dimensions? I ask because the images show the plug to be 5.5mm x 2.5mm and 2.1 seems to be standard**
A: The product description says,
Output DC connector:5.5mm x 2.5mm (inside"+", outside"-")
Reverse polarity converter: 5.5mm x 2.1mm

**Q: Will this work and is it safe for a device with 120vac 60hz 5w input and 16v 100ma dc output?**
A: Hi,
The 3V~24V 3A power supply just power any device which its input voltage is between 3V and 24V, and input current is equal or less than 3A.Thanks.
