ALITOVE 30W Universal Power Supply 3V 4.5V 5V 6V 7.5V 9V 12V Adjustable Variable AC/DC Adapter with 5V 2.1A USB Port, 100V-240V AC to DC 3V-12V Converter 0.5A 1A 1.2A 1.5A 2A 2.5A Max with 14 Tips

Input voltage ranges from AC 100V to 240V, with a current of 0.25A and a frequency of 50/60Hz. The output voltage can be adjusted to DC levels of 3V, 4.5V, 5V, 6V, 7.5V, 9V, or 12V, with a maximum output current of 2.5A and a maximum wattage of 30W. It includes 14 different tip sizes: 6.5x4.4mm with pin, 5.5x2.1mm, 5.5x3.0mm with 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 a DC terminal connector. The polarity is positive inside and negative outside. A reverse polarity converter is available for the 5.5mm x 2.1mm size. The adapter dimensions are 3.1 inches by 2 inches by 1.2 inches, and the cable length is 4.9 feet.

Superior Safety Flame-retardant exterior shell and built-in safeguards to protect against overheat, overload, over-charging, short-circuit provide ultimate protection for you and your devices.

Stable Output Built-in advanced synchronous rectifier smart chip and EMI filter, convert fluctuating voltage to stable voltage, effectively reduce electromagnetic interference, ensure stable voltage output.

High-quality Cable 2x 0.5 mm²(20AWG) copper conductors, individual wire insulation and flexible flame -retardant PVC jacket provide you a safe and reliable cable with better conductivity.

Reverse Polarity Converter Comes with a 4cm long reverse polarity converter for more devices,before using,plz distinguish the polarity of your devices first,otherwise it will damage devices

Broad Compatibility Max 2.5A ouput means it can supply with amperage less than 2.5A. ---such as 1A, 2A,2.5A. If your device requires 2A, 2A will be supplied. But if requires more than 2.5A, only 2.5A will be supplied.

Expanded Application We especially add a female terminal connector in the package. You can screw wires onto it to power the devices that have no female DC socket. This will greatly expand its applied range.

Professional Advice We suggest the max use of power should be no more than 80% of the full loads, otherwise,the power supply's spanlife will be shortened. We recommend to use 30W PS to power devices less than 24W.
