30W Universal AC to DC Power Adapter Adjustable Power Supply 3V 4.5V 6V 9V 12V 2A 1A DC Adapter AC 100-240V to DC 3-12V Multi Voltage Switching Power Adapter with 15 Tips + Polarity Converter

Good choice for a replacement power supply.

Works great

Great accessories to use with the power supply to fit any application

This is perfect for what I needed, only thing that knocked off 1 star was the fact that there was no paperwork/booklet of any kind with the charger. Love the ability to turn the volts to desired level.

Very good product the other one i had used to get warm while using these work great

This AC adapter feels lightweight and cheap. Not like the solid one I grew up using. I wish there were more well built products on the market these days. On the plus side, it has many options/connectors.

small quite compact unit. should do the job it's needed for.

This 24w power supply is compact - only 3 1/4" by 2". It has a non-polarized plug which makes it easier to fit into a wall or power strip. It is light weight and does not waste energy as it uses a filtered and regulated switching power supply. A small blue LED serves as a power indicator. The output connector is + positive on the inside and - negative outside. To reverse polarity use a short connector cord. The broad selection of connectors should accommodate any modern electronics including USB devices. A standard USB socket is located on the power pack next to the cord. The output voltages seem to be accurate. The 9 volt setting gave 9.18v unloaded and 9.0v loaded. The tested unloaded voltages were-- 12.3/9.18/7.6/6.04/5.32/4.5/3.07. The USB socket was 5.12v and supports 2.1A.

Compre el adaptador para revisar si una de las puntas le quedaba a esta balanza electrónica Ohaus que no viene con el adaptador correspondiente, estoy más que contento porque una de las puntas le quedó a la balanza y pague $298 en lugar de $1400 que costaba el original con una empresa importadora aquí en México. Así que, ya me olvide de las 4 pilas AA que necesita la balanza para funcionar, en mi caso recomiendo al mil este adaptador!

This does not buzz at all, which means it works perfectly for my headphone amp (after using the center negative adapter). The adapter that was included with my amp made an awful buzzing sound, but this replacement is completely silent.

J'en ai acheter 4 et les 4 fonctionne très bien depuis des mois et vous pouvez changer de voltages que vous désirer

Great little adapter, Bought it for my Panasonic Shockwave, and only discovered it also has a USB charging plug built in. I wish that much attention to detail went into it when judging the length of cable needed,.. really short cord, which is why 4stars not 5

It took several tries but we finally found a suitable power adapter for use with our various electronic devices. This adapter offers adequate power (2A, 30W), a wide variety of inter-changeable plug tips and even a polarity reversing cable, which is often excluded by other manufacturers and/or available as as a separate cost add-on accessory. Based upon our previous bad experiences with power adapters of insufficient amperage which led to the shut-down and/or malfunctioning of our digital musical instruments this adapter provided satisfactory power for several hours of use without any issues. We especially like that the different voltages can be selected easily and securely without the use of a separate losable tool. Our only concern is that unlike other similar power adapters, the weight of this one is extremely light and so we have concerns over its longevity. Other than this, this power adapter has it all, and was the ONE for us!
