Belker 45W Universal 5V 6V 7.5V 9V 12V 13.5V 15V AC DC Adapter Power Supply for Household Eletronics LCD LED Strip Light Router HUB Speaker Smart Phone Tablet - Support Amps 0.5A 1A 2A 3A 3000mA Max.

had a cold water circulator for after knee surgery but couldn't find the power supply. 7.5 volt with small plug. this works great. a little overkill but its been running 6 weeks without a problem. the OEM replacement power supply was way higher price if i could find one. this will be very useful even after i quit using the machine.

Looked and looked for a power supply that would do 13.5 VDC and this did the trick. Powers my fiber based internet board.

I needed a charger for a wifi speaker which took a very small pin adapter which none of my usb cables had. This charger came with so many adapters I would be surprised if I ever needed anything else. The value , quality, and shipping from this vendor is outstanding.

Provides multiple tips and multiple voltages. But has a fixed polarity DC positive pin. The cord is decently long and the adapter itself is smaller than a laptop adapter but bigger than a wall adapter.It has been powering an elliptical that had its adapter lost during a move. It has had zero problems powering the panel, fan, brake and processor of the elliptical.The voltage output isn't terribly accurate at ~5% off. Compared to name brand adapters running 0.05% variance. I wouldn't trust this adapter with any kind of highly sensitive voltage requirements. A short device life would be the result. I would have been much happier to see this at around 2% or lower but its not like they are building these with quality in mind. They are built to a low price point.If you want better voltage tolerances, spend more and get O.E. Otherwise, this multipurpose adapter should do the trick for most needs.

WORKS GREAT!

I purchased this item in order to recharge my smart jump starter, as of now it works properly. The fact that it also includes extra plugs from different shapes and sizes is a plus.

For those times when you have an item that's lacking its original power supply unit, you'll likely need something like this. Has most every size power supply adapter plug... even one for just splicing in a wired connection! Very impressed with its steady output and the fact that it automatically adjusts to amperage load no matter what voltage you set it to. Only minor irritation is that it requires the included "key" to change the output voltage. Other than that, it's proven to be really good power supply!

I can not tell you how scary this was for me yesterday. I specifically ordered this charger for my air pump because the specs matched up perfectly. Even ran it by my husband. Once I got the charger I plugged it in and put it ant the right setting for my pump. Within 30 minutes I started smell something like burning plastic but didn’t think to check the pump. After an hour the smell was so intense I went on a hunt. Once I got to my air pump it was so hot I couldn’t even hold it without burning my hand. It was literally smoking. And the inside were melting out and splitting open the plastic casing. Had I left it any longer I fear it would have caught fire and my kids and I would have been in danger. I am beyond upset about this and warn you to not get this product as it is not compatible with everything they say it is! Thank god I didn’t plug it into charge and leave the house. I’m not sure I’d have a home if I had. Sounds dramatic but it’s actually real truth.
