Zolt 45W Universal Power Adapter AC DC 5V 6V 7.5V 9V 12V 13.5V 15V Power Supply Transformer Adaptor for Household Electronics, 3A Max.

No micro usb adapter included, despite being listed in the description.

I bought this to replace a gaming chair PSU that was lost and it provides ample stable power at the required 9v 3A. It has also come in handy for powering up an old Windows 8 tablet that had a misplaced power supply and a VR headset stand also with a missing power supply, (thanks to the useful interchangable connector tips). The only problem it gave me was it couldn't power a Pi3b+ at 5v 2.6A without a few voltage warnings so I can't recommend it for that without testing for longer. If you want a PSU for a Raspberry Pi 3 or newer I would go with a genuine Nintendo Switch PSU to be sure, I have not had any others work 100% for that but for most other devices that aren't so fussy, this PSU will suit you well up to 15v 3a. i do recommend this item if you need to charge an old laptop or have a missing charger, however

This is going to save a lot of money. I use it to power a RA motor on one of my telescope mounts, which uses 4 D cell batteries at up to £10 a go. Using this power adapter will literaly save me £100`s a year. Even if it only lasts 3 months it is still worth it. The output voltage is constant and although it adds to my electric bill, at 45 watts, I would have to have it running continuously for 67 hours to use the same amount of power as my oven uses in 1 hour. And a lot cheaper than a pack of batteries every week. (Weather permitting). So well worth it. And it wont go flat in the midle of a cold winters night.

Rapid delivery. Appears and feels like a quality item. Key provided for easy manual voltage adjustment. PVR working perfectly again.

Got this to replace my dads power supply to his portable speaker. It required a very specific jack size and voltage combo and this had both. I chose the brick deisng instead of all being on the plug for longevity and easy plugging in as the other design are a bit bulky. It worked well with my only gripe being the barrel jack was a little tight in the speaker due to tolerances. Not a deal breaker though and it charged up nicely. Well worth the money.
