Review: Nice units and work well within limits - Nice units, They don't feel like they will fall apart anytime soon as some alternative devices I looked at reviews of are reported to. The 5.5 2.1 to 2.5 plug adapter is a nicely made unit too and in my head it's worth a £1 or 2 on its own ! I bought 4 of these so I hope that counts as a reasonable sample to test. I did see a small variation in maximum power output between them on test but nothing too bad. Looking at the figures for the 'least powerful' of them (obviously others test methods and results may vary etc etc ) they produced about 9.25Volts (highest 9.35) without load and all stayed above 9V as the load was applied and increased to 0.5A After that I saw 8.4V (still fine for many 9V devices) with 0.6A drawn and then down to 7.3 V with 0.73A drawn. For the very best of my 4 units the final result was 7.7V with 0.78A drawn (with 5.08V @ 1.48A going in) I didn't take it further but I did leave the least powerful one delivering 0.73A for 3 minutes with no significant noise or heat building in that time. So this works well for producing 9V up to around 0.5A (500mA) and with a good bit left in reserve for heavy initial current in lights /chargers etc. For what they are and the excellent price I'd say these are a useful problem solver for things like device chargoing in the car etc
Review: Seems to work well after quick test! - This device works well so far. I've only briefly tested it with four 12v fans with a current draw of 0.08A each. They're pulling a total of 0.37A consistently when powered using this cable and a OnePlus fast charger which can provide up to 5A. Will report back when I've tested it using different power supplies. Listing says it needs a minimum of 2A to even work so I'll see if that's true. It does get noticeably warm in my use case but so far doesn't seem to be overheating when given sufficient power, some heat dissipation is normal given the job its doing. Connector seems stable, cable seems fit for purpose. I don't think this circuit is a difficult one to manufacture but to get a reliable one that doesn't overheat, ya do have to spend a few more quid. Avoid getting those 10 x boost converter module packs as they tend to overheat massively and can output very little current. Would recommend this cable so far!

## Features

- 【USB 5V to DC 12V Cable】Because the USB input is 5V 2A male, please make sure the current is 2A or the device may not work. The DC output is 12.0V and the max current is 0.6A. Note: NOT suitable for high current equipment
- 【PLEASE NOTE】Our products themselves are DC5521 connectors, but each of our products comes with an additional DC5521 female to DC5525 male adapter. With this adapter, the DC head section of this product is also DC5525 male. So this product is compatible with both sizes. Please check if it fits in the power jack on your devices
- 【Safe & Reliable】As built in upgraded intelligent IC circuit, our voltage adapter provides your devices perfect protecetion from over-current, over voltage, overload or short circuit
- 【Widely Usage】 It is super convenient for different kinds of devices such as fan, table lamp, bluetooth audio, wireless router, speakers which requires for 12V power. Useful for powering the WiFi router via a power bank or other 5V power source during power outages. Can also be used with other devices that require a 12V power supply
- 【100% Guarantee】We provide18 months warranty and lifetime customer service. Please contact us at any time if you encounter any issue and we'll make it right

## Questions & Answers

**Q: Will it power a guitar pedal?**
A: Caution: I read the answer above and so bought a couple of cables. I tested them on receipt to find they are centre-positive.  All of my Marshall, Boss and most other pedals I own and Roland street cube and such are centre-negative... that is to say the positive terminal is the sleeve.  I think one of my Zoom pedals,  and my Arturia Keystep are centre-positive.  So you should check your pedals/devices polarity before buying these. There are polarity reversal leads here on Amazon. And it's no "biggie" for me, I'm just going to chop the cables and reverse the polarity... but I guess that will invalidate any warranty.  The voltage was 9.17v, which I rate as excellent for such a low cost product.

**Q: what is the output current rating**
A: I don't know the maximum but the device I power draws 800 ma-1000 ma and I have had no problems.

**Q: Would this charge a dab radio?.**
A: If it's 12v then yes

**Q: Is the inside diameter of the 12v system dc jack 2.5mm or 2.1mm. Thank you.**
A: It’s 2.1mm internal diameter and the output is 9VDC centre positive

### ⭐⭐⭐⭐⭐ Great for using devices that would normally need a mains power supply!
*by A***Y on 28 January 2024*

I work with network equipment and often have to use small Netgear switches or media converters in racks or whilst moving about. There are often no mains sockets available. This lets me power the switch or media converter from my laptop, or even a convenient USB port on the equipment itself, like on most Cisco gear. You do need to check it won't pull too much current, but it's fine for most reasonable use cases. Robust enough as well. Maybe my only complaint is the electronics are all in the plug, which is quite deep. This sometimes means you can plug it or leave it plugged in with limited space. If it was in a blob on the middle of the cable, you could do this. I tried another type of this cable before and it was not nearly as robust or stable.
