7 customers mention0 positive7 negative

Customers are dissatisfied with the size of the charging adapter. For example, they mention that the casing is a bit large, the plug on the adapter is kinda bulky, and the cord is too short. That said, some say the USB connector is long.

"...The plug on the adapter is kinda bulky(about twice the size of your typical USB flash drive) so if the USBs are close enough together you won't be..." Read more

"...The casing of this USB a bit big, don't expect size same as regular thumb drive, this size may cause some issue if want to insert in stackable USB..." Read more

"Works as advertised. Fine for larger installs, but can be bulky for portable use." Read more

"...My only minor dislike is how long the USB connector is. I feel like it's hanging out of the port even though it's plugged all the way in...." Read more

6 customers mention0 positive6 negative

Customers are dissatisfied with the amps in the charging adapter. They mention that it does not output 3.5e1 amp, it puts out 12v but no amps, and it didn't have enough power for anything. Some say that the adapter has absolutely no power on the 9V/12V end of the cable.

"...and bright, and says “9V” and flip the switch, “12V”, but absoluterly no power on the 9V/12V end of the cable...." Read more

"There are no words for deception. This item does not even output 3.5e⁻¹ amp." Read more

"...a strip of about 20 white 12V LEDs (very small load), it now outputs only 4.8V to the barrel connector, and moving the switch doesn't change anything." Read more

"loved the idea but it didn't have enough power for anything kept glitching" Read more

6 customers mention0 positive6 negative

Customers are dissatisfied with the stability of the charging adapter. They mention that it wobbles and does not hold a stable charge. Some say that the adapter is a bit loose in their device and disconnects at the plug. The voltage sags about 300mA with 250mA load and the power flow is intermittent.

"...With 250mA load the voltage sagged about 300mA. The ripple was around 75mV with a nasty triangle top and square wave bottom, not even a rounded..." Read more

"...does not do voltage regulation, or the power bank does not provide a stable voltage...." Read more

"The plug adapter to 3.5mm is a bit loose in my device, and disconnects at the slightest bump. However, the voltage conversion works as expected." Read more

"my only complaint it that it's a lil wobbly on the input of my device but otherwise it's not given any trouble" Read more

Works well for what it is

Reviewed in the United States on July 2, 2023

Size: 5V to 12V/No DisplayVerified Purchase

I found it hard to find a decent 5v USB to 12 converter. This one seems to work well so far. I have 3 of them, the open circuit output voltage ranges from 12.4 to 12.63 volts. Seems like a large range, but these are cheap devices, probably just a switching step up converter. I cannot say how much current I can draw out of them, but I started using one to power a device that draws about 3/4 amp, and in parallel with a LiON battery as backup this converter was able to run the device and slowly charge the battery. So I'm thinking it's capable of 1 amp or so. For now I'm using two of them in parallel (via Y cable), and yes this is probably not designed for by the manufacturer. As you would expect, open circuit you get the higher of the two converter voltages, then under 3/4 amp total load (in parallel) they dropped to 12.45 volts. Not bad in my application as the backup battery needs min of 12.3 volts to charge. They don't get very warm and have internal LED that is green with no load, and red with any load so you can see when some current is being drawn when the LED goes red. I did originally plan on putting a 47uF cap on the output of each one hoping to smooth out the output when in parallel in case somehow they interfered with each other, but that doesn't seem necessary so far especially with the backup battery serving the cap function. Hope this is useful info.

Works great for my use case.

Reviewed in the United States on November 28, 2022

Size: 5V to 12V/No DisplayVerified Purchase

First off, I hate bright LEDs on power supplies and USB cables. The green led of this one isn't as bad some blue LEDs but it's still too bright. One star off for the bright LED.

I'm using this to power a HDHomeRun Flex 4 tuner. It generally hovers around 12 volts and 0.8 amps. Tried a couple of 1 amp supplies and the tuner just didn't like them and I wouldn't get some of my local channels. Was looking for a higher amp USB power supply and couldn't find much out there. Guess 12v1amp is pushing the USB spec. Thankfully this one delivers 1.2 amps and HDHR tuner is fine with it.

I'm using an Anker multiport USB power supply to power a RaspberryPi, USB antenna booster and the HDHR. The USB supply is designed for 3+ amps out each port at same time. So the DROK step up converter is doing fine. If your trying to power it with a cheap phone charger, your results may not be as good.

My goal was to mount the antenna stuff, Pi and hard drive on small board and hand it on a wall in the garage. Not have it be an eye sore and still be compact. The DROK supply help to not have a wallwart blocking a power outlet.

This worked great for 3 years of use then finally today it gave out.

What I used it for: I wired this into my security camera so I could plug it into a solar powered battery bank or just a usb plug. It survived temperatures up to 120° F in the desert.

Overall opinion: it's very worth it but expect it to die one day suddenly for seemingly no reason.

Very poor performance compared to some others I tested

Reviewed in the United States on October 25, 2020

Size: 5V to 9/12VVerified Purchase

I had high hopes. I really like this brand and have had good luck with other products from them, but not this one.
I bought similar products from several brands then measured them for voltage regulation and ripple using an electronic load, scope and volt meter. This one was the worst performing of all of them.

With 250mA load the voltage sagged about 300mA. The ripple was around 75mV with a nasty triangle top and square wave bottom, not even a rounded typical wave (discontinuous mode artifacts?) at about 400KHz. The competition was around 1mV PP rounded wave at 3MHz at a similar load with under 10mV of voltage sag.

This might be good for non critical applications but clearly for anything that needs clean 9 or 12V there are way better products out there that do this for less $$$.

Works as advertised and is fairly accurate as it tested within .1 volts on both 9v and 12v settings. I would have given this 5 stars based on voltage accuracy, but the materials are ridiculously cheap, really cheap. Would have gladly paid double the price for better quality materials.

Works perfectly within the given specifications

Reviewed in Canada on September 16, 2018

Size: 5V to 9/12VVerified Purchase

I own two of these units, purchased about two months apart. They deliver the specified power, if you have a device that drops out the surge demand or continuous demand may be too much (too many amps) or the parent USB power supply is too low (delivering under 2 amps at 5V).

I use mine to power a 12V 0.1-1A telescope motor, 12V fan that needs .8A and 9V 1A HDD toaster.

No complaints! It works as long as the power supply (USB port) and load demand are within the range of the converter specs. For a little more amperage I've used a USB C to USB 3.1 adapter to deliver 3A into the unit from a power bank with a USB-C port. In testing this allows the converter to deliver about 1.3A at 12V.

Bottom line - it works but it's best for low amperage devices with minimal surge requirements.
