Review: Orico DUB-12P, 12 port Phone Charger

Last review was about the Anker PowerPort 10, today we are stepping it up a notch and I’m reviewing the Orico DUB-12P a 12 port charger which officially supports up to 5v 20A or 100 watt of total output power! Definitely the most powerful USB charger I’ve ever seen!

Video review (Orico DUB-12P)

Check out the video of this very powerful phone charger. I’ll show you a bit of the packaging and accessories it comes with and the charger itself.

Package & Photos

The charger comes in the style box as the previous Orico charger, completely white with only the logo on the front and some information text on the back. I also uses the same slide out design and includes everything you need.

As I’ve said before, I really like chargers with a separate power cord and wide input voltage range so it can be used anywhere in the world. It also allows you to position the charger right where you need it, instead of having it hang from a socket somewhere.  It also means your USB cables don’t have to be excessively long! Speaking of USB cables, take a look at my review about different brands of USB cables here.

I bought this charger on aliexpress, you can do so yourself by clicking here.

P1000754This charger has so many ports! They are divided in two groups of 6. While testing, there is no continuity between both groups while there is within the groups so I suspect this charger is “secretly” two chargers in the same chassis

P1000770P1000772The standard 3x 5v 2A test yielded between 36 and 37 watt from the socket. 36 watt when using one port group, 37 watt when using both port groups. That would support the idea that this charger is really 2 chargers inside of one chassis. Drawing 36 watt would make this 83% efficient, a fine score

Orico DUB-P12Even while loading the supply with 10x 5v 2A it still showed above 80% efficiency!

P1000800The testing setup in full glory. I didn’t even have enough adjustable load’s so I needed to use some of those horrible thermal resistors. They don’t pull a full 2.0A like the adjustable one’s (About 1.8A) and get INSANELY HOT. Measuring them they got up to 180 degrees Celsius after about 5 minutes of testing, quite toasty as you can see in the last part of the video!

The charger was able to sustain this kind of load for at least 10 minutes though which is VERY good, basically, it should be able to handle just about anything you throw on it!


Single port tests

Port 1

no load p1One port loaded we see a good amperage which cuts off at around 2.7A and a fairly good voltage curve. I’ve seen it end up a bit higher using my testing setup but it’s not bad either

Port 2

no load p2No surprise there, port 2 shows exactly the same!

no load p7

And port 7 shows pretty much the same, just the amperage ends up a bit higher then on port 1 or 2 but the voltage ends up a bit lower. I don’t know why this difference is there.

Multiport tests

All ports fully loaded!

all load p1First up is the heaviest test I did, all ports loaded with 10x 5v 2A and 1x 5v 2A (Thermal load) and the EBD-USB connected to port 1. that makes 12 filled ports in total. Amazingly, even while drawing 150 watt from the wall socket the voltage or amperage this charger can deliver doesn’t change at all!

It also still only resets the overloaded port (above 2.7A) and not the whole charger during testing. This thing has some power!

11 port loaded total, port 1

10p load port 1So I decided to ditch the Resistor loads and only use the 10x 5v 2A variable loads I have. Adding to this the EBD-USB. That means 11 ports where used in total.

Port 1 does well, no real change visible

11 port loaded total, port 6

11p load p6Here we do see a change, it seems that at high amperage the charger cannot keep the voltage up. It still stays above 4.0 volts at all times though so it shouldn’t affect any connected devices too much.

11 port loaded total, port 12

11p load p12

Looking at port 12 during the same test we see it delivering the same amperage and just a bit lower voltage at 4.4 volt.


What an awesome charger! Basically, I could not get this charger to reset or overload with any reasonably thinkable load. Sure, I could turn up the variable loads to 2.6A each and at some point the charger would reset itself because of it’s overload protection, but I don’t know any device which would draw that much consistently much less any situation where you would have a few of those connected at the same time.

In a real world situation, there is always going to be a mix of output amperage’s. Phones and tablets ask for anything from 0.5A to 2.4A and so testing with 2.0A per port is already pretty much a worst case scenario and this charger chugged through it like nothing else!

But, if you have 12 iPad’s and they are completely depleted and all start pulling 2.4A at the same time…. this charger will do it! I repeatedly tested turning it off and on again and it started right up and supplied the load to all ports within a second. Very very nice!

During testing the unit did get quite hot. As can be seen in the video it reached a 100 degrees Celsius. Although I believe those measurements to be off. While touching the unit it did feel (very) hot, but it did not scorch my hands either.

  1. Great post, thanks! 🙂 I’m curious though to the internals of the Orico. Why not a few pics of the charger opened up? Let’s see the build quality… how safe is it? Will it last a couple of years with intense usage?

    1. I don’t tear them apart for two reasons. It’s a sample I bought myself and actually have a use for, so I’d like to keep it in one piece if possible.

      And second, even if I did open it up, I don’t really have the technical knowledge to describe the components inside or how well it’s made or not. So I’d rather stick to what I can do and know instead of maybe giving people wrong advice. That’s why I’m having Mux look at the Chinese power supplies in this:

      But it’s a good suggestion though and if my knowledge improves in the future, I will certainly do so! 😀
