AllMaybe Dual USB Wall Chargers - Standard (EU2-ST) and Quick Charge (EU2)

Unboxing

Since i got both variants of the charger, this will be an unified review with detailed comparisions.

Photos Order: Standard variant on the left, Quick Charge variant on the right.

Compared to the desktop charging station reviewed a while ago, this new wall charger doesn't come with many accessories: 1x User Manual with a nice specs sheet, 1x Warranty Card and the Charger (of course). No USB Cables included.

Both models share the same chassis, only the color is different: Black for the Standard variant and White for the Quick Charge variant. It feels solid and there are no annoying glossy parts that can get dirty and scratched really easily.

On one side, there is the LCD screen (more details in the next paragraph) covered by a plastic surface. This surface doesn't look 100% new even after removing the protective film, and is also easy to scratch, so be careful with it (of course this doesn't mean that all units face the same issue, but it is still worth to be reported).

On the side opposite to the power plug (that is foldable), there are 2x USB Ports (with a small marking above each port, "QC 3.0" or "2.4A" depending on the model) and a button required to switch the measurement between each port.

As regards the size, it is probably the most compact dual-usb wall charger i have ever tried, just 62.4x55.0x2.82mm (same for both models) with a weight of 87g for the Standard model and 101g for the Quick Charge model. Of course the latter weights more since it is the most powerful.

Efficiency and Power Meter

Since i am mad when it comes to power efficiency and real output power, i got a crazy USB tester some weeks ago to stress all chargers and cables i own to the max. Of course both of these chargers will receive the same treatment. ^^

NOTE: In order to make sure that the built-in power meter is accurate, each test has been made using also my reliable high-quality USB tester.

As you can easily notice, the screen shows the USB port currently selected with voltage output, current output and the amount of total current drawn since its connection to the socket. Also, it features a nice blue backlight that can be dimmed by long-pressing the button, definetely a plus compared to standard chargers.

Starting from the no-load test (on idle), the voltage appears to be quite stable, maybe higher than usual for the standard variant, but still OK to comply with USB standards.

Stressing both chargers to the maximum rated specs (5V/2.4A for the standard variant and 5V/3A for the Quick Charge variant), the result is quite impressive.

The Quick Charge variant reached a voltage of 5.15V under 3A of load, and the Standard variant reached 5.21V under 2.4A of load. Excellent results, definitely able to handle high resistance (high AWG) USB cables.

Considering the excellent result i thought...what about stressing each charger to the max? Well, since the Quick Charge variant is already maxed out (don't want to go over 3A for safety reasons), i did this test only with the standard variant, by increasing the load over 2.4A. The maximum it can reach without tripping the overload protection is ~2.78A while keeping the same voltage of 5.21V!

A test dedicated to the QC 3.0 variant is, of course, the test made using a Quick Charge capable device connected to it. Both my smartphone (LeEco Le 2) and power bank (iVoler 10000mAh) managed to use the Quick Charge capabilities of the charger, no compatibility issues noticed even with other devices.

As regards the noise level, i wasn't able to hear any buzzling noise (or high-pitched sound) even while doing the extreme test so i can confirm that high quality components have been used.

Conclusions

It is nice to see that AllMaybe followed user feedbacks and tried to provide one of the most complete wall charger i have ever seen. I am not sure whether the idea of placing a power meter is unique or not, but it is really useful and reduces the risks to connect a device with a poor USB cable, that would result in unstable battery charging or, even worse, permanent damage to the cable or device connected.

Honestly, i am not able to find any serious issue with any of these chargers. Based on the user's needs, it is possible to choose the variant required with or without Quick Charge, and the power output is just perfect. Maybe the only thing i would appreciate with next models is the inclusion of at least one USB Cable (Micro-USB + Type-C, 2-in-1 variant), and why not, a multi-usb charging station featuring the same power meter.

So, do i recommend them? Yes, with no doubts. Just choose the one that fits more your requirements, even though the Quick Charge variant is always the best choice, being future-proof ;).

Pros:

- Excellent Power Output

- Useful and Reliable Power Meter

- Overload Protection

- Quick Charge support (for the EU2 model)

Cons:

- No EU plug variant available

- Easy to scratch LCD plastic surface
