(Last Updated On: June 3, 2023)

Power Delivery chargers have become much smaller over the past few years, thanks to GaN tech that enables a charger to be smaller and still able to deliver lots of charging power. In this review, we’re looking at a next-generation PD wall charger from AOHI; this Magcube 30W wall charger is one of the smallest 30W wall chargers you can get on the market. The charger is even smaller than Anker’s smallest GaN 30W wall charger.

Outputting 30W and being the size of a quarter is insane; we’ve never seen or experienced anything like it.

Charging Power

There isn’t much to say about the AOHI Magcube wall charger charging because it only has a single port, but the single port is impressive because it has a 30W power output. With a 30W Power Delivery charging speed, you can charge most laptops, such as Macbooks and Chromebooks. When it comes to laptops that require more charging power, though, it’s best to go with a higher PD charger for laptops such as the ones from Lenovo.

This Magcube charger could charge a Lenovo Flex 5 laptop at a slower charging speed than the original charger.

However, when we charged a Microsoft Surface Go, a tablet PC, it could charge at its max speed of about 20W to 25W. We could also fast charge a Samsung Galaxy Note 9 and an iPhone 11 Pro Max with a Magcube wall charger.

Size and Weight

The size of this AOHI wall charger is one of the best parts when you combine it with a 30W charging speed. That’s because the charger has 1-inch dimensions all around; to add to that, it only weighs about 2 ounces. As mentioned, the charger is the same size as a quarter, as shown in the above image.

Functional Components

This Magcube wall charger has a different design than other chargers, with the front having a heavy engraving pattern design.

The charger does not have a foldable plug, and that’s no problem considering how small the charger already is. Once you plug it in, there is a Green LED light at the front when nothing is charging or trickle charging is happening with lower-powered devices; when a device is fast charging, the Greenlight turns into a dim Yellow blinking light. The light turns blue for standard charging.

Build Quality

The charger has a great build, and you don’t have to worry about it getting damaged even if you place it into a bag with other belongings.

The charger only gets slightly warm during charging, and that doesn’t come as a surprise because the size is so tiny, and heat will always be generated with a charger. The GaN+ tech does a good enough job to lessen the heat generated.


AOHI also makes this braided 100W USB-C to USB-C cable that has a premium build

If you have a USB-C chargeable laptop and a smartphone that you can fast charge via USB-C (which you likely do if you own a USB-C Android phone or an iPhone as those are Power Delivery compatible), then this AOHI Magcube wall charger can be reliable. However, the 30W PD charging is incompatible with the fast charging of all USB-C laptops, so if you want to make sure you can charge your laptop fast, we recommend that you go with a higher Wattage charger. AOHI will be releasing their new ones soon.

This 30W Magcube charger did come in handy when charging a tablet at max speed, though, and the small size is great if you want a charger that you barely have to keep track of.



Charging power is pretty good, but at this point, 30W can cause some limits to be reached with certain USB-C laptops. It’s still great for charging certain laptops and perfect for fast charging tablets and smartphones. You can only charge a single device with this wall charger, though.


This is one of the smallest 30W wall chargers you can find on the market. It’s about the same size as a quarter.


The charger is strong, and you don’t have to worry about a foldable plug breaking. It does get a little warm during normal charging, especially for such a small charger.


The charger may not charge all USB-C laptops, but it can charge most and fast charge tablets and smartphones. The small size enables you to take this charger anywhere you want easily, and it will likely be the smallest charger you’ve ever owned.
