Sadly, the design does sacrifice some practicality primarily based on how individuals usually use a wall charger. As in plug it in and go away it plugged in.

What’s included with the GravaStar Alpha65 65W GaN Charger.


As I discussed within the Fast Take part, the GravaStar Alpha65 65W GaN Charger is kinda cute. Largely off-white in color, the entrance edge has a black part with two LED eyes that seem like a face. The LED eyes mild up pink when plugged in.

On both facet of the charger are two adjustable legs. When taken out of the field, the legs are compact, putting the charger in a “sitting” place. To increase the legs, it’s important to push down on the again prolonged piece after which pull the black ft all the way down to click on them into place.

The highest of the charger has three ports — an 18W USB-A, a 20W USB-C, and a 65W USB-C — and two tiny nubs. The nubs are the place you connect the included “ears” which slide on simply and are held in place by a tiny magnet. The again of the charger is non-descript, black in color, and has a few followers and piston-type designs on it.

Lastly, the underside of the Alpha65 is the place the ability plug is situated. Compacted by default, the 2 prongs (for our North American model pattern) snap downwards by pulling on them from the entrance. As soon as prolonged, you possibly can plug the charger right into a wall outlet or energy bar.

Herein lies the “not very sensible” feedback. While you plug the charger into the wall, it’s important to collapse the legs — which is minor. Nonetheless, relying on the way you plug it into the wall can have both the output textual content beneath every USB port the other way up or have the LED eyes dealing with down and never seen. I discovered the most effective spot for the charger was in an influence bar with side-facing outlet ports. With this, you might have the charger plugged into the ability bar, the textual content in the fitting orientation, and be capable of see the eyes lit up. Nonetheless, most individuals have their energy bar beneath their desks and, in consequence, you received’t be capable of see the charger there. Not solely that however when plugged into an influence bar, the cables then come out of the highest of the charger (which isn’t irregular) however look odd given the design.

Don’t get me fallacious, the design is completely different and cute, however I do assume that there’s some room for minor enhancements right here to make it work in each standing and sitting positions and whereas plugged into an outlet. Actually, I feel there would possibly must be two variations of this little man, one for plugging right into a wall outlet and a second to be used with an influence bar.

Ease of Use

Whereas the GravaStar Alpha65 65W GaN Charger is simple to make use of, it’s not a easy plug-and-play like different wall chargers. It’s easy sufficient, however when plugging it right into a wall, you do need to push the legs again down so the plugs match contained in the outlet. Aside from that, plug in your USB cable to the suitable port and away you go.


The GravaStar Alpha65 65W GaN Charger makes use of GaN charging expertise, because the identify implies. In case you’re unfamiliar with the expertise, it “delivers 65W [or higher] outputs with much less warmth and higher effectivity, charging units quicker and with extra energy, in much less time. The synchronous rectification chip additional improves the ability provide effectivity for a number of units like smartphones and laptops.”

That out of the best way, the Alpha65 does certainly output as much as 65W of charging, with a few caveats. You may obtain 65W charging if the 65W USB-C port is the one port getting used. If charging two units, you may get 45W and 20W (for a complete of 65W) if you’re utilizing each USB-C ports, or 45W and 18W if utilizing the 65W USB-C port and the 18W USB-A port. If utilizing all three ports, you’ll prime out at 15W for every port for a complete of 45W. That being stated, it’s not a limitation of the Alpha65 particularly, however simply the best way GaN chargers are likely to work with a number of output ports.

On that observe, the Alpha65 GaN Charger does output as acknowledged, and I had no points charging every part from laptops, Chromebooks, smartphones, and smartwatches with it. The laptops and Chromebooks, after all, required 65W or much less of charging energy.

Lastly, the GravaStar Alpha65 additionally options eight real-time protections together with overvoltage, overcurrent, quick circuit, overtemperature, overpower, beneath voltage, electrostatic, and anti-interference safety. The charger additionally includes a flame-retardant shell for protected charging. Whereas plugged in and charging, I didn’t really feel it getting overly heat and it’s good to realize it has onboard safety to forestall gadget injury.


Given the robotic design of the Alpha65, I used to be a bit stunned that it”s $59.95 retail value isn’t far off from different 65W triple-port GaN chargers. Most are available across the $50 mark, so so far as value/worth you’re solely paying a small improve for the funky design. That being stated, should you determined to preorder the GravaStar Supernova Bluetooth speaker (assessment coming quickly) earlier than April ninth, the corporate will throw within the Alpha65 totally free when bought from the GravaStar web site.

Sadly, this can be a powerful one as a result of impracticality of the design as mentioned above. Nonetheless, should you’re set on a cute little robotic GaN charger sitting in your desk whereas not in use, this man is the one for you.


GravaStar’s first foray right into a sci-fi-inspired peripheral that’s not a speaker is a good first begin. Personally, I’m not a designer however I do imagine that, whereas very useful, a number of modifications might be made to the design to make it a bit extra sensible primarily based on how most individuals have a tendency to make use of plug-in GaN chargers. Nonetheless, it’s kinda cute and undoubtedly bought individuals speaking once they noticed it on my desk standing up whereas not getting used for charging my units.
