WARNING. This product is not electrically correct. As many have noted using outlet testers the NEUTRAL and HOT are reversed in this product. I have personally confirmed this with a multimeter voltage test.
A swapped hot and neutral will operate correctly but can have minor to dangerous consequences. In the worst case downstream products can have EMC problems since the hot terminal isn't properly filtered to ground. In other cases protection mechanisms (like fuses) which are normally only present on the HOT line for many domestic products will be unsafe during a fault condition (the fuse will disable the device but not remove live power from the circuitry as intended.
I would highly recommend people do not use this product even though it may seem fine under normal conditions.

There's also an FCC test report for the MFISH E-TANK-240W showing the sample was received in October 2024, while Genki's Moonbase crowdfunding campaign didn't go live until December 2024.
That doesn't prove who originally designed the 240W version, or whether there was a shared OEM involved, but it does make the simple "MFish saw Moonbase and copied it afterward" explanation hard to square with the public timeline.
For context, I just found this through Google and checked the public Kickstarter/Indiegogo pages and FCC docs. I used GPT to help organize the timeline, but the dates themselves are from those public sources.
Community Reviews
MFish E-Tank is a compact desktop charging station that combines three AC outlets with four USB C ports, RGB lighting, and high wattage charging in one hub. The design is also described as very similar to Genki Moonbase, and the price is called much better than buying a comparable Ugreen Nexode 200W setup. The main concern is electrical safety, with repeated testing showing hot and neutral reversed on some units. That makes it a neat desk charger on paper, but the wiring issue is hard to ignore.
The station offers 3 AC outlets and 4 USB-C ports without any USB-A ports included.
The product's public timeline and FCC sample receipt dates make a simple "copied after crowdfunding" story harder to reconcile.
The outlet lighting behavior can be visually distinctive, with red socket lights and pulsing activity.
The charger is described as having UL safety certification and a PC94V-0 fire-rated enclosure with 1250W surge protection.
Hot and neutral appear reversed on multiple units when tested with outlet testers or multimeters.
Reversed hot and neutral wiring can defeat surge protection and fuses, leaving metal parts or connected devices electrically energized.
MFish support response directs Amazon-order customers to contact Amazon for exchange or refund instead of providing direct after-sales handling.
The promo code flow can be confusing because the code requires tapping the arrow in the promo box before continuing.

Whats weird with the reviews is not many photos of people using the USB-C ports... And plugging in their own wall-wart chargers instead.
When considering reviews is good to ask yourself : how often do you write a review? Is it only when something is very good? Or get bad? Or never? Chances are many people are like you.
