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.

Lab in China. Looks standard though. I am now skeptical of claims that the hot wire is reversed. May be someone who has electrical experience can test it?

Last time I bought a high-wattage power supply for a 5G modem I had to look very carefully to find a genuine product that was still listed directly on UL's site. There were tons of fakes that claimed to be listed but had fake registration marks on the power supplies.
"Hello,
Thank you for sharing the details! It appears your order was placed through Amazon, so we are unable to directly handle after-sales matters.
Please contact Amazon customer service through the app—they will assist you with the exchange or refund process.
I will also report it to the Amazon department, and they should contact you.
Best regards,

Some comment on the wiring would have been expected. Don't get the impression they cared.

Did you also notice that the plug seems wired in reverse? The cable comes off the top of the plug rather than the bottom once plugged in. Is that just me or is it somehow not wired in the usual way for US standards?
