4MYTU Tank Trunk 27-Inch Suitcase
A 27-inch top-opening check-in suitcase with 82L of space, USB charging and a handle that works as a mini workstation.
Is the 4MYTU Tank Trunk worth buying?
If you want one big check-in bag that handles a week or two away, the Trunk is a good one. The 82L capacity expands to 96L, the top-opening design keeps things simple, and the polycarbonate shell has protective feet so it can lie flat on its side. $485 is serious money for a suitcase, and the Trunk does weigh 10.83 lb empty. The Tank Carry-On also nests inside it for storage.
A large trunk-style suitcase
The Tank Trunk is the 27-inch check-in size in the Tank Series, with top opening rather than front access. The store lists it in several colors; this review uses Navy.
What makes it stand out
82L, expands to 96L
Interior size is 26.38 x 16.14 x 13.19 inches. Expansion adds about 4 cm of depth and about 14L of space. It is recommended on the page for 7 to 15 day trips.
Top-opening, no front pocket
The lid opens along the wide front of the case and gives access to one main compartment. There is no front pocket, which is the trade for the simpler design.
Cup holder, hook and USB charging
The same versatile handle and USB-A and USB-C ports as the Tank Carry-On. A power bank is not included.
Protective feet and PC shell
Four protective feet on the bottom and side keep the shell off the ground when it lies flat. The hard shell is polycarbonate, with a TSA lock and double-layer zipper.
