The Uni Power Tank Smart Series 0.7 ($3.30) is another in the growing pressurized ballpoint market. The pressurized ink cartridges are designed to allow the pen to be used in severe weather, upside and in zero gravity though I’ve not had a lot of call to test the validity of these claims. The Fisher Space Pen is the original pressurized ballpoint. I don’t own one but my husband has one that he loves and uses regularly. The Fisher Space Pen is a small compact design with a standard Parker-style refill but the refill is pressurized to be used in extreme circumstances. I have a Rite in the Rain metal refillable pen that a reader sent to me as well.
The Uni Power Tank is a “disposable” pen so the entry to use is a little lower. Since its a standard plastic barrel pen, it doesn’t feel like a commitment to a pen lifestyle. I’ve previously reviewed the Tombow Airpress ballpoint pen which is a similar idea to the Uni Power Tank.
Compared to the Tombow Airpress which has a very wide, stout appearance, the Uni Power Tank Smart Series is a more streamlined pen design. The width for the Uni Power Tank Smart Series is similar to a Sharpie marker — wider than a hex pencil but not as chunky as the Airpress. The grip area is textured with some horizontal ridges but its not a particularly cushy bit.
In writing, there is no discernible difference between the Airpress and the Power Tank. If you like the funky Stormtrooper vibe of the Airpress, go for it. For me, though, I’m not a huge lover of ballpoints but sometimes I need one and sometimes I need a writing tool that is going to work after months of neglect. When I need that, I’m going to reach for the Power Tank.
I think of the Uni Power Tank Smart Series as being a very no-nonsense pen. It works in severe conditions, you can leave this pen in your car from Key West to Fargo without worrying about it exploding or leaking or ceasing to function. At less the $4, you can leave the Power Tank on the diner table on that epic road trip and not be heart broken over the loss.
