3.5 (6 reviews)
The Power Tank technology of pressurized ballpoint pens has been super well received by pen lovers all over the world that Uni has made newly designed pen bodies to host the technology!

The new “Smart” series of Power Tank pens come in 2 body designs. The regular series comes in shimmering polycarbonate barrels that have subtle patterns of colors. The High Grade series showcases a fine spiral design on the aluminum pen barrel.

The regular series uses standard Power Tank refills, while the High Grade series has its own metallic casing refills. Both series come in 6 body colors with 0.7 mm black ink refills. The High Grade series also has a silver body pen in 1.0 mm.

The Power Tank pen is worthy of being used either in the military or excursions to Antarctica. The pen writes in extreme conditions including wet surfaces, cool temperatures, and even upside down. Normal pens utilize gravity to create ink flow onto a paper. But the Power Tank utilizes internal compressed air pressure to push out ink onto the paper. Revolving air inside allows it to continually push ink out until the end. The pen can write in weightless conditions such as in space, on wet paper and subzero environments. The oil based pigment ink is high density and comes out smooth and dark on paper. You can write super fast without skipping or scratching the paper.

Wrote acceptably but the barrel fractured, rendering it dangerous to use. Very disappointing! I had high hopes for this pen. Save your money by buying the regular kind, or get a proper Fisher Space Pen.

I found the ink to be acceptable. I used this as my dedicated car-pen; in good temperatures it writes like a good ballpoint, and in sub-zero Canadian winters it writes like a thick, below-average ballpoint: that it still writes is impressive enough for me!

Unfortunately, the top of the barrel fractured, and while the pen is still intact, clicking the pen down or up you risk having the top pop off. I have stopped using it for fear of losing it forever.

Total usage: a few hundred lines in my car, and a *single day* of pocket carry, prematurely aborted because I noticed the barrel had already snapped.

Writes very smooth and consistent ink flow. Line thickness is more like a 0.5mm than a 0.7mm.

This is the same review that I wrote for the silver version.

The refill is excellent. The grip area is very slippery. Imagine the most slippery pen you have (for me it's a stainless Parker Jotter), and I guarantee this grip is 10 times worse. It's also somewhat fat, which compounds the problem.

I scuffed the grip with 50 grit sandpaper, I cut grooves in it, I sprayed Plasti-Dip on it. The final solution was to sand it down and put a Pilot G2 grip on it. It's not pretty now, but it's actually usable.

I went to all that work because the rest of the pen is so good. I consider this pen mostly useless without modification. I can't believe this pen made it to production--nobody at the company could have possibly thought the grip was acceptable.

Not impressed - I may have a bad pen because I have yet to experience the 'smooth' quality that others have described. The ink is not that dark and does not flow like some of the Zebra Surari pens.

Although not fancy, this pen must be the best ballpoint available. A very smooth line is produced, and the long-lasting cartridge is easily replaced by unscrewing the clip & button end of the pen. Barrel colors are nice, too. I own three and I have been very pleased with this Uni-ball product.
