4.3 (8 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.

I was already a fan of the Power Tank RT pens, so I was not surprised that I liked the Smart Series as well.

My biggest problem with the RT was that the clip always seemed to break after awhile. The Smart Series clip seems to be much better.

However, I like the rubber grip of the RT better than the plastic grip of the Smart Series, so I was pleased to discover that the 'click' mechanisms are interchangeable. I am now happily writing with my 'Frankenpen' that has an RT body and a Smart Series 'click' mechanism.

the ink that comes out of these are great! but there is a HUGE designer flaw. after about 1 month of use, the top cracks (point where the top screws into the pen body), and the top part can fly off by clicking the pen top sharply.

i bought about 7 of these, and all of them have done it!

I love these pens. I work at an Airport & I have to write outside in all temperatures. Any other pen I tried before would freeze, these ones don't. They write no matter what, never skipping ink while writing, no smudges. I have ordered extras just to have in all colors. Best pen ever & not too expensive.

Overall I like these pens.

The ink is good and it's a smooth writer. The body design is good and the grip is actually not that bad, although many complain about it.

The only down side is cold temperature performance. I bought one of these to keep in the car, as I did not want to be using a metal bodied Fisher space pen in the bitter cold.

The description says "...is worthy of being used either in the military or excursions to Antarctica.".

Don't think so. It was -28°C (-18°F) this morning and this pen would not write.
