By Bat Digest | Last Updated November 17, 2022

On the whole, hitters immediately noticed the size of the barrel. It is, at least in the 33-inch BBCOR realm, the largest barreled BBCOR bat on the market. As well, it runs one of the lightest swinging bats on the market. In essence, if you want the largest barrel with the lightest swing then you just found your bat.

Comparable Bats

The single piece composite bat realm for 2019 is thin. The only comparable bat for this given year is Dirty South’s Kamo. That, too, is a single piece composite. But, notably, the Kamo swings heavier than the Power Carbon. Expect an 8 to 9% increase in swing weight from one bat to another. The Power Carbon does have a bigger barrel profile but not by much. Both barrels are monsters.


The Mizuno Power Carbon for BBCOR and USSSA (not to be confused with the Power Carbon in fastpitch) is a single piece composite bat. This means Mizuno essentially produces the entire bat in a single process for synthetic material best described to the layman as plastic. Mizuno’s composite is referred to as Black Onyx Carbon. Black Onyx is, for all intents and purposes, a marketing term for their type of composite used in the bat.

Another unique feature on the 2019 Mizuno Power Carbon is the grip. They use a unique design in the grip to produce some better comfort and feel. Our players liked it and commented on it.

Overall Ratings

The overall rating uses seven different weighted metrics to determine our overall score. Half of total rating comes from the player and our exit speed tests (Player Rating: 25%, Performance: 25%).The other categories are Relevance (20%), Demand (10%), Durability (10%), Resell Score (5%), and Tech Specs (5%).

*: When a bat is denoted by a star (*) it is a preliminary rating. Expect it to be updated as we learn more about the bat and gather more data.

(PlaRa) Player Rating: We measure player rating from user reviews. Those users include our own hitters that we test at the lab as well as reviews we find online.

(ExVe) Performance: Performance measures the exit speeds and distances we capture in our hitting lab with HitTrax using these bats.

(Relv) Relevance: We measure the number of sizes and the MOI of the bat. Bats with a wider range of options get a better score.

(Dmnd) Demand: Demand is measured by consumer sentiment and the buzz around the bat.

(Drb) Durability: A bat’s durability is measured by user reviews as well as feedback from manufacturers.

(ReSl) Resell Score: Based on the price the bats go for used. Higher prices mean greater user demand which means, generally, a better bat. A resell value closer to its original price means a higher score.

(Tech) Tech Specs: We rate the bat on its technological advancements from previous years and compared to the industry at large. This is our chance to reward companies who are trying to innovate.
MOI or Mass Moment of Inertia is a measurement of bat swing weight. This quantifies how difficult it is to swing a bat. The industry often refers to this as things like End Load or Balanced but those words have been overused to the point of meaninglessness. We measure the actual swing weights of each bat we test using the industry-standard pendulum period, balance point, and scale weight. You can read more about that here.
The price is the original MSRP price of the bat.
The types of bats are single-piece alloy (SPA), two-piece composite (TPC), single-piece composite (SPC), hybrid (Hyb.), and wood (Wood). Hybrid bats are made of composite handles and alloy barrles.
