Buffs temporarily increase PL. Equipment raises it also. Your base PL only gets higher with your level though. I wouldn't worry about it since it doesn't really carry much weight in game when compared to skill and actual level.
Pay 0 attention to power level. It is meaningless.
Also for instance most fighters wear dex. Dex increases your power level by a very small amount, where as most SK's use CON which increases power level by a very large amount. Not only that but nameks have much higher standard LP than humans. A namek and Majins power level will always be higher than a Humans.
Also crit rate, attack speed and crit % gloves add 0 power level, where as focus gloves increases it. All these gloves have there uses.
Just try to ignore it. However if you really want to know. Buy CON gear, use ENERGY earrings (I warn you though, ENERGY is a terrible stat) Upgrade armour, and Gloves. Upgrading your sub weapon adds no power level.
Just worry about the stats on your gear and not about the power level they give.
CON, ENERGY, Defence and Attack increase your power level by the most Focus is also good.
first thing in the pl in game does not help much in my opinion, however, if you really want to exponentially increase your pl just that increases the characteristic CON or ENG as much as possible, but I do not recommend to do it on a fighter. fighter full with are not very decent
