Larger amounts of energy can be generated by increasing the momentum of turning the Vortex Lever and rotation speed of the Vortex Charge. This gives the Nitro Dynamo ( ニトロダイナモ, Nitoro Dainamo) inside the Vortex Charge the momentum it needs to generate power for transformation and finishers.

The user then turns the Vortex Lever ( ボルテックレバー, Borutekku Rebā), a crank that generates power to the Vortex Charge ( ボルテックチャージャー, Borutekku Chāji) energy core generator unit by turning the lever. Kamen Rider Build transforms by inserting two Fullbottles into the Build Driver's Building Modules ( ビルディングモジュール, Birudingu Mojūru) and plugging them into the Twin Fullbottle Slots ( ツインフルボトルスロット, Tsuin Furubotoru Surotto). This is due to their Hazard Level increasing/decreasing depending on emotions. The stronger the emotions, the stronger the Rider's attacks will be.

L&P Amplifier ( L&Pアンプリファー, L&P Anpurifā): A converter installed inside the Driver that converts emotions into energy.It reads Hazard Levels, and will prevent transformation to anyone lower that a Hazard Level 3. Qualifizer ( クオリファイザー, Kuorifaizā): A biometric scanning device located in the black section at the rear of the Adjust Bind.When the Driver is not in use, it is stored inside the Driver. Adjust Bind ( アジャストバインド, Ajasuto Baindo): The yellow strap used to fix the Build Driver upon the waist.

It is so strong that it can withstand Smash attacks. It utilises high-strength material with heat and impact resistance, allowing it to protect internal mechanisms.
