The Sigelei Mini Book Mod replaced the Sigelei Mini late last year; transitioning from the old, boring square-shaped body style and making way for a more stylish and ergonomic design.

The Sigelei Mini Book offers up to 40W of output with temperature control; supporting nickel (Ni200) wire coils down to 0.05 ohms.

Available in several attractive colors, it's powered by a single 18650 battery and includes an easy-to-use magnetic battery cover, OLED screen, spring-loaded 510 and a variety of built-in safety features.

The Sigelei Mini Book Box Mod is a compact device with a sleek and stylish look; ideal for just about anyone with low to mid-range power needs.

Originally retailing for over $50, it's a great little device with lots of nice features – and prices have recently been slashed. You can now get one at many online stores for less than $20!

Though these are nowhere near as cutting edge as newer units, and they pack a small amount of power compared to Sigelei's Fuchai 213 Plus, which has 223W of power, they are pretty great value for money.
