iJoy XP100K Review: Extreme Modular Refillable Kit

August 28, 2026 By Robert_Patterson

The iJoy XP100K is one of the most extreme capacity systems currently available. It uses a dual-battery design (approximately 1500 mAh total), an 18 mL prefilled pod plus a 15 mL refill bottle (33 mL total), Norm and Boost modes, adjustable airflow, a large smart display, and dual mesh coils. Claimed output reaches 100,000 puffs in Normal mode.

After extended use, the combination of reusable power, high total liquid, and the ability to top up the pod sets it apart from both sealed disposables and simpler modular kits.

Key Specifications

Dual Battery System and Refill Design

The system pairs a main battery with a smaller pod battery. When the initial liquid is low you can refill from the included 15 mL bottle rather than immediately discarding the pod. Norm mode prioritizes longevity; Boost increases intensity. Adjustable airflow and the large display provide clear control and status information.

This is significantly more involved than a standard sealed disposable. It rewards users who want maximum longevity and are comfortable with a modular, refill-capable approach. Real-world total puffs depend heavily on mode and how the refill is used.

Who It’s Best For

Adult vapers who want extreme total capacity and are open to a modular system with a refill step. Best for users who prioritize longevity and lower long-term waste over pure simplicity.

Final Thoughts

The XP100K pushes capacity and modularity further than most current options. Large total liquid, dual-battery power, Norm/Boost modes, and a clear display make it a serious long-term platform for users who want maximum runtime. Available at Element Vape.
