Last updated: 29 October 2026. Comparison by Cloud Express, based on the product information we publish for each device. We sell all three.
ASDF makes three refillable open pod devices: the Offgrid Reload, the Offgrid Engage and the Core. All three let you fill your own e-liquid, but they differ in tank size, coil and design. Here’s how they compare.
The short answer
- Biggest tank, fewest refills: Offgrid Reload (10ml).
- Custom look and adjustable airflow: Offgrid Engage (5ml, switchable panels).
- Slim stick with a choice of coil: Core (3ml, 0.4Ω or 0.6Ω).

Offgrid Reload: the big-tank option
The Offgrid Reload Starter Kit comes with the device and a 10ml refillable cartridge with a dual mesh 1.0Ω coil and adjustable airflow. It works with nicotine salt and freebase e-liquids. Unplug 15ml is made for it, and one bottle fills the cartridge with some to spare.
Offgrid Engage: the customisable option
The Offgrid Engage is built for people who like to make their gear their own. Swap its panels to change the look, and adjust the airflow to tune flavour and vapour. It uses the 5ml dual mesh Engage cartridge.
Core: the slim option
The ASDF Core is a streamlined stick for people who want the essentials done well. Its 3ml cartridge comes in two resistances: 0.4Ω for direct-to-lung vaping with more vapour, and 0.6Ω for mouth-to-lung or restricted direct-to-lung, which suits nic salt. Not sure which? See our coil resistance guide.
FAQs
Are the cartridges interchangeable between the three?
No. Each device uses its own cartridge: the Reload cartridge, the Engage cartridge or the Core cartridge.
Which one is best for freebase?
The Core with the 0.4Ω cartridge is built for direct-to-lung freebase vaping. The Reload and Engage also take freebase.
Which one is best for saltnic and a tight draw?
The Reload, with its 1.0Ω coil, or the Core with the 0.6Ω cartridge. See saltnic vs freebase vs HTPC.
