Empty AIO Hardware Comparison: Briar vs Nook vs Lumen vs Wisp
Start with the reservoir, body shape, and output you need — not with price. All four models are empty rechargeable AIO hardware for brands that fill and cap in-house.
| Briar | Nook | Lumen | Wisp | |
|---|---|---|---|---|
| Reservoir | 1.0mL glass | 2.0mL | Two independent 1.0mL chambers | 1.0mL |
| Body | Glass-chamber AIO | Compact 2mL | Dual-chamber AIO | 10mm slim |
| Output | Three modes | Fixed 2.8V | Left / right / both | Fixed 1.8V |
| Charging | USB-C | USB-C | USB-C | USB-C |
| Best for | Seeing the oil and adjusting output | Larger capacity, fewer settings | Comparing two oils | Slim builds and low-voltage oils |
| Sample / reorder | 5 / 50 | 5 / 50 | 5 / 50 | 5 / 50 |
| Wholesale / custom | 2,000+ | 2,000+ | 2,000+ | 2,000+ |
How to choose
- Glass vs plastic: Briar lets you see the reservoir; Nook and Wisp prioritize a compact body.
- One chamber vs two: Lumen keeps two oils separate until the selector chooses left, right, or both.
- Adjustable vs fixed: Briar offers three output modes; Nook (2.8V) and Wisp (1.8V) are fixed.
Questions to ask any supplier
- What is the MOQ for this exact model and packaging combination?
- Does the sample include packaging, and what changes at 50 and 2,000+?
- Which filling or capping failure modes have they actually seen?
- Do they support dropship or affiliate arrangements?
- Which documents can they confirm before an order?
Use the procurement checklist to record answers, and the quote comparison worksheet to compare landed costs.
