Pre-Built Coils by Medusa

Description

Building your own coils is great… until it isn’t. Pre-Built Coils by Medusa are made for experienced rebuildable users who want the performance of an RDA, RTA, or RDTA without spending half an hour wrapping wire and questioning every decision that led to this moment.

Each retail pack includes 2 matching pre-built coils (1 pair) plus MUJI organic cotton, so you can install, wick, verify the build, and get back to the part you actually care about.

L7 Stocked Variations

Not every manufacturer variation is necessarily stocked at L7. If you are looking for a specific build, ask us about availability.

Mesh Option

• Material: SS316L Stainless Steel
• Mesh: 300 Mesh

The mesh option is different from the wrapped Kanthal coil variations above and should be treated as a separate rebuildable material.

roduct Specifications

• Brand: Medusa
• Product Type: Pre-Built Rebuildable Coils
• Primary Coil Material: Kanthal
• Retail Pack Quantity: 2 matching coils / 1 pair
• Cotton Included: MUJI organic cotton
• Intended Use: Compatible RDAs, RTAs, RDTAs, and other rebuildable atomizers
• Resistance: Varies by coil style
• Mesh Material: SS316L for the 300 Mesh option

Compatibility

These coils are intended for rebuildable atomizers that accept user-installed wire coils, including compatible:

• RDAs
• RTAs
• RDTAs
• Other rebuildable platforms designed for user-installed coils

They are not drop-in replacement coils for standard sub-ohm tanks or pod systems.

Resistance Information

The listed resistance values are approximate per-coil ratings.

Actual resistance can vary based on:

• Coil leg length
• Installation method
• Build deck
• Connection quality
• Resistance reader or regulated device
• Single-coil versus multi-coil configuration

A dual-coil installation will generally produce a lower total resistance than the rating of one individual coil. Translation: two 0.20Ω coils do not magically become a relaxed 0.40Ω build because confidence was high.

Always verify the completed resistance before use.

Package Contents

Each individual retail pack contains:

• 2 matching pre-built coils
• MUJI organic cotton

Medusa’s updated wholesale packaging contains 5 individual retail packs, but each retail pack still contains 2 coils plus cotton.

Additional Product Information

These coils are intended for advanced rebuildable users who understand coil installation, resistance testing, Ohm’s law, and appropriate battery limits.

Some variations can produce very low-resistance builds, especially in dual-coil configurations. Always verify the completed build before firing and make sure the device and batteries are appropriate for the resulting resistance.

Rebuildables are the part of vaping where “close enough” becomes a considerably less entertaining phrase.
