Engineer powers entire home using 500 discarded vapes in viral video

A viral video shows an engineer turning hundreds of discarded vape pens into a powerful home battery — and the result is hard to ignore. Salvaged lithium-ion cells from single-use devices were rebuilt into a 2.5 kWh energy bank that ran an entire house off-grid for hours, spotlighting the scale of e-waste and the hidden potential of recyclable components.

Chris Doel, an engineer who works at Jaguar Land Rover, pulled together the project after noticing friends and festival-goers routinely trashing used vapes. What started as a curiosity grew into a months-long effort to recover cells, test them, and assemble a functioning battery pack that demonstrates both practical reuse and a critique of disposable electronics.

From roadside trash to working battery: how the idea took off

Doel’s project began with a simple observation: disposable vape pens almost always contain rechargeable lithium-ion cells. Rather than accept these devices as truly single-use, he started collecting them — picking up discarded units at events and asking a local vape shop to donate returned items. The shop handed over thousands, because retailers still have to pay to recycle them and were glad to offload the stock.

He then developed a fast way to sort functioning cells from damaged ones. Using a mechanical pump to “vape” each device briefly, he could tell which batteries still held charge and which were likely compromised. Over roughly six months he opened thousands of pens and extracted hundreds of cells for reuse.

How the battery pack was engineered and assembled

Doel combined hands-on electrical work with 3D printing to make the pack practical and safe. Key steps included:

• Extracting individual lithium-ion cells from each discarded vape pen.
• Testing cells mechanically and electrically to filter out damaged units.
• Grouping cells into parallel banks, then wiring those banks in series to reach the desired voltage and capacity.
• 3D-printing an enclosure to hold the assembly and provide mechanical protection.
• Soldering a small fuse between each recovered cell to reduce the risk of short circuits and improve safety.

By wiring about 500 usable cells into the final configuration, he reached approximately 2.5 kilowatt-hours of storage. In a live trial he powered all household loads — lighting, appliances, and small kitchen devices — for an eight-hour period without any grid input.

Technical details and real-world performance

Instead of relying on a single large commercial battery, Doel’s design uses dozens of individual 18650-like cells salvaged from vape pens. The modular approach meant he could replace or isolate weak cells easily and build the pack to a specific capacity.

• Capacity: ~2.5 kWh from 500 reclaimed cells.
• Runtime: Demonstrated eight hours powering a typical home load during testing.
• Safety features: Individual fuses and careful cell testing to limit shorting and thermal issues.
• Packaging: Custom 3D-printed housing to secure each battery group and simplify wiring.

Doel also documented the whole process on YouTube, where the build video attracted millions of views and sparked conversations about electronic waste, DIY battery builds, and small-scale energy independence.

Environmental implications and the problem of single-use electronics

The project underlines a contradiction: many disposable vapes advertise convenience while containing rechargeable lithium-ion technology — the very chemistry promoted as an alternative to throwaway batteries. When these devices are discarded, valuable materials and energy-storage components are lost.

Doel argues that the market push toward cheap, disposable vapes contributes to unnecessary e-waste. Retailers told him they often pay to recycle returned devices, which is why one shop agreed to give him piles of returns rather than handle disposal themselves. In response to mounting concern, the UK moved to ban the sale and supply of single-use vapes in June, a policy shift that aims to reduce waste even if enforcement and implementation remain works in progress.

What he learned and where the project is headed

Having proven the concept, Doel is already thinking about next steps. He plans to integrate solar charging so the reclaimed battery bank can recharge during the day and run continuously or fill overnight when electricity is cheaper. He’s also exploring ways to scale safe testing and recovery so more discarded cells can be diverted from landfill.

• Scaling collection: partnerships with retailers and events to capture discarded devices.
• Safety standardization: better testing rigs and cell-matching practices for reclaimed packs.
• Renewable integration: combining the pack with a rooftop solar array and charge controller.

The project has resonated widely because it blends a practical, hands-on engineering challenge with a clear environmental message: a surprisingly large amount of useful battery material is getting thrown away every day. The build demonstrates that reclaimed cells can deliver meaningful, real-world power — enough to run a home for hours — when recovered and assembled carefully.

Community reaction and wider impact in media

The online response has been strong. Viewers praised the ingenuity and raised questions about liability, safety, and how best to handle electronic waste at scale. The video documenting the build has amassed millions of views, sparking discussions across social platforms about refillable vs. disposable vaping products and the lifecycle of consumer batteries.

Many commenters urged caution and noted that DIY battery packs require knowledge and respect for electrical safety. Others saw the project as a blueprint for reducing e-waste through local recovery programs and maker-community initiatives.
