@markoa7

As an accomplished electronic hardware and firmware engineer, I have built a career around transforming ideas into reality through meticulous design and development. I am no stranger to delicately handling electronics; I carry a fine-tip soldering iron, ESD mat, and all the necessary tools for this project. What sets me apart is my proven track record in developing reliable circuits within tight spaces, such as with the power supply circuits and multi-layer designs that your e-cigarettes require. My years of experience programming microcontrollers and implementing wireless technologies will be invaluable when it comes to verifying charging and firing on each repaired unit. I will be able to provide those short records you desire documenting the charge test for each unit, ensuring its voltage levels after full charge and quick activation meet your acceptance criteria. At the core of my work is a commitment to delivering cost-effective, high-quality solutions without sacrificing deadlines; this aligns perfectly with your needs. With me on board, you can rest assured that every joint will be neat and every connection reliable, with zero cosmetic damage. Furthermore, I'll be able to pack these devices safely back for return as per your preference ensuring their security in transit. Thank you for considering me for this project.

⭐⭐⭐⭐⭐ I’ve handled similar micro-rework jobs on compact consumer electronics, so I’m comfortable working in tight housings with fragile pads and Li-ion cells. Approach: • Controlled low-temp desoldering with flux to avoid pad lift • Install new cells with clean, strain-relieved joints (heat control + insulation) • Inspect polarity + protection circuit integrity on each unit • Careful reassembly so shells snap back without marks Testing per unit: • Full charge verification (record final voltage) • Activation test (confirm firing + stable output) • Quick visual + electrical check before packing Handling & protection: • ESD-safe workstation • Heat shielding around plastic areas • Cell insulation (Kapton/heat-shrink as needed) Quick question: are these 1S protected cells, or do the devices handle protection internally?

Hi, I can handle the battery replacement for your cigalike e-cigarettes with clean, precise work. I’m experienced with micro-soldering on small PCBs and tight enclosures, so desoldering the old cells and installing the new lithium-ion batteries will be done carefully without damaging pads or housings. I’ll ensure neat joints, proper insulation, and full reassembly so each unit closes as original. After completion, I’ll test every device (charge + activation) and provide a simple report with voltage readings. Turnaround will be quick once received, and I can guide you on safe packaging for shipping both ways. Thank you.

Hi, I can handle this rework safely and efficiently. I have hands-on experience in designing and repairing electronic cigarette hardware, including compact battery-powered PCB layouts, which makes me very familiar with the tight mechanical constraints and delicate soldering involved in cigalike devices. -For your 15 units, I will: *Cleanly remove the old batteries without damaging pads or plastic housing *Install the new lithium-ion cells with precise, reliable soldering *Ensure proper insulation and mechanical fit inside the original shell *Reassemble each unit so it snaps closed as intended *Test charging and activation for every device I use fine-tip soldering tools, ESD-safe handling, and proper flux/heat-shrink techniques to ensure both electrical reliability and clean cosmetic results. After completion, I will provide a simple test log for each unit (charging voltage and activation check) as requested. I’m ready to start as soon as the devices are shipped. Best regards, Thank you.

Hello, With a background in Electrical Engineering and Project Management, I'm never a stranger to precision, neatness, and reliability. I understand just how crucial it is for you to have your fifteen e-cigarettes repaired flawlessly. They say a true professional does not rest until each job is completed to the client's satisfaction, and that's what I bring to the table. Throughout my career, I've honed my soldering skills, which make me capable of working on very small PCB pads with steady hands. My experience in project management not only taught me the importance of delivering within deadlines but also instilled the passion for comprehensive work. In line with your request for a record of charge testing for each unit as acceptance criteria, you can trust that each device will be thoroughly checked and verified before its safe return. To demonstrate my ability to create value - whether in Architectural permitting or in this soldering task - I would happily provide a third-party review of any the lithium-ion battery replacement process for one unit before starting on all fifteen simultaneously. This way, you can assess my proficiency hands-on while safeguarding your project from any complications.. We can then establish a reasonable turnaround-time and discuss how you prefer the reassembled devices packed for their safe return. The ball is now in your court! Thanks!

Hi, I can handle the battery replacements for your 15 first-generation cigalike e-cigarettes with careful micro-soldering, clean reassembly, and documented testing before return. I’m comfortable working around small PCB pads, thin leads, tight plastic housings, and lithium-ion safety requirements. - Desolder the depleted cells cleanly - Install the supplied replacement lithium-ion batteries with neat, reliable joints - Add heat-shrink/insulation where needed without affecting fit - Reassemble each shell with zero cosmetic damage as the priority - Record full-charge voltage and quick activation results for all 15 units Please pack each device so the shells cannot rub or flex in transit, ideally in individual sleeves or bubble wrap. I’ll provide tools, ESD-safe handling, soldering materials, and a clear test log upon completion. clientQuestion Best regards, Thomas
