Hi {Name}, Charger sample delivered — DHL 998877, ETA {date}. What's in the box: - 3 pcs of your 65W dual-C GaN sample (SN 001, 002, 003) - 1 USB-C to USB-C cable (100W rated, E-Marker chip) - Test report from our EMC lab (FCC + CE pre-scan) - This checklist **Please test the following before signing off** — these are the exact scenarios your Amazon customers will hit. If any fail, tell me and I re-tune before production. **A. Device compatibility (10 devices minimum)**: | Device | Expected max power | What to verify | |---|---|---| | MacBook Pro 14" M3 (or similar) | 65–67W | Charging speed matches Apple 67W charger within 5% | | MacBook Air M3 | 30W (default) or 65W (fast mode) | Fast mode when using PD-supported cable | | iPad Pro M4 | 30W | Full-speed PD | | iPhone 15 Pro | 20W | PD Fast Charge kicks in (0–50% in ~30 min) | | Samsung Galaxy S24 Ultra | 45W | **PPS active** — this is where fake PPS units fail | | Google Pixel 8 Pro | 27W | PPS active | | AirPods Pro (case) | 5W | Trickle charge, no over-heat | | Steam Deck | 45W | Handheld gaming market | | Nintendo Switch OLED | 15W | Full-speed dock-off charging | | Older Android (QC 3.0) | 18W | Backwards compatibility | **B. Multi-device simultaneous test**: - Plug MacBook Pro + iPhone simultaneously → should intelligent-split to 45W + 18W (or similar per your unit's algorithm) - Plug 2× MacBook Pro → should distribute 45W + 20W (limited by total 65W budget) - Both cases: verify no device gets slower charging than a solo 20W charger would provide **C. Thermal test** (critical, this is where cheap GaN fails): - Charge MacBook Pro at max 65W solo for 45 minutes - Measure shell surface temp with IR thermometer at 45 min mark - **Pass threshold**: <52°C at hottest spot (UL 62368-1 accessible surface limit) - **Comparison**: Anker 65W Nano II typically hits 48–51°C at same test **D. Cable compatibility**: - Use your own USB-C to USB-C cable (E-Marker chipped for 100W+): should hit full speed - Use a non-E-Marker cable: should limit to 60W (safety fallback) — verify our unit respects this - Try a known-bad cable (broken E-Marker): should either fail gracefully or limit to 20W, NOT hard-reset device **E. Real-world durability** (do this over 5 days if you can): - Plug/unplug 200 times (approximates 2 years of use) - Charge overnight while sleeping 5 nights (thermal cycling) - Try in high-humidity environment (bathroom shower steam) — should not corrode contacts **F. Aesthetic + build**: - Feel weight: should feel dense (real GaN + copper heatsink = heavier than expected for size). Featherweight = suspicious. - Shell: check for gaps, uneven color, mold flash - Prongs: should feel secure when folded/unfolded, no wobble - Print quality: FCC ID + model number etched or printed clearly **What "pass" looks like**: all 10 device targets hit within 5% of expected wattage; PPS confirmed on Samsung; thermal <52°C; cable behavior correct. If any test fails, send me: - Device tested + failure symptom - Photo or video if visual - Ambient temperature during thermal test I'll adjust PCB firmware or physical build and re-sample in 8 days. Best, {Your Name}

Hi {Name}, Full custom shell design — exciting. Here's the honest tooling roadmap so you plan cost + time correctly: **What "full custom shell" involves**: 1. **Industrial design (ID)**: your designer or ours delivers 2D/3D concept 2. **Design for Manufacturing (DFM)** review: we identify anything that can't mold cleanly, has sink marks risk, or drives cost unnecessarily 3. **PCB layout adjustment**: to fit inside your custom shell, we redesign PCB routing (2–4 weeks) 4. **Mold design**: 2D drawing (1 week) → your approval → 3D CAD → mold fabrication 5. **Mold fabrication**: P20 steel, 2–3 cavities typical. 4–5 weeks. 6. **T0 trial**: first shots from mold, we assemble 10 pcs, ship you 3 for evaluation (parting lines, gate marks, fit, feel) 7. **T1, T2 iterations**: minor mold tweaks based on T0 feedback (1 week each) 8. **Final approval + production start** **Timing**: - ID + DFM + PCB adjust: 3 weeks - Mold fabrication: 5 weeks - T0-T2 iterations: 3 weeks (2 revisions typical) - Production sample + your final approval: 1 week - Mass production: 3–4 weeks depending on volume - **Total from PO to first shipment: ~14–16 weeks** **Costs**: - ID (if we do it): $2,800–5,500 depending on complexity - DFM + PCB adjust: $1,800 - Mold (P20 steel, 2-cavity, medium complexity 65W GaN size): $3,800 - **Total tooling investment**: ~$6,500–11,000 one-time - Amortization: at 5K units, adds $1.30–2.20/unit; at 20K, adds $0.33–0.55/unit **Mold ownership**: - You paid = you own. We provide mold drawings + specs - We store free of charge as long as you order 500+ pcs/year - If you switch factory (rare but happens), we ship the mold to your new factory at your freight cost. No hostage. **What to avoid**: - Trying to skip DFM: leads to mold trial fails, adds 3 weeks + $1,500 in rework - Very thin walls (<1.2mm): higher rejection rate in molding - Sharp internal corners: sink marks, we recommend fillets - Textures Anker uses (matte fine-grain): looks premium but adds $700 to mold cost + 5% yield loss initially Do you have concept sketches or references? Send them and I'll do a free DFM review + confirmed quote in 5 business days. Best, {Your Name}
