充电器外贸客诉处理与售后话术

不识别快充 = 协议握手失败。90% 是**协议不匹配**（如客户手机需 PPS，我方只支持 PD 3.0），10% 是产品故障。要先诊断责任。

Hi {Name}, "Fast charge not activating" is our #1 troubleshoot case — happens across the industry. Usually protocol mismatch, sometimes cable, occasionally product. Let me diagnose fast. **What I need from your customer or your inspection**: 1. **Which device is complaining** (exact model + iOS/Android version): - iPhone 15 Pro (expects PD 20W) - Samsung S24 Ultra (expects PPS 45W — this is where many chargers fail) - MacBook Pro M3 (expects PD 65–96W) - Etc. 2. **What cable are they using**? - Our included E-Marker C-to-C? (should be fine) - A random C-to-C cable? (may not have E-Marker, limits to 60W) - Apple's Lightning-to-C cable? (only works for iPhone 14 and earlier) - USB-A to Lightning cable? (never works at fast charge speed) 3. **What's the observed behavior**: - Charges but very slowly (0–50% in 2+ hours) → protocol mismatch, fell back to 5V/2A - Charges normally (0–50% in 30–45 min) → actually working, customer misunderstanding - Doesn't charge at all → cable or port issue - Charges then disconnects randomly → E-Marker issue or overheating 4. **Video of charging status screen** (Samsung shows "Super Fast Charging", iPhone shows lightning bolt, Mac shows charging port context) **Common resolutions**: **Case A — PPS not supported on my product but customer's Samsung needs it (40% of cases)**: - Customer's device falls back to slower QC 3.0 or PD 3.0 (still 18W, but not the 45W expected) - Fix: verify your product spec sheet claims PPS. If not, this is a mis-purchase, not a defect. If yes and it's not delivering, it's my hardware issue. **Case B — Cable issue (30%)**: - Non-E-Marker cable limits to 60W - Fix: replace cable, verify same charger works properly with E-Marker cable **Case C — Product defect (20%)**: - Actual protocol negotiation failure due to firmware bug or PCB defect - Fix: replace unit, ship diagnosis to our engineering **Case D — Customer expectation issue (10%)**: - Customer expected 45W on their iPhone 15 Pro (which is capped at 20W by Apple regardless of charger) - Fix: education, no defect **Regardless of cause**: - Replace failed unit within 24 hours, air freight my cost - If Case C (real defect) in >5% of shipment, full batch RMA - Update your Amazon listing FAQs with protocol clarity to reduce Case A/D returns Send me the diagnostic info + 24 hours later I have a diagnosis + action plan. Best, {Your Name}

Hi {Name}, "Runs hot" complaints on GaN chargers — real risk, take seriously. Let me diagnose because there's a difference between "warm and safe" vs. "unsafe hot": **Physical reality**: - GaN chargers WILL feel warm at full load — this is normal - 40W GaN at max load: 40–48°C surface (warm but comfortable to touch) - 65W GaN at max load: 45–52°C surface (perceptibly hot but within UL 62368-1 accessible surface limit of 55°C for plastics) - >55°C = safety issue, product recall territory **What I need from customer**: 1. **Actual temperature measurement** (IR thermometer or thermal camera): what temp, on what surface (metal contact, plastic shell, prongs)? 2. **Which device** was charging + **what wattage** (visible in device charging screen) 3. **How long** was it charging when temp was measured 4. **Ambient temp** in room (30°C tropical vs 20°C AC-cooled matters) 5. **Ventilation** — was charger in enclosed space (behind couch, inside bag) or open? **Categorization**: **Category A — Normal warm operation (60% of complaints)**: - 40–52°C at max load, ambient 25°C, open ventilation - This is spec-normal, not a defect - Fix: customer education, no product change **Category B — High but within-spec (20%)**: - 52–55°C at max load, hot ambient (30°C+) or poor ventilation - Within UL 62368-1 limit but perceived as "unsafe" by consumer - Fix: replacement not needed but update listing photos to show open ventilation recommendation; consider aluminum-accent version for premium heat dissipation **Category C — Genuine safety issue (10%)**: - >55°C, or shell warping, or discoloration - Product defect, full RMA + potentially recall - Fix: batch inspection, 8D root cause, potential recall action **Category D — Actual fire/melt (rare, <1% but critical)**: - See next section (safety incident handling) **What I commit right now**: - Categories A + B: replacement not required but I'll credit 1 unit per complaint for goodwill + suggest listing tweaks - Category C: full batch RMA if >0.5% of shipment shows same pattern; free unit replacement + air ship - Category D: immediate escalation, see safety incident SOP Send me the diagnostic info per Category, I'll act. Best, {Your Name}

**最高危场景**。这可能触发亚马逊召回、CPSC 调查、产品责任诉讼。销售话术必须**极度克制**：不承认责任、不否认责任、不猜测原因、立即启动内部升级。

Hi {Name}, Received your urgent notice. I want to be direct: reports of smoke, fire, or electrical shock are treated with the highest severity on our side. I take this personally and will personally coordinate the response. **Immediate action items in the next 4 hours** (I've already initiated these on my side, no waiting for your instructions): 1. **Safety hold**: batch you received is placed on internal hold; no further shipment from this batch to any customer globally until root cause established 2. **Retention samples**: our engineering + QA team pulling all retained units from your batch for immediate analysis 3. **Escalation to our safety director + product liability insurer**: notified within the next hour 4. **Certification body notification**: UL, FCC, our CB scheme lab will be notified within 24 hours per compliance obligation **What I need from you (please prioritize, understand this may be difficult)**: 1. **Preserve the incident unit exactly as-is** — do NOT clean, disassemble, or discard. Photograph in current condition from multiple angles. 2. **Photos of the incident**: unit, immediate surroundings, any damaged property or affected person 3. **Batch code** from carton or unit label 4. **Where was it purchased** — verify it's authentic (not counterfeit resale from a third party) 5. **What device was connected**: was the charger being used or standalone plugged in 6. **Was anyone injured**: this changes escalation path 7. **Property damage assessment**: extent of any collateral damage 8. **Customer / end user contact info**: our insurance may need to contact directly (with their permission) **What I will NOT do** (and I need you not to either): - **Don't offer immediate cause explanation** ("must be a manufacturing defect" or "must be customer misuse") — until we've done proper analysis, any speculation is premature and can create legal exposure for both of us - **Don't destroy or replace the incident unit** — it's evidence, forensic value degrades if handled - **Don't respond publicly** on social media / Amazon reviews until we have proper facts + coordinated messaging **What I WILL do**: - **Coordinate with our product liability insurer** ({insurer name}) on incident investigation — they handle policyholder notification, on-scene inspection if needed, and coverage for medical/property claims - **Independent forensic analysis** at accredited failure analysis lab within 5 business days — root cause report by day 21 - **CPSC coordination** if the incident triggers US CPSC voluntary reporting threshold — our compliance director handles - **Amazon incident report** if you're on Amazon — coordinate together to file per Amazon's product safety process, avoiding an uncoordinated seller-only report that can escalate to your account - **Financial support**: legitimate medical costs, property damage, product replacement, listing removal costs — funded through our product liability coverage. This is not a "goodwill gesture", this is legitimate coverage. **Timeline**: - Hour 1–4: Initial escalation (in progress on my side now) - Day 1: Incident documentation + shipment of retention units to failure analysis lab - Day 3: Lab preliminary findings - Day 7: Batch-level testing analysis complete - Day 14: Root cause identified with certainty - Day 21: Full 8D report + corrective/preventive action + recall decision (if warranted) **I'll call you within 30 minutes of you receiving this** to walk through in person and answer questions. Please share a good time / phone number. If English isn't your first language and you'd prefer another, we have Mandarin, Spanish, Portuguese, Russian, Arabic on our side. This is my full attention until resolved. Talk in 30 min. {Your Name} Senior Sales Director | {Company} Direct: {mobile} | Available 24/7 until resolved
