🔥🔥 Smallest 100W Global Travel Adapter! Full Review + GaN Teardown (106W Real Test!)
🌍 Full review + teardown of the Smallest 100W Global Travel Adapter (ARSMEL)We test, stress, and tear it down to show you exactly what’s inside and whether it’s worth backing. ⚡🛠️
⭐ Quick TL;DR
Weight: 210 g ⚖️
Claimed/measured max: 100 W (measured 106 W on single C1 port) ⚡
Combined USB output: ~73 W (combined ports) 🔋
Ports: 3× USB-C + 2× USB-A (one C on main board = C1) + universal AC socket 🔌+ US Socket + 3 Plugs (EU, US, UK)
Simultaneous devices: Up to 7 devices (5 USB + 2 AC) 🔁
Protocols detected: PD 3.0, PPS, QC 4+, AFC (and other legacy protocols) 🔄
Voltage detection: Works across 100–240 V and claims support for 200+ countries 🌐
Thermals: Body 67–68 °C, USB ports up to 71 °C after 1 hour at full load — these are measured temps during testing. 🌡️
🔧 Teardown & internals (what we found)
Sliding plug mechanism & mechanical socket assembly — solid engineering but tight tolerances for some plug types. 🔩
AC detection board on the top of the bridge-rectifier board for AC sensing. 🔁
Main board: GaN power stage, large heat plate, SM transformer. 🧯
USB daughterboard: 2× C + 2× A. C1 is on the main board (highest wattage). 🔌
Safety & isolation: Y1 class capacitor, optocoupler isolation. 🛡️
Key ICs identified: GaN ICs P5145H OB2739F, PD controller IP2723T 🔎
Thermal management: metal heat plate soldered directly over the main GaN IC — still gets warm under sustained heavy load. 🔥
⚠️ Safety & practical notes
Thermal: Temperature hits ~67–71 °C under 1 hour of sustained full-load testing (100 W).
Use in well-ventilated places; avoid covering the adapter while charging high loads. 🌬️
Indian plug fit: EU plug is not fully compatible (loose fit). It still works, but treat with caution — We recommend a local converter or checking the fit before repeated high-current use. ⚠️
Cables: Always use certified cables rated for 100W+ for heavy loads. 🧵🔌
🔍 Who this is for
Travellers who want a single compact 100W hub that replaces multiple chargers ✈️
Power users who need single-port high wattage for laptops and fast-charging phones 💻📱
✅ Pros / Cons
Pros
Compact for a 100W GaN adapter 📏
Supports many fast-charge protocols ⚡
Can power 7 devices at once 🔁
Well-designed internals & safety components 🛡️
Cons
Gets hot under sustained full load (monitor usage) 🔥
Indian plug fit is not ideal (works but not snug) ⚠️
Combined wattage (Voltage) drops when multiple devices draw power ➗
Verdict: Compact, powerful, well-engineered internals — recommended for travellers and power users. ✅
