• Safety First, Always:
  Equipped with multi-layer electrical protections (over/under voltage, RCD, surge, short-circuit, over-current) + IEC/UL/ENEC compliance & TUV/CE/FCC certification. Its flame-retardant PC+ABS housing and PCB board add an extra shield—so you power up without worry.
• Made for Every Region:
  Pick the plug that fits your space: Schuko, NEMA 5-15P, CEE 7, or NEMA 14-50P. Works with 230V/125V inputs (50/60Hz) — perfect for frequent travelers or multi-location offices.
• Customized to Your Routine:
  Need a longer cable? We’ve got customizable length options (starting at 5ft). Prefer plug-and-play simplicity? It’s ready to go the second you connect it. The RGB/LED indicator keeps you in the loop (no guessing if it’s charging!).
• Built to Last:
  Natural cooling design handles -20°C to 60°C temperatures (even at 2000M altitude) — and backed by a 2-year warranty. Whether it’s your laptop, workstation, or gear, HD-Plus keeps up.
