myVolts 90W AC Adapter Square Tip 11×5.0mm

90 W Square-Tip Adapter for ThinkPad & IdeaPad

This 90 W AC adapter delivers 20 V at 4.5 A through an 11 × 5.0 mm square connector. It fits a wide range of Lenovo ThinkPad Yoga, X-series, E-series, T-series, L-series, P-series, Helix, Chromebook and IdeaPad models listed in the compatibility data. The unit accepts 100–240 V input at 50/60 Hz for worldwide use.

Thermals, Noise and Power Draw

As an external power supply it has no internal fan, so operation is silent. The adapter converts mains power at up to 90 W output with built-in over-voltage, over-load, over-current and short-circuit protection. It is CE, FCC and RoHS certified for safe, efficient charging in normal use.

Replaces Original Lenovo 90 W, 65 W or 45 W Units

This adapter directly replaces Lenovo part numbers such as ADLX90NCC3A, ADLX90NDC3A, ADLX90NLC3A, PA-1900-72 and the 45N0xxx series. It also covers 65 W and 45 W models with the same 11 × 5.0 mm tip, so one unit can serve multiple ThinkPad and IdeaPad generations. The upgrade is worthwhile when the original charger is lost, damaged or when a single spare must cover several compatible laptops.
