The charger fails to fast-charge a laptop independently, directly contradicting the core '26 minutes faster' marketing claim.

“Recently, I bought the 737 120W charger to enable dual charging, but unfortunately, it fails to fast-charge the laptop by itself.”

vs Marketing: Marketing claims PowerIQ 4.0 ensures 'Charge Up to 26 Minutes Faster' with automatic power adjustment, but this owner experienced zero fast-charging on a single connected laptop.

The charger struggles to correctly distribute power when devices with varying wattage requirements are connected simultaneously, and raises voltage concerns for international use.

“It seems to struggle, particularly when charging devices with varying power requirements, such as Apple Watches alongside larger devices. For instance, it fails to charge [certain combinations].”

vs Marketing: Marketing claims Dynamic Power Distribution 'detects the power needs of connected devices and adjusts power automatically,' but 2 users report failures when mixing device types and voltage incompatibilities for international travel.

Some units stopped working prematurely, and customer service was reported as unresponsive with delivery delays and shipping errors.

“A few consumers noted that certain chargers stopped working prematurely or failed to arrive entirely. Reviewers additionally mentioned difficulties reaching customer service representatives.”

vs Marketing: Marketing positions the 737 as a 'high-performance charger,' but Trustpilot reports indicate premature failures and poor post-purchase support undermine that reliability claim.

Actual output power has been measured at 12% below the advertised specification, and concerns exist that sustained high-wattage charging degrades battery longevity.

“Output power 12% lower than advertised specification.”

vs Marketing: Marketing states 'up to 120W' output, but measured real-world output falls short by 12%, and users note that frequent 140W charging may be unhealthy for battery longevity — a trade-off not disclosed in marketing.

The charger does not support proprietary fast-charge protocols like OnePlus Dash Charge, limiting fast-charging benefits to compatible devices only.

“So unfortunately there is no way to dash charge your Oneplus with an Anker product as it isn't a supported protocol.”

vs Marketing: Marketing broadly claims faster charging for connected devices, but protocol incompatibility means users with OnePlus or similar proprietary-protocol devices will not experience the advertised speed benefits.
