I initially bough the 200W Anker charger which performed well. Except, it kept generating a "Weak charger state" warning message on my 5 year-old Lenovo laptop which normally charges at 70-80W, indicating some incompatibility with the newer charging standards. Upon measuring the 200W charger, it delivered the required power output of 70-80W despite of the warning, charging the laptop well. However the ongoing (and misleading) warning message quickly became a nuisance, so with the Black Friday deals I decided to order the 250W charger. I am please to report, that with that the annoying error message was gone.
Quick update on the 250W Anker charger after a few days of use:
CUSTOM CHARGING MODE: current firmware (as of Nov 2024) is 1.2.3.2. This allows custom charging profiles where you can set for every channel the desired output power with a slider. This allowed me to set 100-70-80-0 watts for the 4 USB C ports, allowing me to charge 3 laptops, while completely disabling USB C4 and the USBC A1 and A2 ports. The A1 and A2 ports combined take up min 15W, but they can also be disabled and all power routed to the USB C ports.
ACCURACY OF BUILT-IN POWER METER: I found the combined accuracy accuracy of the built-in meter spot on, however the individual channels were sometimes way off. For e.g. when charging my 250W anker power bank with 2 USB cables, the charger display indicated 75W + 75W for each USB C port. This was different from the power input shown on the power bank, showing 110 W + 40 W input for the USB C ports. When added individual power meters to each USB C cable, it confirmed the 110 + 40 power distribution, the power bank figures' being correct. Not that important but worth mentioning.
THERMAL STRESS TEST: testing the unit at 250V voltage in the UK, when running at full load for about 20 min - while topping up my 250W Anker power bank and charging some other devices - the charger just got warm, not even hot. I do not have the means to stress test the unit at 250W for extended periods of time, but in real life I rarely (if ever) need that much sustained power. Most of the time I am charging 2 laptops at around 170W combined power, which the unit handles well at 250V mains. So overall, it works well.
ONLINE CONNECTIVITY: the wifi connectivity is needed for the following:
- Firmware updates - new updates do not show and can't be performed via Bluetooth connection only
- Long-term charging history graph, updated every 10 mins.
Short-term charging history, updated every second, showing the last few minutes is always available. All other features, custom charging mode etc. are also available without a wifi connection, via Bluetooth only. At this firmware, with no wifi connection, I have not seen red warnings in the software, every functionality being available and operating normally.
FACTORY RESET: performing a factory reset will only reset the default menu parameters (e.g. screen brightness, timeout, charging mode defaults to AI mode etc.). A reset:
- Does NOT erase previously created custom charging profiles.
- Defaults the connectivity to no connection. One has to reconnect via Bluetooth. Wifi connection is disabled, although the wifi credentials are not wiped but still present to facilitate future reconnection. To re-establish wifi connection after a reset, the user has to expressly initiate the wifi reconnection manually.
Hope this point is useful info for privacy conscious users.
