Chromebook Charge Light Flashing

flashing lights indicate charge level roughly.

As many others mentioned in the reviews, these batteries are now new old stock, as the newest ones were made in 2022 and will arrive completely discharged. DO NOT give up on them - the charger will initially show an error (chamber and calibration light flashing) - keep taking the battery off and putting it back on, and eventually it will start to charge. The key is to not leave it in the charger if the charger is showing the error code, you have to remove and replace the battery until the charger shows that it is charging (chamber light and 50% light flashing). After a few hours the 50% light should glow solid and 80% should start flashing, and eventually it will charge fully

Does its job. I like how the flashing of the lights lets you know where you are in the charge cycle.

Works great. The flashing lights are an easy way to see how the charge is progressing.

but it is unsettling to have the upstream light flashing

It seems well-made my Chromebook looks comfy in it.

Works perfectly on Mac and and ASUS Chromebook. I use it for an external monitor on my Chromebook. I use the power pass through to charge the chromebook as well as the monitor interface. On the mMaqc to simply use it as USBA ports (Mac is USB C and Thunderbolt only). Works perfectly.

[This review was collected as part of a promotion.] I was really needing a charger that could charge my iPhone iPad and Chromebook all at one time and this was the best thing to receive. It charges them all at a decently fast pace and I never have to worry about remembering to charge them with having all my charge cords in one place

[This review was collected as part of a promotion.] Works to charge both my Lenovo laptop and Chromebook at a decent speed. Very similar to the original cords that came with those devices. Can’t speak to durability yet but hoping it will last.

This is a very nice headlamp, without two levels of white light, a red light and a flashing red light.  Having the battery pack on the back makes it much easier to balance and the straps are adjustable over a wide range.
