Flashing Green Light Macbook Charger

Very good device but hardly fast speed and external light keep flashing green. But over all everything seem fine

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

but it is unsettling to have the upstream light flashing

Sturdy charger, green lights indicate when each battery is fully charged. Light weight.

This is so much better than the single charger that comes with the camera because it has two chargers AND mostly because you can tell how fully charged it is without just waiting for the charger to stop flashing. Huge improvement.

I love the Watson charger. It's fairly fast and I love the fact that it changes from a red light when charging to a green light when fully charged. I also like the fact that it doesn't require a cord to plug it in. You just pop out the prongs and plug them into the wall outlet. Sweet!

I lost my charger for my camera and wanted something exactly like it. This charger is the same, small, plugs into the wall, and shows green light when fully charged. ... Just like new.

I used this charger to charge the battery for my Olympus 8010 camera. When a depleted battery is placed in the charger, a red light goes on. When fully charged, a green light goes on. This charger will not overcharge the battery but bring it to a full charge, so leaving it in when the green light is on fully tops off the battery charge. The battery seems to have a longer charge as a result. I really like this battery chaarger.

I've only charged my batteries once, but the charger worked just fine. I like the red/green light indicator for charging status. I never would have found the charger I needed without the help from the Live Chat pro. Thank you!

No problems with this charger. The indicators progress from 1 green light to 3 greens lights. The indicators disappear when fully charged. If I was deigning this device I may have a different setup for the lights but once you understand, it works fine.
