this charger is a crap. it doesn't fully charge batteries and doesn't properly identify current charge. neither lithium, nor NiMH. probably because it's not smart enough to make short pauses between cycles to measure the voltage. my old no-name charger does a better job.

Legend, it works for my 2012 macbook pro, the key is to hold power button first and plugin the power

thank you

Life saving hack bro....thanks alot

THANK YOU SO MUCH!!

Just got one from Goodwell for $2.99. No USB cabal, instead it came with a power adapter, it also came with two of the smaller lenses that have different magnification.

It work for me

Do it wont charge alkaline batteries? When I put alkaline it directly reach to 100%.

What a relief! Took me actually paying attention to the instructions and it worked. Thank you!

You are such a legend bro ❤

This is amazing! Worked on my old unchargeble old macbook pro. Thank you!

It works

using shift-control-option-power method worked for me, thanks a lot! i was thinking about to replace the battery, but you saved my day. Thank you a lot!

This worked…. Thanks

Any idea how to root it so I can install a newer version of android on it?

Wow it works! I tried many times it always boot now I can sell mine and teach the new owner how to turn it on.

Thanks you so much! My Mac booted after so many years! The battery seems to be dead.

It works for me. Macbook Pro 2015 early retina display

Hey 3 years later and it didn’t work.

I tried all day to get my mabook pro to wake up. Apple help was useless. On my screen a "battery charge symbol" was displayed. I watched 20 seconds of this video and my laptop powered up on the first try. Thanks!

It works thanks

Just finished the swap out. Plugged it in and attached to MacBookPro. The light on the end lit-up green but flashes -- it flashes briefly at 2-sec interval. The Charge lightning bolt on the screen goes on and off in time with the green light as it goes on and off. Thoughts?

Yay! This worked for me on a deeply discharged battery on my MacBook Pro.

Thanks i just ordered the charger, and subbed

Unfortunately didn't work on my 2012 mbp

it works!!!!!!!🏩

idiot, get a life, what have you shown us, nothing. what a fkn moron, people just sseking attention, what a moron

This guy knows what he's doing. Worked and Mac booted, thank you for the upload

I legit have a 2012 and it didn't work for shit

this is the correct way finally

Thanks man, this is the only "fix" that worked for me! 10/10!

I started questioning my life choices. I watched 30+ minutes of someone charging batteries, on the same make charger I already own, and I enjoyed it. I'm pretty old though, so maybe this is practice for my retirement in 30 years' time?

Thank you.

А какая зарядка может толкнуть аккумулятор?

this hell worked ! but why my mac only powers on using this method ? also the fans are running full speed, how can i fix that ?

bro please give the link

Legend!!!!

Nice review bro thanks

yes its work for my 2011 macbook pro Thanks.

Question: if the battery is dead does the magsafe cord not light up anymore? Cause yours doesn't seem to light up same as mine but on my macbook it still holds a little charge its stuck on 14% when plugged in but the percentage doesn't go up or down when plugged in, but as soon as i remove the cord it still stays on at 14% and as i leave it the percentage goes down to 13% but if i plugged it back in it stays to that percent (13%) it won't charge up the mac also shows a message at the top "battery is not charging"

It worked, but if I disconnect the cable it dies every time- do I just need a new battery?

Thank you so much, my battery was not dead but it was completely unchanged and after this the SMC reset worked, just like you showend on the video.

Actually saved from me from going to the Apple Store 😭

Place them in series so that you know that you're measuring the same current. Sometimes the meters show the power consumed by the meter. Sometimes when current flows in one direction, the current of the meter is included and in the other direction it is not. Did you try switching the Arduinos in case one was consuming more power than the other?

I got the black kewiesi one, I tried to calibrate this thing and has since messed it up as it just keep giving the wrong readings now, I can't get any reading higher than 0.18A now, It's impossible everything has such a little current right? Could you tell me how to get it back to factory default? secondly, what is the thing called calibration, I followed the instruction that says one should hold the botton then plug in the tester which I did then, next, I have to double-press, to change the arrow from forward to up then press one more time to change the arrow upwards then press once to increase the current that's the +000 display, what exactly is this? I'm required to increase that thing(which is the current) then double press for the arrow to charge to forward and press once one last time before ending the cablbration but, after doing all these it started giving wrong readings. What exactly should I increase the current to when I'm pressing once between those arrow changes process? lord I can't stand electronics.

Thanks for this works

Worked

Is it normal for the light to go out when the batteries are charging?

Is it safe?
