At CES 2019, a Navitas representative explained GaNFast technology and showed us production units of GaN chargers.
I’ve been looking for a battery bank I could use with my 15″ MacBook Pro however most brands only charge between 18-30W which is too little juice. However, I found a 45W battery bank and wanted to share my test results with you in case you were looking to extend the battery life of your Macs.
WHERE TO BUY
Cygnett 45W PD: http://vtudio.com/a/?e=cygnett+45W
Cygnett 60W PD: http://vtudio.com/a/?e=cygnett+60W
MacBook Pro: http://vtudio.com/a/?a=macbook+pro
Usually I get 2-4 hours battery life on my 2018 MacBook Pro depending on how heavy I push it. To get longer battery life I tend to always disable Turbo Boost which makes it run slightly slower but doubles the battery life.
One thing to note about these Macs is that when Turbo Boost is being used the battery drains by 0.2% per minute even with the Official Apple 87W charger is plugged in – make sure you plug it directly into the laptop and not via a USB-C adapter as it drains a lot more through one of those – yes even the official Apple USB-C adapters.
With one of these 45W battery banks plugged in the internal laptop battery still drains by 0.9% per minute when being maxed out but if you’re just using apps normally it does indeed still manage to charge the Mac. For example I had Final Cut playing back a video with the iOS simulator and YouTube open at maximum brightness and it was charging at 0.3% per minute. Which is great.
They are a bit expensive, but they seem to work as described. Something to check out is their new 60W PD power bank – they are a little bigger in size but they’d be even more suited for a higher spec’d 15″ than the 45W.
