Today, we’re reviewing the Innergie USB-C charger. Innergie is the consumer brand of the famous Delta power supplies used in labs in universities and R&D companies.
Although it worked fine with our Chromebook, in the past we’ve had trouble with this charger on Apple equipment. But since recent firmware updates on macOS, we decided to revisit this charger. So how does it look like?
So around macOS version 10.12.2, we tested this charger and this caused some problems for us; the laptop would repeatedly charge, then disconnect, charge, disconnect et cetera. We decided to not recommend the charger anymore but with the latest macOS update to 10.12.5, re-tested and found that the problem had disappeared. We suspect Apple fixed a bug in the USB-PD firmware of the MacBook Pro, and have been using this charger again.
Now the question may come up as to why would one use another brand of charger instead of the one that comes with your laptop? The reason is that this is an incredibly useful and well-designed charger. Here’s our highlights.
As you can see in the picture, the charger was definitely designed to be used while traveling. The cable is supple and comes with a solid clip attached, so you can wrap it neatly. The AC cord is nothing special per say, just that it’s a regular C8 connector. This means you can replace it with something country-specific while traveling, or just replace it with a longer or shorter cable.
Highlight number two is that this charger is very light and compact; for example the brick that comes with a 15″ Apple MacBook Pro is easily twice the weight and size. On the other hand, it’s slightly bigger than the charger that comes with a HP Chromebook 13 G1, which delivers 30W.
Third is that the charging cable is a so-called captive cable. It can’t be removed from the charger, nor can it be used for example as a data cable.
Why not this charger?
This brings us to some considerations why you’d want to look at another charger. Some people dislike captive cables. They can’t be replaced, nor can they be used in a pinch for hooking up another device.
Also, this charger delivers a maximum of 45W. That’s more than enough for most Chromebooks and laptops like the Razer Blade Stealth and the Apple MacBook, but the 2016/2017 MacBook Pro comes with a 60W (for the 13″) or 87W (for the 15″) charger. This might not be a problem though: on my 15″ MacBook Pro, I personally use a 45W charger on a daily basis. Average power usage is 12-15W, or 25-30W when an external monitor is connected.
This charger is not suitable if your laptop comes with a larger than 60W charger, and you peg the CPU/GPU for more than an hour. For everything else, it’s fine.
An earlier version of this charger has also been reviewed by Nathan K. on Google Plus, a former Google engineer who is normally very, very strict but gave it the tl;dr: EXCELLENT charger verdict. GTrusted has done several analyses on how the charger behaves on the 2015 MacBook and the LG G6 phone.
We definitely recommend this charger and have added it to our selection.
