Always have power when you need it.
One of my biggest frustrations is going on a trip and not having adequate power outlets. Last May, my family and I made a weekend trip to Nashville, TN and found ourselves scrambling to find enough places to plug-in our many devices. What we really needed was a multiport power adapter like this travel charger from Satechi. Satechi makes some fantastic, premium products for all types of users. They tend to specialize in Apple-based accessories but have quite a few categories of products that will reach beyond that manufacturer’s wall. One such device is the Type-C 75W Travel Charger.
I have to pause for a moment to point something out — it’s called a ‘travel charger’ but isn’t really a travel charger. When I hear the phrase ‘travel charger’ I think of a wall adapter that has many power options depending on what region of the world you are traveling it. Even though this product doesn’t match the mental image of a ‘travel charger’ it does provide a broad input range (100-240V) for international voltage requirements. This power station is very portable and will transport/pack easily. It measures 4″ x 2.63″ x 1″ and has a power cable length of almost 4 feet. It’s very lightweight at only 11 ounces. The AC power cable is removable for even easier packing or exchange to a different international power adapter.
There are four ports available on the Type-C 75W Travel Charger:
- One (1) USB-C: Provide power delivery up to 60W maximum
- One (1) USB-A with Qualcomm Quick Charge 3.0
- Two (2) USB-A (5V/2.4A)
With these specs, the Satechi Type-C 75W Travel Charger is designed to be compatible with numerous devices including: MacBook/MacBook Pro (up to 60W), iPad Pro/Air/Mini, iPhone X/8 Plus/8/7 Plus/7/6 Plus/6, Nintendo Switch, Samsung Galaxy Note 8, S8/S7/S6 and most smart phone, tablet and USB devices.
With batteries and charging stations alike, I prefer to do three standard tests. First, I charge multiple devices (if simultaneous charging is available) for an hour. Next, I look at how hot the charging device gets while sending power out to connected products and finally, I measure power delivery using a USB Digital Tester. I have included the results of my tests below.
I chose to charge my two most important devices — my iPhone 7 and my 2016 13-inch MacBook Pro with Touch Bar. The iPhone 7 typically charges using a Lightning cable connected to a USB charging device. It has a battery capacity of 1,960 mAh and will last approximately 10-12 hours depending on connection and use. The MacBook Pro will last up to 10 hours on a full battery charge and needs a 61W USB-C power adapter (and compatible cable) to recharge. Both of these devices have very different charging needs and I really wanted to stretch the figurative legs of the Satechi travel charger. I had the MacBook Pro plugged into the USB-C PD port and the iPhone 7 was using the USB-A QC 3.0 for the first four readings. I switched charging ports on for the iPhone 7 for the last few readings. Here are the results.
|MacBook Pro||iPhone 7 (USB QC 3.0)||iPhone 7 (USB 5V/2.4A)|
In one hour, the MacBook Pro gained 45% battery charge for a charging rate of 0.75% per minute. The iPhone 7 gained 54% in 30 minutes using the QC 3.0 port and 18% using the 5V/2.4 port. This was an average gain of 1.25% per minute.
How Hot Is It?
While this might not be something you readily think about when you are looking for charging accessories, I think measuring the heat of a charging device is very important. If something gets too hot, it could cause damage to your connects device or surrounding objects. So, in order to measure the heat coming off of the travel charger, I used an Infrared Thermometer to test how hot the Satechi charger go while it was charging my MacBook Pro and iPhone 7. At rest, with nothing actively charging, but plugged into a wall outlet, the charger is around 85º F on average. I took several surface readings to confirm this.
Throughout the course of testing the battery percentage gain on the devices, I would touch the top of the charger and then use the thermometer to get a real temperature reading. The longer the devices were charging, the warmer the surface of the charger got. And, this was only with charging two devices simultaneously. See the chart below for the complete details on this round of testing.
Got More Power?
When it comes to testing the power delivery of a device, you want to look at how well it charges on other devices for a comparison. In the science world, this is called a ‘control’ within an experiment. For the MacBook Pro, I used the 61W Apple Power Adapter and for the iPhone, I used a portable battery from Anker (USB 5V/3A). With both power device options, I used Nomad Ultra Rugged cables (Lightning and USB-C). You will see that in all the results that the power delivery amount was the same for each device and easy power delivery option. There was a very slight variation in the readings, but not enough to think that the Satechi Type-C 75W Travel Charger is not doing its job.
|MacBook Pro||iPhone 7 (QC 3.0)||iPhone 7
|Satechi Type-C 75W Travel Charger||20.3V/1.24A||5.02V/1.57A||5.08V/1.57A|
|Apple 61W Power Adapter||20.3V/1.53A||–||–|
|Anker PowerCore+ 26800 PD||–||5.06V/1.57A||–|
The Satechi Type-C 75W Travel Charger is a great traveling companion. It provides sufficient power for devices and operates as advertised. The only thing I would be cautious about is leaving it alone for a long period of time due to the heat. Satechi makes really solid products and I don’t think that there should be any worry about the charger overheating but users should be aware that it does get warm. I think the Satechi Type-C 75W Travel Charger is a really nice product and I look forward to taking it on my next trip.
