Why read this review of wireless batteries?
I’m a regular business traveler and am always looking for ways to make my travel easier / more impactful. As a former Army officer, I am always thinking about how to keep my communication equipment (these days a phone and laptop) charged when on the move. When I was a consultant, we said “ABC: Always Be Charging” for when should you top off the battery of your devices. I’ve been using the Baseus wireless batter for the last year.
What is MagSafe wireless charging for iPhone?
Wireless charging is a technology where electric current is transmitted from a charger onto a device without the use of wires. It is accomplished by electric induction from an electromagnetic coil in the charger. This coil creates a magnetic field that is received on the phone and added to the battery. While wireless charging has been around for a few years, the MagSafe technology makes it convenient to move around with a battery attached to the phone.
What is the white circle on my iPhone case?
The white circle is part of the MagSafe charging system that Apple developed and implemented starting with the iPhone 12 in October 2012. It’s a magnetic system that secures the battery to the back of the iPhone and positions the battery to wirelessly transmit energy to the phone.
Both the iPhone and IPhone case both have the white circle so that the magnetic system works.
How well does the Baseus 20W wireless battery work?
This battery is extremely easy to us. The USB C port allows you to charge the battery from any way outlet or USB port. The three white LEDs indicate the level of charge.
Using the wireless battery takes two easy steps.
- Depress the button to activate the battery
- Attach the battery to the back of your iPhone
Pros of Baseus 20W battery:
The Baseus wireless battery charges the iPhone extremely well. I’ve found the wireless charging to be extremely convenient when I’m flying and there aren’t any outlets at my seat or the outlets aren’t working.
Compared to Apple MagSafe Battery Pack, the Baseus wireless charger is cheaper and packs more electrical capacity. While the Apple battery does transmit at a higher voltage, it doesn’t contain enough power to fully charge an iPhone. Also, the Baseus battery uses a USB C connector (instead of the Apple lightning).
Cons of Baseus 20W battery:
The MagSafe battery seems to charge a bit slower than a Lightning cable but I do love the flexibility of wireless. Because of the heat loss during the charging process, you aren’t able to access the full 6000 mHa capacity of the battery.
Bottom line, for the low price of the Baseus charger, it should absolutely be in every business travelers briefcase. For other travel must have’s, check out our best business travel tool listing.
Does the Baseus 20W MagSafe wireless battery work with other devices?
Unfortunately, the Baseus is designed specifically for modern iPhones (iPhone 12, 13, 14, 15). The battery actually does work on an iPhone 11, but it’s charging is limited to 7.5W, so it will be relatively slow. Some Android devices may be able leverage MagSafe technology, but you’ll have to do a bit more research (see this article for first steps).
What are mHa for phone batteries?
mHa (milliampere-hours) describes the electrical capacity of a battery. It’s the amount of energy that the wireless battery (or any battery) can hold. The battery on your iPhone or reMarkable 2 also has a capacity that’s measured in mHa (though we don’t often talk about it). The Baseus 20W wireless battery has a capacity of 6000 mHa or 23.1Wh (watt hours).
One way to think about mHa on a phone or battery is like a gas tank on a car. The higher the mHa the larger the capacity of potential energy. Just like a gas tank, the mHa doesn’t have anything to do with how that energy is consumed.
For reference – an iPhone 14 has a standard battery capacity of ~3,500 mHa. This means that Baseus wireless battery has about twice the capacity of the phone (though there is a bit of heat loss during charging).
FAQ for MagSafe wireless charging
Yes! Wireless charging has been mainstream on the Apple iPhone since 2017 and has continued to improve. It does not present a threat to your phone.
MagSafe is Apple’s proprietary wireless charging technology that combines a magnet for connection and transmission/reception coils for transmitting energy. The transmission of energy occurs by the battery energizing an electromagnetic coil and then the emitted waves are received by a coil on the iPhone.
No! Additional heat is a byproduct of the wireless charging process. If the phone starts to get really hot to the touch (or shows the high temp warning), you should discontinue charging until the phone cools off.
The biggest key to keeping your phone cool is to minimize other external heat sources (like being in direct sunshine). Also avoid accidently insulating your phone so that it cannot shed excess heat (like keeping it in a padded pocket).
