If you are trapped in a difficult decision — choosing the best power bank for your MacBook, you’ve come to the right place. We have listed several factors that can help you distinguish a good power bank from others, and the top selections that can keep your MacBook powered longer.

Using your laptop away from a plug socket can easily lead to a dying battery, which might be a nightmare for many people. This is why portable laptop charger battery packs are so popular and essential today. Portable power banks have been around for years and, for the most part, it has been pretty straightforward to judge whether it is a good power bank. There’s storage capacity (measured in mAh), power conversion rate, portability, and of course, other things like size, weight, durability and number of ports.

Factor #1: Storage Capacity

If you want to choose a power bank for you MacBook, the first factor you have to consider is if it can fully charge your MacBook. Most power banks aren’t powerful enough to charge a laptop, but there are a few exceptions. Power banks that support USB Power Delivery (USB PD), which is a fast charge standard, are able to control more watts and deliver more power — basically, they’re able to fast charge larger devices (if those devices support it). USB Power Delivery only works with a USB-C to USB-C connection, so if you have a 2016 MacBook Pro or new laptop that charges via USB-C, you need a power bank that supports this technology.

Factor #2: Conversion Rate and Price

There are other factors to consider before buying a portable power bank — such as price and conversion rate. There are some power banks in market with extremely low prices, but only have a 6000mAh capacity or slightly higher, which is not reasonable. The higher the conversion rate is, the higher the price will be. The truth is unreliable batteries may be made of old laptop batteries. At present, power banks priced at over 20 dollars is relatively reliable. The power conversion rate of qualified products should be more than 70%, and better power bank can be even more than 75%. It means the nominal 5000 mAh power bank which can actually output at least more than 3650 mAh can be called a reliable power bank.

Factor #3: Portability

One of the main reasons to choose a power bank for our digital devices is its portability. For a long tip, a portable power bank can not only provide power for you devices but also relieve the pressure from you. The best portable power banks can even replace your original laptop charger altogether, providing you with an uninterruptible power supply wherever you happen to be. So it is a must for us to think about portability when we choose a power bank for our MacBook. After all, the MacBook is heavy enough to carry.
