MacBooks must generally be powered down in order to charge from these batteries. So far, only the expensive Mos Go (see below) can provide more power than a Macbook draws while it is on this is because the Mac OS in its current version thinks that it is connected to a wall outlet when connected to an external battery. Note for USB-C MacBooks and External Batteries We have more on charging speeds below for each battery. You don’t need Qualcomm Quick Charge if you have a USB-C device. Some devices that still have Micro-USB connections employ Qualcomm Quick Charge technology to get around the limitations of micro-USB this enables fast charging over those connections. USB-C devices employ various technologies to enable quick charging of their devices. Understanding Quick Charge with USB-C and with Micro-USB Batteries, wall chargers, and computers have USB-A outputs. USB-C will likely become standard for all sorts of laptops, tablets, phones, headphones, and other electronics in the near future, but many still port micro-USB inputs, which can only be plugged in one way (see the picture below). USB-C connectors can be plugged in upside-down or rightside-up. USB-C now connects the latest Nexus phones, the OnePlus 2, Apple Macbooks, Meizu PRO 5, Gionee S6 & Marathon M5 Plus, Xiaomi Mi 4c & Mi 5, LeEco, Microsoft Lumia 950 & 950 XL, Moto Z & Z Force, and the Samsung Galaxy Note7, among many others. This is why it was particularly important for us to look at multiple press and user reviews for each battery. It is important to pay attention to how well these batteries work in the real world, and across multiple user experiences. Energy is lost in any energy transfer, and lithium-ion batteries can’t ever reach exactly 100 percent nor can they be completely discharged. The mAh ratings (usually shoehorned into the batteries’ names on Amazon) don’t tell you exactly how much power you’ll get. Ratings of mAh are General Indicators - Not the Exact Amount of Usable Power It’s a little more battery to carry, but they do at least tend to carry enough juice to power your smartphone for up to a week. Most of the options here are around 6 x 3 x 1 inches and weigh 10-15 ounces. There are currently no mini pocket-sized options for USB-C batteries - at least not in the gloriously small “credit-card” size you find for micro-USB external batteries. ![]() ![]() We expect more options and will keep abreast of them, updating these recommendations as needed. There are not a lot of options for USB-C external batteries at this point, as only some of the newest phones and other devices take advantage of USB-C.
