What is a power bank?
A slew of terms are used to describe power banks, including portable batteries, portable chargers, external battery packs and even, somewhat confusingly, USB chargers, which is what wall chargers are often called.
How much Mah will a power bank retain?
If you maintain the power bank well, you can expect from 80% to 90% of the nominal mAh to be retained. Looking For The Top Power Bank For Your Portable Device?
What features should you consider when buying a portable power bank?
Pass-through charging is another feature to consider; with it, you can charge your device and a portable power bank simultaneously. That's convenient if both your phone and backup battery are running on empty.
Should I buy a small power bank or a large power bank?
Small power banks can be great for an occasional top up of power on the go – they’re light enough that you’ll hardly feel the weight of them in your bag. Large models give you more juice but are less portable.
Which Anker power bank is best?
Anker’s well known for its lineup of power solutions, so it comes at no surprise that the Anker Prime 27,650 mAh power bank is our favorite large capacity charger. With its generous battery, it’s more than capable of charging small stuff like your phones and wearables — but it’s also powerful enough to charge laptops too.
Do I need a power bank?
If you are charging a small smartphone, a simple power bank will suffice. If you plan on charging a laptop occasionally as well, or many devices at once, you'll want a power bank with more power and more features.
