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.
What is a 25,000 mAh power bank?
25,000mAh for Long-Haul Power: Set off on extended journeys with a huge 25,000mAh capacity that supports your devices through multiple uses, complete with 100W ultra-fast recharging that fuels the power bank to 30% in just 20 minutes.
Should you buy a portable battery or power bank?
Watching your phone or tablet steadily run out of power when you're nowhere near an outlet is stressful. But there's an easy solution: a portable battery or power bank. These are available in many sizes and capacities and can include handy features like fast charging and extra ports.
Which power bank is best?
All of the power banks on this list passed our testing, traveling with us on the road and powering our devices at home. Anker is the best in part because it packs more power into its batteries at a lower weight. Its batteries charge faster than competitors. Its small Anker Nano battery has the best power-to-weight ratio of any battery on our list.
How many charges can a power bank charge?
To estimate the number of charges, use this formula: (Power Bank Total Capacity × 0.65) ÷ Device Battery Capacity. For example, a device with a 3,349mAh battery can receive approximately 4.8 charges from a 25,000mAh power bank. How long does it take to recharge the power bank?
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.
