What is a power bank?Power banks. Portable power stations. Chargers that can go where you go—without the need to plug into a power outlet. This is why we're all here. I've tried more than a dozen of the things to help point you in the right direction of how to navigate this complicated space of power banks.
How much power does a power bank give a phone?Our testing shows that a power bank can offer your phone between 70-80% of the power it contains, or more depending on the battery. It loses the rest due to the inefficiency of the power transfer. That means a 5,000 mAh battery can fully charge a phone with a 3,500 mAh battery, like an iPhone 16.
How much power does a power bank charge?Power banks charge at around 80% efficiency. Most premiere flagship phones have a battery around 5,000 mAh, but a 5,000 mAh battery pack cannot charge your phone to 100%, it will be closer to 80% charged. We've tested these battery packs to see how many times they can charge an average smartphone, and how efficiently they transfer power.
Should you invest in a portable power bank?The good news is you can prepare for—and avoid—these stressful scenarios by investing in a portable power bank. Also known as mobile chargers or battery packs, these nifty gadgets serve as a lifeline to your dying electronics by recharging battery power when needed.
What is the fastest power bank?The Anker MagGo Power Bank (10K, Slim) is our top pick for a reason: it combines shockingly good performance with a premium, portable design. Its charging capability is its standout feature, proving to be the fastest MagSafe power bank we’ve ever tested, capable of charging an iPhone in under two hours.
Which power bank should I buy?If you have an iPhone or a newer Pixel, or a phone case with magnets, this is the first power bank to consider. It's one of the fastest magnetic charging power banks we've tested, and our experts continue to carry this power bank as a daily battery pack to use on the go. 2. Iniu P50
