GoKawiilIt is small but it is mighty Lisen/CNET
A portable power bank is basically a no-brainer when you're a frequent traveler but they can add quite a bit of weight to your bag. I purchased this Lisen Qi2 15-watt ultra-slim magnetic charger hoping it would reduce some of the weight while still being an effective back up. And I'm happy to report it's been one of my favorite purchases of the year.
True to its claims, it has charged my iPhone 17 from 5% to 50% in under an hour, but the best part is you can charge it while it's in your pocket. This thing is so slim, it just magnetizes on and you can slide the phone and charger into a pocket or purse and power up while you wander.
It only weights 3.6 ounces and you can use your phone while it's charging without a bulky cord. The one drawback is that it only gets your phone to 80%, so it's more of a backup than a big power source. Still, it's saved me more than once during deplaning delays and on-the-go activities. It may not be the biggest, baddest power source out there but it makes up for that in size and convenience.
I paid $40 for mine, but you can pick up the same Lisen charger for $25, a decent $15 price break thanks to the last wave of deals coming in during Amazon's Big Spring Sale.
