Why we chose this
Power banks are a category where everyone settles. The Prime is the first one we tested where we stopped resenting the weight in our bag, because it routinely replaced the wall charger entirely on day trips. The display alone is worth the price difference over a generic 100W bank.
The review
Anker's Prime line takes the boring power bank and makes it feel like a luxury product. The 27,650mAh / 100Wh capacity is the maximum allowed in airline carry-ons, the three USB-C ports each push 100W (with smart sharing across them), and the small front display tells you exactly how many minutes of charge are left at the current load — a feature so obviously useful it's strange every power bank doesn't have one. The aluminum unibody runs cooler than the GaN bricks we tested it against, and the optional MagSafe-compatible charging base means you can leave it on a desk and use it like a wireless platform when you're not traveling. If you're someone who carries a laptop, a phone, headphones, and a tablet, this bank charges all of them without thinking — and the smart power sharing means it gives the laptop the lion's share when plugged in alone, then redistributes as devices join.
