multiple full charges and compact enough to easily fit in a backpack/pocket are my priorities I'm sure you know this, but always good to remember that these two priorities are in direct opposition to each other. I have a 20000mAh that can handle multiple full charges but is big and heavy and I would not enjoy carrying it in a pocket. I've actually stopped bringing it on trips because I never needed that much juice before I got to a power outlet (YMMV of course). It fits just fine in a backpack but is heavy. I have a 5000mAh battery that is light and pocketable to carry all the time. Not getting more than 1 charge out of it though. Answer from alamar99 on reddit.com

Anker 737 should do you well. I try to make sure the capacity is at least 20K mah and that it can support fast charging (need at least 20W)

June 10, 2024How Does Wireless Charging Work?
Wireless charging has become popular because it enables you to power up compatible devices without the need for a cable. Qi is the dominant standard for compatible Android phones (up to 15W), while Apple iPhones rely on MagSafe charging (up to 25W). iPhones will also charge wirelessly on Qi chargers (7.5W) and Qi2 chargers (15W).
Some battery makers have built Qi or MagSafe-compatible wireless charging into the surfaces of their portable batteries. Such batteries mean you can leave the cables at home.

What Is Fast Charging?
Another factor to consider is how quickly a power bank can charge your device. Battery output is measured in voltage and amperage. Amperage (or current) is the amount of electricity that flows from the battery to the connected device, while voltage is the amount of potential energy. Multiplying volts by amps yields wattage, which measures total power. To make devices charge faster, manufacturers either vary the voltage or boost the amperage.
Today’s devices support a wide range of rapid-charging technologies, such as Qualcomm Quick Charge, USB Power Delivery (PD), or proprietary fast-charge systems like OnePlus’ SuperVooc.
Quick Charge works by increasing voltage rather than amperage. This standard typically allows you to charge supported phones to 50% capacity in 5 minutes, which is especially helpful when you need power in a pinch.
Two compatible devices with Power Delivery can negotiate the fastest charging option available based on the charger, cable, and circuitry. It also allows power to flow in both directions.
The most common phones (those in Apple's iPhone and Samsung's Galaxy lineup) support charging rates of up to 45W. It’s best to look for batteries that get as close to your phone’s maximum rate as possible.

Should You Buy a Battery Case Instead of a Power Bank?
If you often forget to carry your backup battery when you need it most, consider a dedicated battery case instead. These cases combine the portability and protection of a case with extra battery capacity to keep your phone fully charged at all times.
There are several drawbacks. First, they have limited additional capacity. Second, they are limited in terms of the number of phones they support (mostly iPhones, Galaxies, and Pixels). Third, you can't charge much else with them. Stand-alone chargers might also allow you to charge a smartwatch or wireless headphones.

Best Portable Chargers and Power Banks for Phones and Laptops - Consumer Reports
September 30, 2025 - Battery capacity is one of the most important factors when choosing a portable charger, says CR testing engineer Bernie Deitrick. These backup batteries typically have capacities between 5,000 mAh (milliamp-hours) on the low side and 30,000 mAh (or more) on the high end. To choose, consider what you need to charge. An iPhone 16, for example, has a battery capacity of about 3,500 mAh, so a 5,000-mAh portable charger can only charge it once from zero or top it off a few times.

September 19, 2025 - Although its capacity is significantly smaller than those of other chargers on this list, the Moft is the only one I’d be willing to drop into my pocket rather than a bag: It has roughly the same dimensions as a stack of eight credit cards, and its surface is a faux leather that feels nice to the touch — every other portable charger I’ve tested has had a plastic casing. The EcoFlow Rapid is about the same length and width, though about double the thickness, and has more than twice the battery capacity. The Moft power bank is especially useful for iPhones, as it uses MagSafe as its primary method of charging.
