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

What is a power bank?
A power bank, also known as a portable charger or external battery pack, is a portable device that stores electrical energy and can be used to recharge electronic devices such as smartphones, tablets, laptops, and other gadgets when they run out of battery power. Power banks typically contain lithium-ion batteries and come in various capacities, sizes, and shapes to suit different needs. They are convenient for charging devices on the go, especially when access to electrical outlets is limited.

How to charge your power bank or portable charger?
Charging a power bank is straightforward. Simply plug the power bank into the charging cable, then connect the cable to a power adapter or USB port on a computer. Wait for some time until the power bank is fully charged. Once complete, disconnect the charging cable, and your power bank is ready to use.

How much capacity power bank do I need?
The capacity of your power bank depends on the devices you need to charge and their battery sizes. If you're charging just a smartphone, a power bank with 5000mAh to 10000mAh should suffice. However, if you're charging multiple devices or larger ones like tablets or laptops, you might need a power bank with 20000mAh or more.

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)

I'm going on vacation soon and looking for a reliable power bank for iPhone 17. My usage will be something like starting the day around 7 AM and finishing at 10 PM (then charging everything again), with lots of photos, videos, and map usage.

Anker Nano. Picked mine up before I returned my iPhone Air. Gets hot like most MagSafe chargers but the phone never got hot while using it and honestly it seemed like the battery would throttle charging to keep it from going over ~100°F I’d also recommend the Anker Zolo if you want faster charging via USB-C. It’s a bigger battery, 10k mah but it also doesn’t get as hot while charging. I usually take that one if I’m going to have to top off my wife and daughter’s phones as well.

r/onebag on Reddit: Any good slim wireless power bank for iPhone? Trying to keep my pack light
July 14, 2025 -
I usually keep a wired charger in my bag when I go out. Works fine and charges fast. But I don’t really care much about speed, just want something easy to use. Lately I’ve been thinking of switching to a magnetic one. I use a phone lanyard when I’m out, so it’d be great to charge while it hangs there.
Just looking for something I can snap on and off quickly. Budget’s around $50. Based in the US. Thanks in advance!

Beware that wireless charging doesn't just mean slower, it also means less efficient. For each watt in your battery, fewer watts will arrive in your phone (they get turned into heat). Put differently, you will probably need to carry more grams of power bank with a wireless charger compared to a power bank + short cable. (I say probably, because I haven't weighed a small cable nor checked the exact decrease in efficiency). I have seen online (unverified) claims that the decrease with MagSafe is around 25-33%. Frankly in my humble opinion the idea of wirelessly charging power banks is just utterly stupid. How did we go from swappable batteries (100% efficiency) to wired power banks (around 50% efficiency) to wireless power banks (let's say 35% efficiency)... 🤦. It's nearly 3 times the weight and energy used to achieve the same thing 😅. Sidenote: Some more fancy phone nowadays support bypass charging, which means that the powerbank is used to directly charge the phone, rather than the phone's battery. Sadly your phone (iphones) does not support this (nor mine, really wish it did though 😅).

I usually stay out the whole day while traveling, so maybe 10000mAh fits better.

September 30, 2025 - 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.
