The everyday power bank: what carrying one for years taught me
I carry an Anker PowerCore 10000 whenever I go out, and I’ve been using it for about three years. Here’s what that suggests about choosing an everyday power bank, followed by a comparison of three current Anker options.

What I actually carry
I carry an Anker PowerCore 10000 (model A1263) whenever I go out. I’ve been using it for about three years, and it charges my phone about three times.
The label on mine lists 10000mAh / 36Wh, input 5V⎓2A, and output 5V⎓2.4A.
What that taught me
- 10,000mAh is a useful starting point for a full day out; 5,000mAh makes more sense as a light backup.
- The recharge input deserves attention, too. Mine lists an older 5V input; USB-C input is worth looking for when choosing a newer model.
- My three phone charges are a reference point, not a promise for another phone. The number of charges depends on your phone.
My exact model is an older one, so below are current Anker options.

Things to know

- Start with capacity. Consider 10,000mAh for a full day out or 5,000mAh for a light backup. The number of phone charges depends on your phone.
- Choose magnetic charging or a cable. The magnetic picks cover iPhone 12–17 series, with model exclusions for the Nano 5K. Check compatibility before choosing.
- Check the recharge port. USB-C is the easiest starting point for a newer everyday power bank. The 313 accepts USB-C or Micro-USB input; the MagGo 10K lists USB-C input up to 30W.
- Consider the weight in your bag. The 313 weighs 7.5 oz, the MagGo 10K weighs 215.9 g (7.62 oz), and the Nano 5K weighs 122 g.
FAQ
How many phone charges will I get?
It depends on your phone. My PowerCore 10000 charges my phone about three times, and Anker says the 313 can charge a phone up to three times. Real-world usable capacity is lower than the rated mAh: Anker notes about 5,500–6,500mAh of usable capacity for the MagGo 10K after battery cell and circuit inefficiencies.
Can I take it on a plane?
TSA’s power-bank guidance says: “Portable chargers or power banks containing a lithium ion battery must be packed in carry-on bags.” Check your airline’s rules, too.
What's mAh vs Wh?
mAh describes battery capacity; Wh describes energy. My PowerCore 10000 label lists 10000mAh / 36Wh.
How we chose
I’ve personally owned and used the PowerCore 10000 (A1263) for about three years. The three current picks are based on official Anker specifications and prices checked October 10, 2026. We have not tested the three current models.
