Ive tried a lot of these over the years and honestly, safety should be your biggest concern when you're buying something that literally stores energy in your pocket. In my experience, going with a reputable brand is worth the extra five or ten bucks because the cheap ones can actually damage your phones internal battery or just stop working when it gets cold or hot outside. Since you're confused about the numbers, basically 10,000mAh is the sweet spot for a day of heavy sightseeing. It means it holds enough juice to charge your iPhone 13 about two full times. For your budget, I always recommend the Anker 523 Power Bank PowerCore Slim 10K 10000mAh. Its thin enough to slide behind your phone in a pocket and Anker uses much better safety chips than the random brands you see on Amazon. If you want something even simpler that doesnt require a cable, look at the Anker 621 Magnetic Battery MagGo 5000mAh. It just snaps onto the back of your phone using magnets. It has less capacity (only about one full charge), but there's no cord to mess with while you're walking around. Just keep in mind that maps and photos drain the battery super fast, so I'd probably go with the 10K Slim just to be safe. Better to have too much power than not enough when you're lost in Manhattan...

> My budget is like $40. Sorry if this is a really dumb question but what is the best portable charger I should buy for an iPhone? I was in the same boat last year before a big trip. I ended up getting the Anker Nano Power Bank 5000mAh with Built-in Lightning Connector and it works so well. Honestly, no complaints at all since it fits right in my pocket without needing extra cables. Im super happy with it. Let me know if you want more recommendations!

Just saw this. Honestly, ive been burned so many times by those cheap generic chargers. It is super frustrating when they stop working after two days. Couple things to watch out for:

• fake mAh numbers that never actually charge your phone fully
• bulky designs that are a nightmare for pockets
• ports that break instantly Try looking for something with at least 18W output. Anything lower is gonna take forever.

^ This. Also, safety is absolutely paramount when you are navigating a busy city like NYC! I have spent a lot of time testing different units and the reliability of a solid brand makes a massive difference for peace of mind. I honestly love the INIU Power Bank 10000mAh Portable Charger because it is incredibly slim and fits right into a jacket pocket without any bulk. It is fantastic for sightseeing and honestly amazing for the price! Quick tips for the trip:

• Start charging once your phone hits 30 percent to manage heat better and stay efficient.
• Keep your charging cable looped loosely in your pocket to avoid internal wire damage while you are walking. This specific unit is super cost-effective and has been totally reliable for me over dozens of long travel days. You are gonna have an amazing time in the city!
