> Since the SE is so compact, I’d prefer something portable that isn't a total brick in my pocket, maybe around 5,000 to 10,000 mAh.

Dude, i feel u on the SE battery struggle. Honestly, the phone is great but it definitely dies way too fast. For your situation, I’ve been using the Anker 622 Magnetic Battery MagGo 5000mAh and it's basically perfect for the size. I know the SE 3rd gen doesnt have the magnetic ring built-in, but I just use a MagSafe-compatible case and it sticks right on. It supports that 20W fast charging you're looking for, and it doesnt get nearly as hot as some of the cheaper ones i've tried.

If you want more juice, Baseus Adaman2 30W 10000mAh Power Bank is super solid too. It's actually really tiny for a 10k pack, like seriously pocketable. Anyway, both work great with a standard Lightning to USB-C cable for the SE. No battery health issues so far on mine... so yeah, gl! 👍

Seconding the recommendation above. Honestly, I've had issues with the magnetic packs too—they get way too hot and the SE doesn't even have MagSafe anyway, so it's kinda pointless.

I've been using the Anker 523 Power Bank PowerCore Slim 10K PD for a couple years and it's basically the gold standard for value. It's super thin, fits behind the phone in one hand, and handles the 20W fast charging without getting scary hot. Plus, it's usually only like $30-35. If you want something even cheaper, the UGREEN 10000mAh Power Bank 20W PD is actually reallyyy solid too and often on sale. Just make sure you grab a good Anker 541 USB-C to Lightning Cable cuz the cable matters just as much for that fast charging speed.

TL;DR: Skip the magnetic stuff for the SE. Stick to a slim 10k mAh wired pack for the best balance of price and battery health.

Seconding the recommendation above. Honestly, the Anker 523 Power Bank PowerCore Slim 10K PD is a solid choice, but I've actually had some issues with heat on that one when I'm fast-charging in my pocket. Since ur worried about long-term battery health for that SE, you gotta be careful with the heat buildup... it's literally the worst enemy for those small batteries.

Jumping in here because I'm kinda obsessed with safety specs since I fried an old phone with a cheap brick once. If you want something that stays cool, check these out:

* Zendure SuperMini 10,000mAh Portable Power Bank - This thing is tiny (like a credit card!) and it's built like a tank. It has great thermal management so it doesn't get as hot as some of the cheaper ones.
* Nitecore NB10000 Gen 2 Ultra-Lightweight Carbon Fiber Energy Brick - Seriously, this is the lightest 10k pack I've ever used. It's super premium and actually used by hikers cuz it's so reliable.

Basically, just make sure you use a high-quality cable too! I've been using the Belkin BoostCharge USB-C to Lightning Cable (Braided) and it's been way more durable than the apple ones. Anyway, hope that helps you keep ur SE alive through the day! Have you noticed if it gets hot even when ur just using regular apps??

Quick question for ya before you drop money on a new pack—what's your actual battery health percentage in the settings right now?? If it’s already dipping low, even the best power bank is basically just a band-aid for a dying cell. I’m kinda new to the DIY repair scene but I’ve been messing with my own phones for years, so I always wonder if it’s worth just swapping the internal battery yourself instead of carrying a brick everywhere? It's a pretty straightforward project on the SE if you have the tools! But anyway, if you’re set on the power bank route, definitely keep these warnings in mind: * Avoid using those super cheap "fast charge" cables from random brands. Honestly, a bad cable will fry your SE’s charging chip way faster than a "cheap" power bank will. * Be careful with charging while the phone is tucked in your pocket. The SE is so small that it can't dissipate heat well, and high-speed charging in a tight space is a recipe for disaster tbh.
* Check your Lightning port for lint! If the connection isn't perfect, the 20W PD protocol might keep dropping back to slow charging, which makes the whole fast-charge bank feel like a waste of money.

Coming back to this... Phoenhaven is totally right about checking the health percentage first. If youre already down in the low 80s, you're basically just carrying around a portable life support system at that point. I do a lot of my own repairs and the one thing I gotta warn you about is fast-charging while the phone is under load. The SE is so tiny it basically acts like a little oven. If you're fast-charging at 20W while using maps or gaming, you're gonna cook that battery way faster than normal. I've seen so many SEs with screen lift because the battery bloated from heat stress. Also, if you do decide to swap the battery yourself, dont buy those sketchy no-name kits. They usually lack the proper thermal sensors and can get real dangerous when you hit them with high wattage. Its better to just be patient with the charging and keep it out of your pocket while it's topping up.
