Best portable chargers for iPhone 16 Pro Max?

Question

Upgrading from my 12 Pro Max because the battery life is basically toast now. I really need something reliable for the 16 Pro Max since I'm constantly out shooting video and the power drain is real. My budget is around $80. I've looked at the Anker 737, but man, that thing is huge—I need something pocketable. Also saw some mixed reviews on the magnetic ones regarding heat issues during fast charging. Is there a sweet spot between capacity and size that won't overheat the phone? Or should I just suck it up and go with a smaller MagSafe pack and deal with slower speeds? What’s the best move here?

TL;DR: Skip the magnetic stuff for video work. The heat dissipation on the 16 Pro Max while filming is already borderline; adding a MagSafe brick just throttles your sensor. Grab the Anker Nano Power Bank 10000mAh 30W instead. Oh man, this is exactly my thing. I obsess over these power curves. I’ve tested the Baseus Blade 100W 20000mAh versus the Sharge Flow 2 10000mAh 40W, and honestly, for a 16 Pro Max, you want output stability over flashy magnets. If you're shooting 4K ProRes, the phone pulls a ton of juice and the magnetic mounts just don't dissipate heat well enough. You end up with a phone that hits thermal limits in ten minutes. The Nano 30W is lowkey the best move because it stays cool, fits in a coin pocket, and maintains a consistent 30W charge which is the sweet spot for the 16 series before it starts getting spicy. If you really want that magnetic convenience, only use it when the phone is idle, never while the camera app is open. Anyway, bottom line is, keep the cable in the loop for video sessions. It’s way more efficient and keeps your internal battery from dying early from that constant heat soak. Grab a short, braided USB-C to USB-C cable and thank me later.

Rarely post but had to chime in—grab the Anker MagGo Power Bank 10K. It's the perfect size, fits in any pocket, and avoids the overheating mess of cheaper magnetic chargers.

Everyone pushes the latest MagSafe bricks, but honestly, you need to be careful with heat saturation. Fast charging a 16 Pro Max while shooting video is a recipe for battery degradation.

How long are your typical video sessions?

Do you need to charge while actively filming, or can you wait for breaks? Before you buy, confirm if your camera rig setup allows for cabled charging, as magnets often fail under heavy thermal load.
