The best power bank for iPhone 16 and recent Samsung Galaxy models is one with a USB-C PD port rated 20W or higher for wired charging, or a Qi2-certified wireless pad if you want cable-free charging  but the wireless story has an important catch for Galaxy owners: Samsung's S25 and S26 series support Qi2 speeds but have no built-in magnets, so they need a magnetic case to snap onto a MagSafe-style pad at all. This guide breaks down exact charging specs for both ecosystems and what that means for choosing a power bank like our Power Brick II, which pairs a 15W MagSafe-compatible wireless pad with wired USB-C PD.

Key Takeaways

• iPhone 16 and later reach 25W wireless charging on Qi2 25W (Qi2.2) certified chargers; every other Qi2 device, including all current Galaxy S25/S26 models, caps at 15W regardless of the charger's rating.

• Samsung Galaxy S25 and S26 phones support Qi2 charging speeds but have NO built-in magnets  you need a magnetic case for a MagSafe-style pad to align and snap into place at all.

• MagSafe is Apple's proprietary standard; Qi2 is the open, cross-platform standard that most Android flagships (Galaxy, Pixel, OnePlus) are adopting — they are similar but not identical, and "MagSafe compatible" doesn't always mean full Qi2 certification.

• For wired charging, USB-C PD at 20W+ covers fast charging on both current iPhones and Galaxy phones  Samsung's Super Fast Charging (25–45W) needs a compatible PD profile to hit its top speeds.

• A 15W wireless pad, like the one on Power Brick II, charges every current iPhone and Galaxy flagship at their actual achievable wireless speed  only iPhone 16+ owners are leaving speed on the table by not using a 25W-specific charger.

MagSafe vs Qi2 vs Qi2 25W: What's Actually Different

Three overlapping terms cause most of the confusion when shopping for a wireless power bank. Here's what each one actually means:

Qi2 was built on Apple's MagSafe magnetic alignment system (the "Magnetic Power Profile"), which is why the two are so often confused. The practical difference: MagSafe is Apple-exclusive and tops out at 25W on recent iPhones; Qi2 is the open, licensed standard that Samsung, Google and OnePlus are adopting, but the newer 25W tier (Qi2 25W, also called Qi2.2) is currently only reaching 25W on iPhone 16 and later — every other Qi2 device, Galaxy included, still caps at the original 15W ceiling no matter how fast the charger itself is rated.

iPhone Charging Specs by Model

Samsung Galaxy Charging Specs by Model

The detail most buying guides skip: the Galaxy S25 and S26 series support Qi2 wireless speeds but ship with no built-in magnets. Samsung calls this "Qi2 Ready" rather than full Qi2 — the phone can accept Qi2-speed power, but without a magnetic case, it won't snap into alignment on a MagSafe-style pad and may charge slowly or not at all if it drifts off-centre. If you own a recent Galaxy and want to use a magnetic wireless power bank, budget for a magnetic case alongside it  this isn't optional, it's a hardware gap Samsung's phones don't close on their own.

Wired Charging: The Simpler Half of the Story

Wired charging is far less fragmented than wireless. Both ecosystems have standardised on USB-C, and USB-C Power Delivery (PD) is the protocol that negotiates fast-charging speeds with compatible cables and power sources. A power bank with an 18–20W+ USB-C PD port fast-charges current iPhones effectively; Samsung's Super Fast Charging (25–45W depending on model) needs a PD profile that matches, but will still charge  just not at its absolute peak  from a standard PD source.

Both Power Brick I (18W USB-C PD) and Power Brick II (20W USB-C PD, dual ports) cover this comfortably for either ecosystem's daily fast-charging needs.

Which Power Bank Feature Actually Matters for Your Phone?

• iPhone 16 or later, want maximum wireless speed: look specifically for a Qi2 25W / Qi2.2-certified pad — a standard 15W Qi2 pad (like most on the market, including Power Brick II) still works, just not at the full 25W ceiline.

• iPhone 15 or earlier: 15W is your wireless ceiling regardless of charger  a 15W MagSafe-compatible pad gets you everything your phone can accept.

• Galaxy S25/S26: confirm you have a magnetic case before buying a magnetic wireless power bank — without one, the wireless pad won't align. Wired USB-C PD is the simpler, guaranteed option.

• Galaxy S24 or earlier: wireless speeds are lower across the board (10–15W) and magnetic alignment isn't part of the picture at all  a standard Qi pad or wired PD charging is the practical choice.

Frequently Asked Questions

Does the iPhone 16 charge faster wirelessly than the Galaxy S25?

Yes, on the right charger. iPhone 16 and later can reach 25W on a Qi2 25W (Qi2.2) certified pad. The Galaxy S25 series caps at 15W wirelessly regardless of the charger used, since Samsung hasn't adopted the faster Qi2.2 tier yet.

Does my Samsung Galaxy need a special case to use a MagSafe-style power bank?

Yes, if it's a Galaxy S25 or S26. These phones support Qi2 charging speeds but have no built-in magnets, so a magnetic case is required for the phone to align and snap onto a magnetic wireless pad. Without one, wireless charging may be slow or fail to align at all.

Is MagSafe the same as Qi2?

Similar but not identical. Qi2 was built using Apple's MagSafe magnetic alignment design, so the two are compatible in practice, but MagSafe is Apple's proprietary branded implementation while Qi2 is the open, licensed standard other manufacturers use. A charger can be "MagSafe compatible" as a marketing description without being formally Qi2-certified, so check for the actual certification if precision matters to you.

What wattage power bank do I need for fast wired charging?

18–20W USB-C PD covers fast charging on current iPhones. Samsung's Super Fast Charging tops out higher (25–45W depending on model), but a 20W PD power bank will still charge a Galaxy phone quickly, just not at its absolute peak rate.

Will a 15W wireless power bank work with any iPhone or Galaxy?

Yes  15W is the practical wireless ceiling for every device except iPhone 16 and later (which can reach 25W on a specifically Qi2 25W-certified pad). A 15W pad, like the one on Power Brick II, delivers the maximum achievable wireless speed for every Galaxy model and for iPhone 12–15.

Match the Spec to Your Actual Phone

Wireless charging speed depends on both the pad and the phone — buying a faster charger doesn't help if your phone's ceiling is lower, and Galaxy owners specifically need a magnetic case before a magnetic pad does anything at all. Our Power Brick II covers the practical middle ground: 15W MagSafe-compatible wireless plus 20W wired USB-C PD, matched to what iPhone 12–15 and every current Galaxy phone can actually use.

A Note on Our Previous iPhone Guide

Our earlier power bank guide for iPhone covered general capacity and USB-C PD basics. This guide goes further into device-specific wireless charging specs and the MagSafe/Qi2 landscape across both iPhone and Samsung Galaxy, including the Galaxy magnetic-case requirement that guide doesn't cover.
