Best Phone Chargers for Every Device: iPhone, Android, Tablets & More

As covered in the companion guide to USB-C and fast charging, USB Power Delivery (PD) is the standard that lets a charger and a device negotiate voltage and current automatically, rather than the charger pushing out one fixed amount of power. That negotiation is what makes a universal charger possible — but it doesn't make every device's ceiling the same. Each manufacturer sets its own maximum accepted wattage, based on battery size, internal circuitry, and heat tolerance, and documents that ceiling separately. A charger rated well above a device's ceiling won't push it past that ceiling; the device simply requests less than the charger could technically supply.

That's why two phones plugged into the identical charger and cable can charge at very different speeds: the bottleneck is usually the device's own accepted wattage, not the charger. Knowing your specific device's documented ceiling — not a generic "fast charging" label — is the only reliable way to know what charger you actually need.

Every charger label lists wattage, and often voltage and amperage too. Wattage equals voltage multiplied by amperage — a charger listed as "5V⎓3A" delivers 15 watts, and one listed as "9V⎓3A" delivers 27 watts, even though the amperage figure looks similar in both. This is why two chargers can show a similar amperage number yet charge at very different speeds: the voltage side matters just as much, and USB PD negotiation is what lets a single charger offer several voltage-and-amperage combinations depending on which device is plugged in.

A charger's printed wattage is normally its maximum combined output, not a guarantee any single connected device will draw that full amount. A phone that only accepts 20W will request 20W from a 65W-rated charger and nothing more.

iPhone's own charging documentation lays out wattage recommendations by model generation, and they've shifted across hardware cycles. Devices from iPhone 15 onward use a USB-C cable directly; earlier models require a USB-C to Lightning cable. Any third-party adapter must support USB Power Delivery for fast charging to engage at all — a USB-A charger without PD support will still charge the phone, just far more slowly.

Android doesn't have one single fast-charging number the way iPhone's table does, because each phone maker documents its own requirements separately, and several run proprietary fast-charging features on top of standard USB PD. Pixel's own support documentation recommends a USB PD adapter rated for 15W or greater for most Pixel phones, and separately lists 30W, 45W, and 67W PD chargers as options for faster charging on models that support it. Newer flagship and foldable Pixel models are documented as supporting 30W or greater. A PD adapter with Programmable Power Supply (PPS) rated for 30W or more is what actually unlocks the faster tiers — a standard, non-PPS PD charger will still charge these phones, just not at their fastest documented rate.

Certain Galaxy models take a similar approach under a proprietary two-tier feature commonly referred to as Super Fast Charging, according to independent technical reporting. The lower tier delivers around 25W and is the more widely supported tier, including some foldables capped there by size and heat constraints. The higher tier, around 45W, is documented as available only on select flagship models. Reaching either tier requires a PD charger with PPS support — a standard PD-only charger without PPS reportedly caps out noticeably lower, around 18W. Independently reported charging-time data also suggests the real-world difference between the two tiers on the same phone can be modest — on the order of several minutes over a full charge.

Tablets sit in a wider wattage band than phones because screen size, battery capacity, and intended use vary so much within the category. As a general reference point rather than a per-model guarantee, tablets commonly charge somewhere between roughly 20W on the smaller end and up to 67W on larger, higher-capacity models — a range wide enough that a charger sized correctly for a phone may charge a tablet noticeably more slowly, simply because the tablet is built to accept more power than a phone-oriented charger is rated to supply.

The same USB PD negotiation that governs phone charging governs tablet charging too, so a single well-rated USB-C PD charger can typically serve both a phone and a tablet without issue — the tablet draws more power from the same charger, up to its own documented ceiling, and the charger adjusts automatically.

The honest answer is that a single good USB-C PD charger genuinely can serve an iPhone, an Android phone, and a tablet, because PD negotiation is designed for exactly this kind of mixed-device use — the charger doesn't need to "know" what brand of device it's plugged into, only what that device requests during negotiation. What determines whether one charger truly covers everything you own is whether it's rated at or above your single most demanding device's documented ceiling, and whether it includes PPS if any of your devices need PPS to reach their fastest documented tier.

The cable matters just as much here as the charger itself, and this is where mixed-device households most often lose speed without realizing it. Any cable rated above 60W needs an e-marker chip to carry that power, and a cable without one silently caps the connection at 60W regardless of what the charger and device could otherwise do.
