Chargers & Powerbanks

Smartphone chargers and powerbanks for desk, travel and fleet use

The phone in the box ships without a charger now, but the user still needs one. Picking the right charger is about matching wattage to the phone, choosing the right number of ports for the desk, and deciding whether powerbanks belong in the bag.

What this category covers

Single-port USB-C (Universal Serial Bus Type-C) wall chargers from 20 W to 100 W, multi-port desk chargers with USB-C and USB-A combinations, GaN chargers for high wattage in compact size, MagSafe and Qi wireless charging pads and stands, USB-C car chargers, and powerbanks ranging from 5,000 mAh pocket sizes to 30,000 mAh travel capacities.

How to choose chargers and powerbanks

Match wattage to the phone's fast-charging spec

iPhone 15 fast charges at 27 W; Pixel 8 at 27 W; Galaxy S24 at 25 W; Galaxy S24 Ultra at 45 W. Fast-charging Android flagships from Chinese brands sometimes go to 100 W or more. Pick a charger that meets or slightly exceeds the phone's fast-charging spec; going much higher gives no extra speed.

Decide on single-port or multi-port

For travel, a single-port 30 W to 65 W charger covers a phone and lighter laptops. For desk use, a multi-port charger with two USB-C and one USB-A handles phone, tablet and laptop or earbuds simultaneously. Multi-port chargers split wattage across ports; check the per-port spec, not just the total.

Pick the right wireless standard

Qi works with most current phones at up to 15 W. MagSafe (iPhone) goes to 25 W with magnetic alignment. Newer Qi2 brings the magnetic alignment to Android. For fleet desks, wired charging is faster and more reliable; wireless is convenient but slower and warmer.

Size powerbanks for the actual need

5,000 mAh covers one phone charge in a pocket. 10,000 mAh covers two charges or one charge plus tablet topup. 20,000 mAh and above suit travel where outlets are scarce, but airline regulations cap at 27,000 mAh for cabin baggage on most carriers.

Key features to compare

GaN versus traditional chargers

Gallium Nitride (GaN) chargers are smaller and lighter than silicon-based chargers at the same wattage. For travel, GaN saves real space in the bag. For desk use, the size difference is less important.

Pass-through charging on powerbanks

Pass-through lets the powerbank charge devices while charging itself. This is useful for users who plug in once at night and want both their phone and powerbank ready in the morning, but it shortens the powerbank's battery life slightly.

Charging standards

Power Delivery (PD) is the universal fast-charging standard for USB-C. Quick Charge (QC) is Qualcomm's older standard, still common on Android. Most current chargers support both. Phone-specific protocols (Apple, Samsung Super Fast Charging) are usually compatible with PD or QC.

What to check before buying

• Phone's fast-charging wattage and supported standards?
• Single port for travel or multi-port for desk use?
• GaN size advantage worth the small premium for travel?
• Powerbank capacity matched to typical away-from-outlet duration?
• Cables included or sold separately, with the right wattage rating?

Frequently asked questions

Why does my new charger not fast-charge my phone?

The most common reasons are: charger wattage below the phone's fast-charge spec, cable not rated for the wattage, or the charger missing the phone's specific fast-charge protocol. Use a USB-C PD charger of the right wattage with a certified cable to cover most phones.

Are wireless chargers worth it?

For desk and bedside use, yes for convenience. They are slower than wired (15 W versus 27 W to 45 W on most phones), generate more heat (which slightly shortens battery life), and need the phone aligned correctly. For travel and primary charging, wired is still faster and more reliable.

Can I take a powerbank on a plane?

Yes in cabin baggage; powerbanks are not allowed in checked luggage. Most airlines cap capacity at 27,000 mAh (about 100 Wh). Higher capacity needs airline approval and is rarely allowed. Always carry powerbanks in cabin bags.

What is GaN and why does it matter?

GaN (Gallium Nitride) is a semiconductor material that is more efficient than silicon at high frequencies. GaN chargers run cooler and pack more wattage in less volume. A 65 W GaN charger is about half the size of a silicon-based 65 W charger. For travel, this is a meaningful difference.

How big a powerbank do I need for international travel?

10,000 mAh covers a phone for two days without outlet access. 20,000 mAh covers phone, tablet and noise-cancelling headphones together for a long flight. 27,000 mAh is the common airline limit and the maximum for high-capacity travel powerbanks. Pick based on actual device count and trip duration.
