Quick answer

Choose the UGREEN Nexode Air 45W if you mainly charge one phone or tablet at a time and want a compact, straightforward charger. Choose the UGREEN Nexode Air 100W 4-Port if you need to power multiple devices simultaneously, such as a laptop, phone, and accessories. The 45W is simpler and more portable; the 100W is more capable but larger.

What the 45W and 100W models actually offer

The UGREEN Nexode Air 45W Charger Space Gray delivers 45W of power through a compact design, making it suitable for fast charging compatible phones and tablets. It has a single charging output, so you plug in one device at a time. The Space Gray finish is a practical neutral that fits most bags and desks.

The UGREEN Nexode Air 100W 4-Port Charger provides 100W total across four ports, letting you charge up to four devices from one wall outlet. It uses the Nexode Air series design and is intended for phones, tablets, and other USB-powered devices. Because it has more ports and higher total output, it is physically larger than the 45W model.

Port count and power distribution: the real difference

The 45W charger is a single-device solution. If you plug in a phone, it can charge at up to 45W if the phone supports it; if you plug in a tablet, it will charge at the tablet's supported rate up to 45W. There is no sharing because there is only one port.

The 100W charger splits its total output across four ports. When you connect multiple devices, the charger distributes power among them, so a single device may not receive the full 100W if other ports are in use. The exact split depends on the devices and cables, but the key point is that total capacity is shared. This makes the 100W model better for simultaneous charging, while the 45W model is better for focused, single-device charging.

Size, travel, and everyday carry

The 45W charger is described as compact, which makes it easy to slip into a small bag or pocket. For travel where you only need to charge a phone or a tablet overnight, it takes up minimal space and adds little weight.

The 100W 4-port charger is larger because it houses more ports and higher-power components. It is better suited to a desk, a hotel room with multiple devices, or a travel bag where you have room for one charger that replaces several. If you frequently move between locations and want the lightest possible kit, the 45W is the more practical choice.

When a power bank makes more sense

If your main concern is charging away from a wall outlet, a power bank may be a better fit than either charger.

It is designed for travel and everyday carry when you cannot rely on a wall socket.

This power bank does not replace a wall charger for long sessions, but it complements either the 45W or 100W charger. For example, you could use the 45W charger at your destination and the power bank during transit. The built-in cable also means you do not need to pack a separate USB-C cable for the power bank itself.

Trade-offs to weigh

  • Portability vs. capability: The 45W charger is compact and easy to carry, but it charges only one device at a time. The 100W charger is larger but can power up to four devices simultaneously. If you carry a charger daily and rarely need multiple ports, the 45W wins on size.
  • Single-device speed vs. multi-device convenience: With one port, the 45W delivers its full output to that device. The 100W shares its total output across connected devices, so individual speeds drop when more ports are used. For one phone or tablet, the 45W is simpler. For a laptop plus phone plus earbuds, the 100W is more practical.
  • Wall charging vs. battery backup: Both chargers need a wall outlet. The Nexode Power Bank 20000mAh adds battery power for times when no outlet is available, but it is another item to carry and charge. If you often work away from outlets, consider adding the power bank rather than choosing a larger wall charger.
