About Ugreen

Ugreen designs practical charging and connectivity gear—USB-C GaN chargers, power banks, cables, and hubs—that aims to work reliably with today’s phones, tablets, handheld consoles, and laptops. The focus is on standards-based fast charging (USB-C Power Delivery, PPS, Quick Charge) and durable construction that holds up to daily use.

When to Choose Ugreen

• You want a single compact charger for phone, tablet, and ultrabook.
• You need a flight-safe power bank to keep a phone or laptop running during travel.
• You’re adding ports (HDMI, USB-A, SD) to a USB-C laptop and want a simple, driver-free hub.
• You prefer clearly labeled wattage/capacity and cables that match your charging or data needs.

Chargers: Pick the Right Wattage

Match the charger’s total wattage to your device’s maximum input. If a charger has multiple ports, power is shared—actual output per port can drop when several devices are connected.

Charger wattage	Best for	Examples
20–30W (single-port)	Phones, small tablets, earbuds	iPhone fast charge (20W), iPad mini
45–67W (dual-port available)	Ultrabooks, iPads, handheld consoles	MacBook Air, iPad Pro, Steam Deck
100–140W (multi-port)	Multi-device setups or larger notebooks	MacBook Pro 14/16, USB-C Windows laptops

• GaN advantage: GaN chargers are smaller and run cooler than older silicon designs at the same wattage.
• Standards to look for: USB-C PD 3.0/3.1, PPS for Samsung fast charge, and backward compatibility with QC where relevant.
• Scenario tip: For travel, a 45–65W dual-port GaN charger often covers a phone + ultrabook without carrying two bricks.

Power Banks: Capacity and Flight Rules

Capacity is rated in mAh but airlines use Wh. Most routes allow up to 100Wh in carry-on; many 20,000–26,800mAh banks are below this limit.

Capacity class	Typical Wh	Use cases	Approx. phone recharges
10,000mAh	~37Wh	Day trips, commuters	2–3 (3,000–4,500mAh phones)
20,000mAh	~74Wh	Weekend travel	4–6
26,800mAh	~99Wh	Long flights, light laptop top-ups	6–8

• Laptop top-ups: Look for USB-C PD output (e.g., 30–65W). Expect stabilization, not full-speed charging on power-hungry models.
• Faster phone charging: Choose banks with PD and PPS if your phone supports it (e.g., many Samsung Galaxy models).

How to convert mAh to Wh

Wh ≈ (mAh × 3.7) ÷ 1000. Example: 20,000mAh ≈ 74Wh (carry-on friendly under 100Wh).

Cables: Match Power and Speed

• Charging wattage: For 60–100W charging, use an e‑marked USB-C cable. For 140–240W (PD 3.1 EPR), ensure the cable is rated for 240W.
• Data speed:
  • USB 2.0: 480 Mbps (fine for charging, basic data).
  • USB 3.2 Gen 1/2: 5–10 Gbps (external SSDs, 4K video capture).
  • USB4/Thunderbolt 3/4: up to 40 Gbps (high-speed storage, displays).
• Video over USB-C: Requires DisplayPort Alt Mode support from your laptop/phone and a capable cable or hub.

Hubs & Docks: Compatibility Notes

• Displays: Many compact hubs provide 4K/30; 4K/60 typically needs DP 1.4 bandwidth and a hub that specifies 4K/60.
• Host support: Video output needs USB-C DP Alt Mode. Some systems support only one external display without DisplayLink drivers.
• Power passthrough: If a hub offers 85–100W PD passthrough, use a charger with equal or higher wattage for best results.

Quick Setup and Safety Tips

• Use a charger that meets or exceeds your device’s rated input; the device will draw only what it needs.
• For multi-port chargers, plug higher-draw devices (laptop/tablet) into the primary USB-C port.
• Keep power banks between ~20% and 80% when stored to extend lifespan; recharge every 2–3 months if unused.
• Avoid extreme heat; do not cover chargers while in use.
• Clean USB ports with dry compressed air to remove dust.

FAQ

Will a Ugreen USB-C charger fast charge my iPhone or Android?

Yes. iPhones fast charge with USB-C PD (20W+). Many Android phones support PD and PPS; a PD/PPS charger will negotiate the best available speed.

What charger do I need for a Steam Deck or Nintendo Switch?

Steam Deck uses up to 45W via USB-C PD—choose a 45–65W charger. Nintendo Switch handheld charging is up to ~18W; a 30W or higher PD charger works well.

Can I charge a laptop and phone at the same time?

Yes on multi-port models, but total wattage is shared. Example: a 65W charger might allocate 45W to a laptop and 20W to a phone. Check the port map on the product page.

Are Ugreen power banks allowed on flights?

Most models up to 100Wh (e.g., 10,000–26,800mAh) are carry-on approved by most airlines. Always pack in carry-on and confirm airline rules before travel.

Which cable should I use for a 100W laptop?

Use an e‑marked USB-C cable rated for 100W or higher. For 140–240W laptops, use a 240W (EPR) USB-C cable.
