It supports a wide range of USB-C devices including phones, tablets, and laptops, plus a dedicated trickle charging mode for low-power gadgets.

What Buyers Say

The 45W fast charging capability is frequently mentioned for its ability to quickly power up devices like the Samsung Galaxy S24 Ultra. However, some discussions on Reddit point out potential limitations with specific fast charging protocols like Samsung's Super Fast Charging 2.0 due to PPS amperage limits. The weight of 489g is a recurring point, balancing its high capacity with portability.
“Okay, so this thing charges my S24 Ultra crazy fast, like 50% in 20 minutes, and the built-in cable is a game changer, no more forgetting my cord! But man, it's a brick, definitely feels heavy in my bag. Still, worth it for the speed and not having to hunt for cables.”

Buying Guide
When buying a power bank, you need to think about how much power you actually need and how fast you want your devices to charge. A higher capacity (measured in mAh) means more recharges, but also more weight. The wattage (W) determines how quickly your phone or tablet will charge, and if it can even power a laptop. Don't just look at the biggest numbers; consider what devices you'll be charging most often.
Battery Capacity (mAh)
This tells you how much energy the power bank stores, like the size of a gas tank. A 20,000mAh power bank can typically charge a standard smartphone 3-5 times, or a tablet once or twice, before needing a recharge itself. More mAh means more charges, but also a heavier device.
Output Wattage (W)
This is how fast the power bank can deliver power to your device, similar to how quickly a gas pump fills your tank. A 45W output is fast enough for most modern smartphones and tablets, and can even provide a meaningful charge to smaller laptops. Lower wattage means slower charging.
Built-in Cable
Having a cable built right into the power bank means you never forget your charging cord. It's super convenient for travel and reduces clutter, but make sure the built-in cable type (like USB-C) matches your primary devices.
Alternatives
If this power bank's 45W output isn't enough for your laptop, look for models with 65W or 100W USB-C Power Delivery. If you need something lighter, consider power banks with 10,000mAh capacity or less.
