Pros

  • The integrated USB-C cable withstands over 10,000 bends, offering durability and convenient storage without needing an extra cable.
  • It delivers a total of 87W across three ports, allowing simultaneous fast charging for multiple devices.
  • A single USB-C port or the built-in cable can output up to 65W, capable of charging a 14-inch MacBook Pro to 50% in under 40 minutes.
  • The 20,000mAh capacity is approved for airline travel, providing extended use for devices like phones and tablets.
  • It recharges fully in 1.5 hours when using a 65W charger, minimizing downtime.
  • Includes one built-in USB-C cable, one additional USB-C port, and one USB-A port for broad device compatibility.

Cons

  • The advertised 87W is a shared total output, with a single port maximum of 65W, which can be misleading for users expecting 87W from one port.
  • Actual usable capacity for devices is estimated between 11,000mAh to 14,000mAh due to energy loss in conversion, not the full 20,000mAh.
  • The power bank weighs 15.5 oz (428g) and measures 6.2 × 2.9 × 1.0 inches, making it heavier and larger than some lower-capacity options.
  • Some users reported the power bank stopping discharge at around 30% charge when under max load, potentially due to heat management.
  • The built-in cable is relatively short, which might limit device placement during charging.

Dimension Scores

Charging Speed8/10

It provides up to 65W from a single port and can recharge an iPhone 15 Pro to 58% or a MacBook Air to 52% in 30 minutes, with the power bank itself recharging in 1.5 hours with a 65W charger.

Build Quality7/10

The integrated USB-C cable is designed to withstand over 10,000 bends, and user feedback indicates a well-built product with securely attached components.

Compatibility9/10

With two USB-C ports (one built-in cable) and one USB-A port, it supports a broad range of devices including MacBooks, iPhones, Samsung, and Switch, covering most modern electronics.

Portability6/10

Weighing 15.5 oz (428g) and measuring 6.2 × 2.9 × 1.0 inches, it's not the most compact, but the built-in cable reduces the need for extra accessories, making it reasonable for a 20,000mAh capacity.

Best For

  • Travelers needing to charge a MacBook Air to 52% in 30 minutes or an iPhone 15 Pro to 58% in 30 minutes on the go.
  • Users who need to power multiple devices simultaneously, such as a laptop, phone, and Nintendo Switch, with up to 87W total output.
  • Individuals requiring a power bank approved for airline travel with a 20,000mAh capacity.
  • Anyone looking for a power bank that can recharge itself quickly, achieving a full charge in 1.5 hours with a 65W charger.

Not Recommended For

  • Users who need a single port to deliver more than 65W for very power-hungry laptops.
  • Those prioritizing the absolute lightest and smallest power bank for minimal everyday carry, as it weighs 15.5 oz.
  • Individuals expecting the full 20,000mAh to be delivered to devices, as conversion loss reduces usable capacity to 11,000-14,000mAh.

Watch Out For

  • The 87W maximum output is distributed across three ports; a single device will only receive up to 65W, not the full 87W.
  • Despite the 20,000mAh rating, the actual power delivered to devices is closer to 11,000mAh to 14,000mAh due to energy conversion losses.
  • Some users experienced the power bank ceasing to discharge at around 30% remaining capacity when under heavy load, potentially indicating thermal throttling.
  • The built-in USB-C cable, while convenient, is short, which can be restrictive depending on where you place your devices.

What Buyers Say

Many users are stoked about the built-in USB-C cable, calling it a game-changer for travel because it means one less thing to pack and untangle. However, there's some confusion around the '87W' claim, with people realizing it's a total output, not per-port, and the single port maxes out at 65W. The actual usable capacity is also a recurring point, as the 20,000mAh doesn't fully translate to device charging due to energy loss. Despite these nuances, the fast recharge time for the power bank itself is a definite win for many.

“Okay, so the built-in cable is a lifesaver, seriously, no more digging for cords in my bag! But yeah, the 87W thing is a little sneaky, my laptop only pulls 65W from it, which is still fast, but not what I thought. Still, it charges my iPhone 15 like crazy and recharges itself super quick, so I'm keeping it.”

Common Praise

  • The built-in USB-C cable is incredibly convenient for travel, eliminating the need to carry an extra cable.
  • Charges MacBooks and other laptops quickly, with a single port delivering up to 65W.
  • The power bank recharges itself very fast, reaching full capacity in about 1.5 hours with a 65W charger.
  • Its 20,000mAh capacity provides multiple charges for phones and can top up laptops significantly.
  • The build quality feels sturdy, and the integrated cable mechanism is secure.

Common Complaints

  • The '87W Max Fast Charging' is a combined output, not what a single device receives, which is limited to 65W.
  • The actual power delivered to devices is less than 20,000mAh, typically 11,000-14,000mAh, due to energy conversion.
  • Some users experienced the power bank shutting down or stopping discharge at around 30% remaining charge under high load.
  • The built-in cable is short, which can be inconvenient if you need more slack between the power bank and your device.
  • It's not the lightest or smallest power bank for its capacity, weighing 15.5 oz.

Ownership Tips

  • After a few weeks, the built-in cable still snaps securely into place and hasn't shown any signs of wear.
  • The power bank's display, which only shows percentage, is basic but effective for checking remaining charge.
  • It gets noticeably warm when charging a laptop at 65W for an extended period, but not alarmingly hot.
  • The 1.5-hour recharge time is a huge benefit, making it easy to keep topped up between uses.
  • The weight, while not featherlight, feels balanced for its capacity and doesn't feel like a brick in a backpack.

Frequently Asked Questions

What is the maximum output for a single device?

A single device connected to either a USB-C port or the built-in USB-C cable can receive up to 65W of power. The 87W rating is the total output shared across all three ports.

How long does it take to recharge the power bank?

The power bank can be fully recharged in approximately 1.5 hours when using a 65W wall charger.

Is this power bank approved for airline travel?

Yes, the 20,000mAh capacity is within most airline regulations for carry-on luggage.

What devices can I charge with this power bank?

It's compatible with a wide range of devices, including MacBooks, iPhone 15 series, Samsung phones, Nintendo Switch, and other laptops and smartphones.

What is the actual usable capacity for charging devices?

Due to energy conversion losses, the effective usable capacity for charging devices is typically between 11,000mAh and 14,000mAh, not the full 20,000mAh.

Buying Guide

When you're looking at power banks, don't just fixate on the big mAh number. That's the raw capacity, but you lose some of that power when it converts to charge your devices. Also, check the 'W' (wattage) for both output and input. High output wattage means faster charging for your gadgets, especially laptops, and high input wattage means the power bank itself recharges faster. Pay attention to how many ports it has and what types (USB-C, USB-A) to match your devices.

battery_capacity (20,000mAh)

This number tells you how much energy the power bank can store. Think of it like the size of a gas tank. A 20,000mAh tank can fill up your phone's smaller tank multiple times, or give a bigger device like a laptop a significant boost, but remember some 'gas' is lost in transfer.

watts (87W Max Fast Charging)

Wattage is how fast power can flow. Imagine it as the width of the hose filling your device. 87W total means it can push a lot of power quickly, but it's shared. A 65W single-port output is still a wide hose, fast enough for many laptops, unlike slower 10-20W chargers that are only good for phones.

connector (Built-In C Cable + 1C1A)

This describes the types and number of 'hoses' available. A built-in USB-C cable means one less thing to carry, which is super convenient. Having additional USB-C and USB-A ports lets you charge different types of devices simultaneously, like a new iPhone (USB-C) and an older accessory (USB-A).

Alternatives

If this power bank doesn't quite fit, look for models with higher single-port wattage (e.g., 100W or more) for demanding laptops, or smaller mAh capacities (e.g., 10,000mAh) if extreme lightness is your priority.
