Product Overview

The sharge Retractable 165 Power Bank is a high-capacity portable charging solution designed for users who need serious power on the go. With a total output of 165W and a built-in retractable cable, this 20000mAh power bank aims to eliminate the hassle of carrying multiple chargers and cables while providing enough juice to charge laptops, smartphones, and tablets simultaneously.

What sets this power bank apart is its integrated 100W retractable USB-C cable—a feature that addresses one of the most common frustrations with portable chargers: tangled or forgotten cables. Combined with an additional USB-C port and a USB-A port, this device offers versatile charging options for multiple devices at once.

The unit features a smart digital display that shows real-time power status, percentage, and temperature readings, giving users clear visibility into their charging situation. With its 74Wh capacity, it stays within airline safety limits, making it a practical companion for frequent travelers.

Key Features and Benefits

165W Total Power Output

The sharge power bank delivers up to 165W of combined output across its three charging ports. This high wattage means you can charge power-hungry devices like laptops alongside your smartphone and tablet without experiencing slow charging speeds. The distribution allows for efficient multi-device charging, which is particularly useful during long travel days or when working remotely from locations without easy outlet access.

Built-in 100W Retractable Cable

The integrated retractable USB-C cable is arguably the standout feature. Rated at 100W, this cable can handle fast charging for most modern laptops and smartphones. The retractable mechanism keeps the cable neat and prevents the tangling issues that plague traditional portable chargers. Simply pull the cable to your desired length and press the button to retract it back into the housing when finished.

This design eliminates the need to remember to pack charging cables separately, reducing the number of items you need to carry.

20000mAh Capacity (74Wh)

With 20000mAh of capacity, this power bank offers substantial charging capability. According to the manufacturer’s claims, it can fully charge an iPhone 17 approximately three times or provide one full charge to a laptop. The 74Wh rating keeps it under the 100Wh limit imposed by most airlines, meaning you can carry it in your carry-on luggage without issues.

For context, this capacity should provide roughly:

• 3+ charges for most modern smartphones
• 1-1.5 charges for tablets
• 1 full charge for ultrabooks and smaller laptops
• Partial charge for larger, power-hungry laptops

Smart Digital Display

The built-in screen displays three key metrics: remaining power percentage, current output wattage, and internal temperature. This real-time information helps you make informed decisions about when to recharge the power bank and monitor whether your devices are charging at optimal speeds. The temperature display is particularly useful for safety monitoring during high-power charging sessions.

EV-Grade Battery Cells

The power bank uses what the manufacturer describes as “EV-grade” battery cells, suggesting higher quality and safety standards similar to those used in electric vehicles. These cells are rated for over 500 full charge cycles while maintaining battery health, which should translate to several years of regular use before noticeable capacity degradation occurs.

Multiple Charging Ports

Beyond the built-in cable, you get:

• 1 additional USB-C port (output specifications not publicly detailed)
• 1 USB-A port for legacy devices

This three-port setup means you can charge your laptop via the retractable cable while simultaneously charging your phone and wireless earbuds through the other ports.

Pros and Cons

Pros

• High power output: 165W total is sufficient for charging laptops and multiple devices simultaneously
• Built-in retractable cable: Eliminates cable management headaches and reduces what you need to pack
• Airline-safe capacity: 74Wh rating allows you to take it on flights without issues
• Smart display: Real-time information helps you monitor charging status and battery health
• Multi-device charging: Three ports enable simultaneous charging of different devices
• Durable battery cells: 500+ cycle rating suggests long-term reliability
• Premium design: Gradient aesthetic makes it visually appealing compared to generic power banks

Cons

• Size and weight: 20000mAh capacity with high-power components likely means this is not a pocket-friendly device
• Limited port specifications: The exact output ratings for individual ports beyond the 165W total are not clearly specified
• Retractable cable durability: Mechanical retraction systems can be potential failure points with heavy use
• Single cable type: The built-in cable is USB-C only, which may not suit all devices
• Price point: High-capacity, high-power banks with integrated cables typically command premium pricing (specific pricing not provided)
• Recharge time: Information about how long it takes to fully recharge the power bank itself is not publicly available

Who This Product Is Best For

The sharge Retractable 165 Power Bank is ideal for:

• Business travelers: Those who need to keep laptops and phones charged during long flights or airport layovers
• Digital nomads: Remote workers who frequently change locations and need reliable power backup
• Content creators: Photographers, videographers, and creators who use power-hungry equipment in the field
• Students: Those spending long hours in libraries or studying in locations without convenient outlet access
• Tech enthusiasts: Users with multiple devices who want a single charging solution that can handle everything
• Minimalist packers: Travelers who want to reduce cable clutter and consolidate their charging gear

This power bank makes the most sense if you regularly charge laptops on the go and value the convenience of not carrying separate cables.

Who Should Avoid It

This power bank may not be the right choice for:

• Budget-conscious buyers: High-capacity, high-power banks with integrated cables typically cost more than basic alternatives
• Ultra-light travelers: If you only need to charge a smartphone occasionally, a smaller, lighter power bank would be more practical
• Users without USB-C devices: The built-in cable is USB-C, so if your primary devices use other connection types, you won’t benefit from the main feature
• Those needing extreme durability: If you work in harsh environments, the retractable mechanism and digital display may be more vulnerable than simpler designs
• Users wanting the smallest possible footprint: 20000mAh capacity means this will be bulkier than lower-capacity options

Comparison Insight

In the high-capacity power bank market, most competing products offer either high wattage output or built-in cables, but rarely both. Traditional 20000mAh power banks typically max out at 65W-100W total output and require you to bring your own cables.

The integrated retractable cable is a differentiating feature that directly competes with products from brands like Anker, RAVPower, and Baseus. However, many competitors in this capacity range don’t offer retractable cables, instead providing fixed cables or no cables at all.

The 165W total output puts this in the upper tier of portable chargers. Most standard power banks top out at 60W-100W, making this a better choice for users with multiple high-power devices. The smart display is becoming more common but is still not universal in this product category.

Compared to carrying a laptop charger plus a separate power bank, this solution consolidates your charging setup, though it may not fully replace a dedicated laptop charger for extended work sessions.

Frequently Asked Questions

Can this power bank charge a MacBook Pro?

Based on the 100W retractable cable and 165W total output, this power bank should be capable of charging most MacBook Pro models. However, the largest MacBook Pro models with maximum power draw may charge more slowly than with their original chargers. Specific compatibility details are not publicly available from the manufacturer.

How many times can it charge my phone?

The manufacturer claims approximately 3 full charges for an iPhone 17. For other smartphones, the number of charges will vary based on battery capacity, but most modern phones (with 3000-5000mAh batteries) should get 2-4 full charges from this 20000mAh power bank, accounting for conversion losses.

Is this allowed on airplanes?

Yes. At 74Wh, this power bank falls under the 100Wh limit set by most airlines for carry-on luggage. However, it must be carried in your carry-on bag, not checked luggage, as is standard for all lithium-ion battery devices.

How long does it take to recharge the power bank itself?

This information is not publicly available from the manufacturer. Recharge time typically depends on the input wattage you use. With a high-wattage USB-C charger (65W or higher), you can expect significantly faster recharge times than with a standard 20W phone charger.

What happens if the retractable cable breaks?

Retractable mechanisms can be potential failure points. If the cable fails, you would still have the two other ports (USB-C and USB-A) available for charging. Warranty and repair information should be verified with the manufacturer or seller before purchase.

Can I charge three devices at full speed simultaneously?

The total output is 165W distributed across all ports. While you can charge three devices at once, the power will be shared among them. Specific power distribution details for each port configuration are not publicly available.

Does it support pass-through charging?

Information about pass-through charging (charging the power bank while it charges other devices) is not publicly available. This feature varies by manufacturer and model.

In Conclusion

The sharge Retractable 165 Power Bank represents a thoughtful approach to portable charging, addressing real pain points that frequent travelers and multi-device users face. The integrated 100W retractable cable is genuinely useful, eliminating the “did I pack my cable?” anxiety and reducing cable clutter in your bag.

With 165W total output and 20000mAh capacity, this power bank delivers substantial charging capability for laptops, tablets, and smartphones. The smart display adds transparency to the charging process, and the airline-safe capacity means you can take it anywhere.

The main considerations are size and weight—inevitable with this capacity—and the durability of the retractable mechanism over time. The lack of detailed specifications for individual port outputs and recharge times is also worth noting.

For users who regularly charge laptops away from outlets and want to minimize what they carry, this power bank offers a compelling combination of power and convenience. The built-in cable alone may justify the investment for those who value simplicity and hate managing multiple cables.
