The AsperX 165W Laptop Power Bank delivers up to 165 watts across three ports, including a retractable USB-C cable and a standard USB-A port. BigRobsVan highlighted the utility of the dedicated low-power mode for safely charging small accessories like earbuds. The TFT display provides detailed real-time stats, though at 1.47 pounds it is heavier than a typical phone charger. Additionally, the 65W maximum input limits recharge speed to nearly two hours, requiring users to plan ahead rather than expecting quick top-ups between meetings.

Full review
165W output across three ports
The AsperX 165W Laptop Power Bank divides its maximum power delivery across a trio of connection points. A top-mounted USB-C port provides up to 100 watts, while an adjacent USB-A port handles up to 30 watts for legacy devices. The third charging avenue is a retractable built-in USB-C cable that stores neatly along the bottom edge of the unit. This configuration allows users to power multiple gadgets simultaneously without hunting for loose cables in their bags.
The device can deliver 165 watts total when utilizing both USB-C ports together. In practical scenarios, this means a user can charge a high-performance laptop at full speed while simultaneously topping up a smartphone via the retractable cable or the standard USB-A port. The power distribution chip manages these loads intelligently to prevent overcharging smaller electronics.
Retractable 23-inch built-in cable
A standout physical feature is the retractable charging cable. This eliminates the common frustration of carrying separate wires and ensures that a compatible USB-C connection is always available right on the device. The cable retracts smoothly into its housing and stays secured by a magnetic catch when not in use.
BigRobsVan highlighted how this integrated solution saves time during daily commutes or vanlife adventures where digging through pockets for cables is inconvenient. The built-in cable supports up to 100 watts of output, making it robust enough to charge laptops directly without needing an external adapter. This convenience factor transforms the power bank from a simple battery into a consolidated charging hub.
TFT display tracks runtime and stats
The front of the unit features a bright TFT color screen that provides granular data about its current status. The primary view displays the remaining battery percentage alongside real-time output wattage, allowing users to monitor exactly how much power is being delivered to their devices at any given moment.
BigRobsVan confirmed that this interface is highly legible even in direct sunlight, a critical feature for outdoor users. The display also allows customization of brightness levels and screen timeout duration to conserve power when the unit is idle.
Aluminum unibody dissipates heat
Constructed from aviation-grade aluminum alloy, the chassis provides a premium feel while serving a functional thermal purpose. This improved cooling helps maintain consistent charging speeds and extends the lifespan of both the internal battery cells and the connected devices.
Small device mode protects earbuds
Charging low-power accessories like wireless earbuds or smartwatches often fails with standard power banks because they cannot detect a valid load and shut off prematurely. The AsperX addresses this with a dedicated small device mode that drops the output to approximately two watts.
BigRobsVan explained that holding the main button toggles this low-power state, indicated by a specific icon on the screen. This ensures that tiny gadgets receive enough current to charge safely without triggering the power bank's automatic shutoff protocols. While in this mode, users cannot simultaneously charge larger devices like laptops, representing a minor functional trade-off for the added protection.
65W input limits recharge speed
Despite its high output capabilities, the power bank accepts a maximum of 65 watts when recharging from a wall outlet. This bottleneck means that fully replenishing the 20,000mAh capacity takes nearly two hours using a compatible fast charger.
YouTube reviewer SamTalkOutdoors found that even when connected to a 140-watt wall adapter, the unit caps its input at around 65 watts. While this recharge time is respectable for a battery of this size, it requires planning ahead. Users relying on quick top-ups between meetings may find themselves waiting longer than expected compared to devices with higher bidirectional charging speeds.
1.47 lb weight affects portability
The robust aluminum construction and large battery cells result in a total weight of 1.47 pounds. This mass is noticeable when carrying the device for extended periods, particularly in jacket pockets or small messenger bags.
Strengths
- +Delivers up to 165W of total power across three ports, including a 100W USB-C port and a retractable built-in USB-C cable.
- +Features a bright TFT color display that shows real-time output wattage, battery percentage, and estimated remaining runtime.
- +Includes a dedicated low-power mode for safely charging small devices like earbuds without overcharging them.
- +Constructed with an aviation-grade aluminum unibody shell that provides premium durability and improved heat dissipation.
Watch-outs
- −Weighs approximately 1.47 lbs, noticeably more than a typical phone charger.
- −Accepts a maximum input of only 65W for recharging the power bank itself, taking nearly two hours to fully replenish the battery.
How it compares
The AsperX distinguishes itself with a durable aviation-grade aluminum unibody, offering better heat dissipation than the plastic housing of the Shargeek or the finish of the Anker Prime. Its 165W ceiling sits just below the Shargeek's 170W and well above the Anker A1383's 65W single-device limit, and like the A1383 it has a built-in USB-C cable.
