Thunderobot's new V20 Pro brings high-wattage laptop charging to a compact 20,000mAh form factor. Launched in China and listed on JD.com at an aggressive price of 289 yuan (about $40), the V20 Pro targets users who need reliable, multi-device power on the go — from ultrabooks and gaming laptops to phones, tablets, and wearables.
Key specifications and hardware highlights
Battery and output
The V20 Pro packs a 20,000mAh battery and supports a combined maximum output of 165W. That power is split across a 2C + 1A port configuration: two USB-C ports and one USB-A port. Both the built-in USB-C cable and the USB-C port support up to 100W via PPS, while the USB-A port offers up to 30W. Thanks to this arrangement, the power bank can feed two laptops simultaneously or quickly top up one laptop plus accessories.
Built-in retractable cable and input speed
Thunderobot includes a 60cm retractable USB-C cable integrated into the chassis for instant use and tidy storage. The V20 Pro also supports 65W input for fast self-charging, letting users replenish the power bank much faster than older, slower models — a useful feature before flights or meetings.
Smart display and always-on status
A bright TFT color display on the front shows remaining battery percentage, current power output by port, and charging status in real time. The screen can operate in an always-on mode so users can monitor power flow at a glance during heavy charging sessions.
Thermal design and cell longevity
Thunderobot uses AI-assisted temperature control to manage heat during high-wattage operation alongside an aluminum-alloy chassis for efficient dissipation. Internally the V20 Pro relies on automotive-grade 21700 lithium cells, rated for more than 5,000 charge cycles while retaining over 80% of their original capacity — a key selling point for long-term reliability.
Safety and accessory modes
The device includes multiple hardware and firmware protections: over-voltage, over-current, short-circuit, and temperature control systems, and it carries official 3C certification. A low-current mode is provided for charging delicate accessories like smartwatches and Bluetooth earbuds safely.
Design, dimensions and portability
The V20 Pro has a minimalist aesthetic with a deep-space grey aluminum body. It measures roughly 156.05 × 52.8 × 40.8 mm and weighs about 517 g — compact enough to fit in a backpack or laptop bag while offering higher output than many similarly sized rivals.
How it compares to competitors and market relevance
Compared with other 20,000mAh laptop power banks, the V20 Pro stands out for peak 165W output, integrated retractable cable convenience, and a color TFT readout. Many competing models emphasize either high output or portability; Thunderobot aims to balance both while adding AI-driven temperature management and long-life 21700 cells.
The product launch arrives as the portable charging market shifts toward higher wattages, GaN chargers, and Qi2.2 wireless standards. For example, Baseus recently updated its PicoGo lineup with compact GaN chargers and Qi2.2-enabled accessories, illustrating the broader trend toward faster, smarter charging ecosystems. In that context, the V20 Pro's combination of high wired output and a low price positions it competitively for domestic and potentially international buyers.
Use cases and advantages
- Remote work and hybrid offices: fast laptop top-ups during long meetings or remote sessions.
- Travel and field work: quick recharge of one or two laptops plus phones without carrying multiple chargers.
- Content creators and photographers: reliable, high-current output to power cameras, laptops, and lighting gear.
- Emergency backup: high-capacity reserve for power outages or long transits.
Advantages include dual-laptop charging, fast 65W recharge, long cycle life with 21700 cells, built-in cable convenience, and a clear, always-on display for monitoring.
Bottom line
Thunderobot's V20 Pro is a compelling budget-friendly option for professionals and power users who need laptop-grade output from a portable power bank. With 165W peak output, a smart TFT display, AI thermal control, and durable 21700 cells, it packs features usually found in pricier units — all at a highly competitive price point on JD.com.
