Key Features & Benefits

• 25000mAh High Capacity: Provides enough power to fully charge a MacBook Pro 16″ once, an iPhone 15 approximately 4-5 times, or keep an iPad Pro running through multiple workdays, which means you can work remotely all day without searching for wall outlets.
• 145W Maximum Power Output: Delivers up to 100W from a single USB-C port or distributes power intelligently across multiple ports, so you can fast-charge demanding laptops like MacBook Pro, Dell XPS, or gaming laptops while simultaneously charging phones and tablets.
• 100W Fast Recharging: Fully recharges the power bank itself in approximately 1.5 hours using a 100W USB-C PD charger, which means you can top up during lunch breaks or short hotel stays instead of leaving it plugged in overnight like traditional power banks.
• Smart TFT Display: Shows real-time voltage, current, power output, and remaining battery percentage with precise accuracy, so you know exactly how much charge remains and can monitor charging speeds to verify your devices are receiving optimal power.
• Three-Port Simultaneous Charging: Supports charging three devices at once through two USB-C ports and one USB-A port with intelligent power distribution, eliminating the need to prioritize which device charges first during busy workdays or travel.

Use Cases & Applications

For Students: University students can power MacBook Air or Dell XPS laptops through entire study sessions at libraries or coffee shops without competing for limited wall outlets. The 25000mAh capacity provides approximately 8-12 hours of laptop use depending on workload, ensuring you can complete assignments, attend virtual classes, and take online exams without battery anxiety. The simultaneous charging capability means you can keep your laptop, phone, and tablet charged during marathon study sessions before finals. Computer science students running power-intensive development environments or simulations benefit from the 100W output that maintains laptop performance under load.

For Business Travel: Remote professionals and consultants traveling between client sites can work productively on flights, trains, or in airport lounges without searching for outlets. The under-100Wh capacity meets airline carry-on requirements for all commercial flights worldwide. Sales representatives conducting back-to-back client presentations can keep their laptop and presentation remote charged throughout the day. The TFT display provides peace of mind by showing exactly how much power remains before important meetings.

For Remote Work & Fieldwork: Journalists, photographers, and videographers working on location can power laptops for editing, charge camera batteries, and keep phones operational during all-day shoots. Researchers conducting field studies can run laptops, tablets, and measurement equipment without generator access. Construction managers reviewing plans on tablets at job sites benefit from reliable power throughout workdays. The durable aluminum construction withstands the rigors of outdoor and industrial environments.

For Content Creation: Video editors working remotely can run power-hungry laptops while transferring footage from cameras and portable SSDs. Photographers on multi-day shoots can recharge multiple camera batteries, power laptops for image culling, and keep phones charged for client communication. Live streamers attending conventions or events can maintain equipment power through extended streaming sessions without seeking venue power access.

For Emergency Preparedness: The PB205 serves as backup power during outages, providing multiple phone charges for emergency communication and enough capacity to power laptops for work or entertainment. The fast recharging means you can quickly top up when power becomes available between outages. Families can charge multiple devices simultaneously during weather emergencies or natural disasters.

For Gaming On-The-Go: Mobile gamers using Nintendo Switch, Steam Deck, or ROG Ally benefit from extended play sessions—the power bank provides 2-3 full charges for these devices. The 100W output can even power gaming laptops during travel, though at reduced performance compared to wall outlets. Esports competitors traveling to tournaments can ensure their equipment remains charged during long event days.

For Digital Nomad Lifestyle: Remote workers hopping between cafes, co-working spaces, and accommodations can maintain productivity without outlet dependency. The power bank eliminates anxiety about finding seating near outlets or managing limited charging time in crowded spaces. Digital nomads working across time zones can charge devices during overnight travels on buses or trains.

The UGREEN PB205 delivers exceptional capacity and power output for demanding mobile computing scenarios. However, understand that the 25000mAh rating (at 3.6V) translates to approximately 90Wh of actual output—when charging a laptop requiring 20V, the capacity effectively becomes around 4500mAh at that voltage due to conversion losses. This means expecting exactly 25000mAh of usable power at all voltages is unrealistic; actual device charges depend on your device’s voltage requirements and the power bank’s conversion efficiency.

The 145W maximum output applies only when using all three ports simultaneously with specific power distribution—single-port maximum remains 100W (USB-C) or 22.5W (USB-A). Check your laptop’s power requirements before purchasing; while 100W charges most laptops, some high-performance gaming laptops or mobile workstations require 130W+ and may charge slowly or not maintain charge under heavy use with this power bank.

For fastest recharging of the power bank itself, invest in a dedicated 100W USB-C PD wall charger—using lower-wattage chargers extends recharge time proportionally. The included cable is rated for 60W, so replace it with a 100W-rated cable if you have a 100W charger for optimal recharge speeds. The power bank can charge devices while being recharged itself (pass-through charging), though this generates additional heat and slightly reduces efficiency.

The TFT display drains minimal power but remains active during charging—this is normal behavior and the small power consumption doesn’t significantly impact capacity. The aluminum housing conducts heat well, and the power bank may feel warm during high-power output or fast recharging—this is expected behavior, though ensure adequate ventilation and avoid using on soft surfaces that trap heat.

Battery capacity naturally degrades over time and charge cycles—expect approximately 80% of original capacity after 500 full charge cycles (roughly 1-2 years of regular use). To maximize lifespan, avoid completely depleting the battery regularly and store at 40-60% charge if not using for extended periods. The under-100Wh rating ensures compliance with airline regulations, but always verify your specific airline’s policies before travel as regulations occasionally change.
