UGREEN PB770 300W 48000mAh Portable Power Bank
The UGREEN PB770 is an extreme-capacity, heavy-duty portable power station engineered to run demanding multi-device setups, outdoor expeditions, and emergency home backups. Packing an enormous 48,000mAh capacity (153.6Wh) and pushing a massive 300W of total simultaneous output, it utilizes premium, ultra-safe LiFePO4 battery cells designed to last for years.
With its 140W PD 3.1 ultra-fast bidirectional charging and integrated emergency lighting matrix, this powerhouse delivers reliable off-grid energy wherever you need it.
Key Features
Delivers a monumental combined power output of 300W across its 5-port matrix (3 USB-C and 2 USB-A), allowing you to rapid-charge multiple laptops, tablets, and flagship smartphones simultaneously without power throttling.
The premium USB-C1 port features advanced PD 3.1 technology, delivering up to 140W of output to high-drain workstations like the MacBook Pro. This same port supports 140W high-velocity input, recharging the entire massive 48,000mAh reservoir from empty to full in an incredibly fast 1.5 hours.
Built with automotive-grade Lithium Iron Phosphate (LiFePO4) chemistry, providing exceptional thermal stability and safety. It boasts a long lifespan of over 3,000 recharge cycles before dropping to 80% capacity — offering up to 6x the longevity of standard lithium-ion banks.
Houses a heavy-duty 153.6Wh power core. It can fully recharge an iPhone over 10 times, power a MacBook Air 15-inch 1.1 times, or run portable electronics for days during camping trips or blackouts.
Features a built-in multi-mode LED ambient light strip on the chassis. It switches easily between High, Low, and an emergency SOS strobe mode, making it an essential companion for night camping or unexpected power outages.
Outfitted with an interactive LED display that delivers real-time power metrics, highlighting remaining battery percentage, current input/output wattages, and the active fast-charging protocols being utilized.
