UGREEN 300 W Power Bank, 48000 mAh/153.6Wh (25286)

Overview

The UGREEN 25286 is a 48,000 mAh (153.6 Wh) power bank built to run laptops, tablets, phones and cameras through long trips, outdoor work and power cuts. Five USB outputs share up to 300 W, and the main USB-C port both delivers and accepts 140 W. It is a tabletop unit with a carry handle and an area light, not a pocket battery, and at 153.6 Wh it cannot travel on a passenger aircraft.

Is it right for you?

• Suits a 14 or 16-inch MacBook Pro, MacBook Air or USB-C Windows laptop, plus iPads, iPhone 15 to 17, Galaxy and other Android phones, Steam Deck, ROG Ally, Nintendo Switch, cameras and drones through their USB chargers.
• Suits a desk, vehicle or work base where it stays put; it weighs 1637 g.
• Not for laptops that charge only through a barrel pin without a USB-C PD input.
• No AC socket, so it cannot run fans, kettles or TVs, and it is not an uninterruptible power supply (UPS) or inverter.
• No wireless (Qi) charging.
• Not for air travel: 153.6 Wh is above the 100 Wh limit in current IATA power bank guidance, and this is not something an airline can approve.

Key features

• 48,000 mAh, 153.6 Wh, in automotive-grade lithium iron phosphate (LiFePO4) cells rated to keep more than 80% capacity after 3,000 cycles.
• Up to 300 W total across five outputs.
• USB-C1: up to 140 W out or 140 W in, PD 3.1 with 28 V 5 A and PPS 3.3 to 21 V at 5 A.
• USB-C2 and USB-C3: up to 100 W each with PPS 3.3 to 21 V at 5 A.
• USB-A1 and USB-A2: up to 22.5 W each with QC 3.0, AFC, SCP and Apple 5 V 2.4 A modes.
• Smart LED display and a three-mode LED area light with bright, low and SOS settings.
• Carry handle, non-slip base; 143 × 105 × 77 mm.
• Protection against over-voltage, over-current, over-charge, over-discharge, short circuit and over-temperature.
• About 2 charges for a 13-inch MacBook Air or 14-inch USB-C laptop, about 4 for an iPad Air, about 8 for a smartphone, about 7 for a Nintendo Switch or a mirrorless camera battery, or around 12 hours for a 10 W Wi-Fi router.

What else you need

A 140 W USB-C PD 3.1 charger for the fastest recharge, and a cable rated for 28 V 5 A on the 140 W path. The 240 W USB-C to USB-C cable in the box covers the main port; USB-A devices need their own cables.

Before you buy

• Do not take this power bank on a passenger aircraft, in cabin or checked baggage. For shipment, ask the carrier about regulated lithium battery cargo procedures.
• Only USB-C1 delivers 140 W. The nameplate maximum is not guaranteed to every device or every port at once, and the usable output is lower than the cell rating because of conversion losses.
• No 140 W wall charger is in the box.
• Devices negotiate their own charging profile; phones with proprietary fast-charge modes fall back to a shared standard. Cable rating and the device’s input decide the speed, not the operating system.
• Keep it upright on a stable, dry, ventilated surface. Do not use it in rain, standing water, a hot parked vehicle or direct sun. Carry it by the handle with a supporting grip and never hang other loads from it.
• Stop using it if any connector, cable, enclosure or plug is bent, cracked, loose, swollen, scorched or unusually hot. Keep ports dry and free of lint or metal; never probe them with metal. Do not modify, splice, crush or knot cables.
• The area light is not a road flare or certified safety beacon.
• It does not replace the maker’s own charger for firmware updates, recovery or safety-critical use.
• Dispose of it through an authorised battery or e-waste channel, never in fire or mixed waste.
