NOBIS A2651 35W Power Bank, 20,000mAh, 4 Ports with LED Display

For a day out with a phone, tablet and headphones, the NOBIS A2651 power bank gives you one portable place to top up several devices. Its 20,000mAh capacity and four charging ports make it practical for travel, commuting or sharing power while you’re away from a socket.

With 35W fast charging and USB-C input and output, it can recharge compatible devices and be recharged itself using the included USB-C to USB-C cable. The LED digital display shows the remaining charge at a glance, helping you decide when it’s time to recharge the power bank.

Two USB-A ports and two USB-C ports let you charge up to four devices at once. That’s a useful alternative to carrying a separate power bank for each device, particularly when you’re travelling with more than one essential.

What you’ll notice day to day

The capacity is suited to keeping everyday electronics going beyond a single top-up, while the compact dimensions of 13.7 x 7 x 2.6 centimetres make the unit straightforward to pack in a bag. It weighs 392 grams, so it offers a portable charging option with substantial capacity for phones, tablets and other compatible devices.

The four-port layout is handy when you need to charge several items together, whether that’s a phone and headphones on a commute or a mix of devices during a trip. Customer feedback often highlights charging speed, portability and the ability to recharge devices more than once. Experiences with reliability are mixed, and some customers find the power bank a little heavy.

Key points

The 35W output supports fast charging for compatible devices. The product information gives the example of an iPhone 15 reaching 60% in 30 minutes, actual charging depends on the device and its charging requirements. The two USB-C ports support both input and output, while the two USB-A ports add flexibility for connecting other devices. Supported device types include smartphones, laptops, tablets, smartwatches and headphones.

A trickle charging mode is available for smaller devices such as Bluetooth headphones and smartwatches. Double-tap the power button to activate it, a looping LED indicates that the mode is on. Built-in protections cover overcharging, over-voltage, over-current, short circuits and overheating, with automatic shut-off also listed among its features.

The package includes the power bank, a 30cm 3A USB-C to USB-C cable and an instruction manual. Its rechargeable lithium polymer battery and digital charge display make it a practical choice for keeping track of power and topping up compatible devices on the move.

Getting the most from it

Use the USB-C to USB-C cable for two-way charging: connect it to recharge the power bank or to charge a compatible device. When charging several items, connect them to the available ports according to their connectors. For headphones or a smartwatch, double-tap the power button to switch on trickle charging and look for the looping LED signal.

Final verdict

The NOBIS A2651 suits people who want one rechargeable power bank for a phone and other everyday devices, rather than a single-port option for just one item. Its 20,000mAh capacity, 35W fast charging, four-port design and clear LED display bring useful flexibility to travel, busy days out and shared charging.
