NOBIS 35W Power Bank 20000mAh with USB-C fast charging, 4 ports and LED display (Green)

The essentials

A portable charger is only useful if it keeps up with your day, not if you have to baby it. This NOBIS Power Bank is positioned as a higher-output option thanks to 35W fast charging and support for PD 3.0 and QC 4.0 protocols. On paper, it’s meant to quickly top up modern phones and other power-hungry devices, and it also covers multi-device charging with 4 external ports.

The big appeal here is the mix of speed, shared charging, and practical control. There’s also an LED digital display, plus a trickle charging mode for smaller gadgets—useful when you don’t want to run everything at full power.

Key features that matter in real use

The 35W fast charging angle is the headline. It’s paired with PD 3.0 and QC 4.0 support, which should help the power bank negotiate sensible charging speeds with compatible devices. The listed examples give you an idea of its intent: it claims fast top-ups such as moving a Phone 16 from 0 to 61% and S22 Ultra from 0 to 40.9% in 30 minutes (with the usual “results vary” caveat that’s standard for marketing claims).

Another practical plus is the charging setup. The power bank offers 2 USB-A outputs and 2 Type-C ports, with the note that the Type-C ports support input and output. In everyday terms, that can mean fewer compromises—plug in a phone on one port, a tablet on another, or share power without having to pick which device gets the “one available slot”.

Charging performance: fast, but check your expectations

The packet pushes fast charging in a way that suits people who are regularly away from sockets: commuting, travel days, long workdays, or weekends where you’re using your phone heavily. It’s not just for phones either, the description claims it’s compatible with laptops as well as phones and other gadgets.

Still, it’s worth being realistic. A power bank can only charge as fast as the device (and the charging protocol it supports) allows. If your device doesn’t respond to the higher-speed protocols, the “35W” headline may feel less exciting than expected.

Bi-directional charging and multi-port convenience

One thing you don’t always get with portable chargers is easy “power for the power bank”. This model includes an included C to C cable and is described as bi-directional fast charging: it can charge itself in about 3 hours, and it claims charging Phone 16 in about 2 hours (again, subject to device and conditions).

For day-to-day use, the multi-port design is the difference between “my phone is fine, but the headphones will have to wait” and a calmer morning. You can top up several devices at once, which is handy for households, travel groups, or simply when you’ve got more than one thing that needs juice.

Trickle charging for small gadgets

Not everything wants high power. The power bank has a trickle charging mode, activated by double-tapping the power button and indicated by a looping LED light. The description mentions this as a way to efficiently charge standard devices while extending battery life for smaller gadgets, with examples like Bluetooth headphones and smartwatches.

This is a sensible feature if you often travel with wearables or low-power accessories. Where it can be a bit limiting is that trickle mode is about protection and longevity for smaller devices, so it won’t feel like a fast “fix” for something that urgently needs a big charge.

Safety and portability considerations

The safety side is covered on paper with protection features mentioned for over-charge, over-voltage, over-current, short-circuit and overheat. The description also states it’s airline approved, which matters if you travel and want a charger you can take with you without a lot of stress.

However, without details like weight, exact battery tech, or charging cable specifications beyond “C to C cable included”, you’ll want to sanity-check whether it matches your bag space and how you plan to charge it at home or on the move.

What’s included and what to double-check before buying

You’ll get a C to C cable according to the description, and the rest of your charging “setup” will depend on what cables you already own. Since the pack supports multiple outputs, it’s also worth thinking about how you typically charge: - If you mostly use USB-C devices, the two Type-C ports should keep things flexible. - If you have older accessories that need USB-A, the two USB-A ports are there for you.

Also, because the description lists compatibility with specific phone lines, it’s a good idea to confirm that any laptop or other device you want to charge supports the relevant charging behaviour you’re expecting. Otherwise you may not see the same speed claims.

When it makes sense

This NOBIS Power Bank is a strong “grab-and-go” pick if you need fast charging capacity (35W), want to top up multiple devices at once, and like having a clear LED digital display. It makes sense for people who are away from power points often, travel regularly, or manage more than one gadget per day.

It might not be a great match if you only charge one low-power device occasionally—then a simpler, lower-output power bank could be more than enough. You may want to skip it if you’re expecting every device to hit the fastest speeds regardless of charging protocol support.

Buying verdict

Is it worth it?

It’s worth considering if you want a higher-output portable charger that can handle multi-device charging (2 USB-A + 2 Type-C) and adds trickle charging for smaller accessories, with safety protections and airline approval mentioned. The “fast charging” positioning will matter most if your devices are compatible with PD 3.0 / QC 4.0-style behaviour.

You might look elsewhere if your use is very basic and you don’t benefit from 4-port convenience, or if you only care about charging one device and don’t want to carry a more feature-rich (and likely bulkier) option.

Quick questions people usually ask

Does it charge multiple devices at the same time?

Yes—it's described with 4 external output ports (2 USB-A and 2 Type-C ports), allowing up to 4 devices to charge simultaneously.

What is the trickle charging mode for?

It’s designed for smaller gadgets and is activated by double-tapping the power button. It’s indicated by a looping LED light.

Is it suitable for travel?

It’s stated to be airline approved, which is useful if you want a portable charger for trips.

Will it charge laptops?

The description claims compatibility with laptops, but it’s still wise to check that your specific laptop supports the charging behaviour you expect.
