Introduction – Why the CUKTECH 10 Mini Matters.

The portable power bank market is absolutely saturated. You can barely scroll through Amazon without being bombarded by endless identical-looking black slabs claiming astronomical charging speeds, questionable capacities, and frankly, dubious build quality.
So when CUKTECH entered the market promising a tiny 10,000mAh power bank capable of delivering up to 55W fast charging, it immediately caught my attention. That’s laptop-grade power in something not much larger than a packet of tissues. Big claims, small package — always an intriguing combination.
Even more interesting is the price. At roughly £25–£30 in the UK, the CUKTECH 10 Mini is significantly cheaper than many well-known brand competitors, while still offering:

Living With the CUKTECH 10 Mini

After several weeks of daily usage, a few things stand out:

Good Points :

• Ultra-compact form factor
• Excellent charging speeds
• Brilliant LED display
• Reliable thermal performance
• Fantastic value

Bad Points:

• Slightly chunky thickness
• USB-A still present (I’d prefer all USB-C)
• Display brightness could be a little higher
• None of these are deal-breakers.

Who Is This For?

The CUKTECH 10 Mini is ideal for:

• Daily commuters
• Business travellers
• Students
• Digital nomads
• Mobile gamers
• Anyone tired of slow charging power banks
• If you carry multiple devices and want serious power in your pocket, this should be on your shortlist.

Over the past few weeks, I’ve been using the CUKTECH 10 Mini as my daily carry power bank, throwing it into coat pockets, laptop bags, and backpacks, using it to charge smartphones, earbuds, tablets, handheld gaming consoles, and even laptops.
This review focuses heavily on real-world usage, comfort, build quality, charging performance, and overall value — the stuff that actually matters when you’re relying on a power bank day in, day out.

Design & Build Quality – Small, Solid, and Purposeful.

Let’s start with the first thing you notice: just how compact this thing really is.
CUKTECH claims the 10 Mini is roughly the size of a pack of tissues — and surprisingly, that’s not far off. It’s short, chunky, and dense, designed to prioritise pocketability rather than ultra-thin aesthetics.

Materials & Construction

The outer shell is made from matte-finished plastic, but don’t let that put you off. This is good quality plastic — thick, solid, and reassuringly rigid. There’s no flex, no creaking, and no sense of fragility. It feels robust enough to survive being tossed into a bag full of keys, cables, and other assorted tech junk.

Fit and finish are excellent:

• Tight seams
• Flush ports
• Clean LED screen integration

Everything feels deliberate and well engineered. This is not a cheap-feeling power bank.

Comfort & Ergonomics

Here’s where the CUKTECH 10 Mini really shines. Because of its short, thick design, it sits extremely comfortably in the hand. It feels balanced and secure, with no awkward protrusions or strange weight distribution. In daily use, this matters more than you might expect — especially if you’re charging while holding your phone.
Unlike long, slab-style power banks that dangle awkwardly from a cable, the 10 Mini sits neatly behind the phone, making one-handed use genuinely possible.
In pockets, it’s equally impressive. Despite packing a full 10,000mAh battery and 55W charging hardware, it easily fits into:

• Coat pockets
• Hoodie pockets
• Backpack side pouches
• Tech organiser cases

This is genuinely a grab-and-go power bank — small enough that you’ll actually carry it daily, which is ultimately the entire point.

Port Layout & Display – Practical Done Right

The port layout is refreshingly sensible:

2 × USB-C ports
1 × USB-A port

This gives excellent flexibility for charging multiple devices or supporting older cables.

LED Digital Display

One of my favourite features is the LED digital display. Instead of vague four-dot battery indicators, you get:
Exact battery percentage
Real-time charging wattage
Input and output information

This is hugely useful in real-world usage. You instantly know:

How fast your phone is charging
Whether fast charging protocols are engaged
How much power remains

Once you get used to this level of feedback, it’s very hard to go back to dumb indicator lights.

Comfort & Daily Portability – One of the Best I’ve Used

Power banks often fail at one critical thing: being easy to carry. The CUKTECH 10 Mini absolutely nails it. At roughly 218g, it’s light enough to forget about but heavy enough to feel premium. There’s no sense of flimsiness, yet it never becomes a burden in a jacket pocket.
For commuters, travellers, and daily city users, this is ideal. I found myself naturally reaching for it every time I left the house — which is perhaps the highest praise you can give any accessory.

Charging Performance – The Real Star of the Show

Now let’s get to the most important part of any power bank review — charging performance (your “sound results”). This is where the CUKTECH 10 Mini seriously punches above its weight.
Maximum Output – 55W Fast Charging

Both USB-C ports support up to 55W output, which is frankly astonishing for a device this small.
In real-world testing, that translates to:

• iPhone 15 Pro Max → ~58% in 30 minutes
• Samsung Galaxy S25 Ultra → ~70% in 30 minutes
• Xiaomi 15 → ~87% in 30 minutes
• iPad Air → ~50% in 35 minutes
• Steam Deck → playable charging speeds.

Laptop Charging – Yes, Really One of the biggest surprises is its ability to charge laptops.

While you won’t be gaming on a MacBook Pro while charging, it can absolutely:

Top up ultrabooks
Sustain light productivity workloads
Emergency-charge larger laptops

For a power bank this small, that’s remarkable.

Charging Stability – Sustained Power Without Throttling

What separates good power banks from great ones is charging stability. Many cheap models advertise high wattage but throttle heavily once they heat up. The CUKTECH 10 Mini, however, shows excellent sustained output behaviour.

Real-world tests show:
Consistent 45–55W output
No aggressive throttling
Stable thermal performance

Even when charging high-draw devices like Xiaomi flagships, the power output remains stable across the entire charge cycle

This is a huge deal — especially for laptop and tablet users.

Efficiency & Real Capacity – Honest Performance.

Although rated at 10,000mAh, usable real-world capacity sits at around 70–75% efficiency, which is completely normal once voltage conversion losses are accounted for.

In daily usage, this translates to:

~1.8 full iPhone charges
~1.6 Galaxy S-series charges
~1.3 iPad Air charges

Heat Management & Safety

Despite delivering high power, thermal control is excellent. Even during sustained high-watt charging:

Surface temperature remains comfortable
No alarming heat build-up
No performance throttling

CUKTECH uses automotive-grade battery cells combined with a 9-layer safety protection system, covering:

Over-voltage
Over-current
Over-temperature
Short-circuit protection

This is reassuring, particularly when using such high wattages in a compact enclosure

Price & Value – One of the Best Deals in Portable Power

Here’s where the CUKTECH 10 Mini truly dominates. At £24.99–£29.99 in the UK, it undercuts most reputable competitors by a significant margin while offering:

• Higher wattage
• Smaller size
• Digital display
• Better charging protocol support

Comparable products from Anker, Baseus, UGREEN, or Belkin often cost £45–£70 for similar performance.

In pure value terms, this is exceptional.

Final Verdict – A Benchmark Pocket Power Bank
The CUKTECH 10 Mini genuinely redefines what we should expect from a compact power bank.
It combines:

• Outstanding charging performance
• Excellent comfort and portability
• Impressive build quality
• Ridiculously good pricing
• All in one tiny package.

This is not just good value — it’s market-disrupting value.
If you’re shopping for a 10,000mAh power bank in 2026, this deserves to be right at the top of your list.
