ZDNET’s lab-backed tests show the Cuktech 10,000mAh wireless bank is a standout cheap pick for earbuds and compact speakers.

Hook: Sick of dead earbuds and slow chargers on the go?

If you frequently scramble for a cable, get disappointed by a half-charged Bluetooth speaker at the gym, or struggle to compare spec sheets between dozens of bargain power banks — you're not alone. The market exploded in 2024–2026 with more cheap 10,000mAh options than ever, and it’s become harder to separate the junk from the few true value leaders. That’s why ZDNET’s hands-on testing and lab-style review of the Cuktech 10,000mAh wireless power bank matters: it gives real-world data, not just specs on a box.

TL;DR — Why ZDNET called it their "favorite cheap pick"

In ZDNET’s independent lab and real-world checks, the Cuktech 10,000mAh wireless bank consistently delivered practical performance far above its price class. The headline conclusions:

Solid real-world capacity: Usable output roughly in line with other 10,000mAh banks after conversion losses — good enough for many daily scenarios.
Wireless for earbuds and small speakers: The Qi pad is reliable for topping up earbud cases and compact Bluetooth speakers, even if it’s not a fast 15W puck.
Decent wired speeds and recharge time: Supports reasonable wired charging for phones and recharges in a practical window, unlike some ultra-cheap rivals that take forever.
Remarkable value: For the money, ZDNET found it outpaced pricier, similarly specced options when you weigh performance vs price.

ZDNET’s testing methodology — why you should trust these results

ZDNET follows a repeatable mixture of lab measurements and everyday use cases. Their process includes:

Measuring delivered mAh to a phone using controlled discharge tests (to capture conversion and voltage-step losses).
Timing wired and wireless charge sessions (to capture real watts delivered).
Simultaneous-device charging tests to see how the bank handles load sharing.
Multiple real-world scenarios: commuting, gym sessions, travel days, and extended outdoor use with Bluetooth speakers.
Safety and temperature checks to make sure a cheap price doesn’t trade away protection.

Key lab findings and what they mean for earbuds and speakers

Usable capacity: expect conversion losses — but not a surprise

The marketing number 10,000mAh is a battery-cell rating at the bank’s internal voltage. Once you boost to a phone or speaker’s 5V USB output, conversion losses occur. ZDNET’s practical takeaway mirrors industry norms: expect roughly 60–75% usable energy under realistic conditions. That means the Cuktech typically supplies the energy equivalent of about 6,000–7,500mAh to your devices during phone-style discharge tests.

Why that matters: earbuds use small amounts of energy. An earbud charging case (typical consumer cases in 2026) often sits in the 300–600mAh range, so a 10,000mAh bank with real-world efficiency can still deliver dozens of top-ups for earbud cases and several full charges for small Bluetooth speakers.

Wireless charging: reliable, but conservative wattage

ZDNET’s wireless pad tests confirm the Cuktech’s Qi surface works dependably. It’s not designed to compete with high-end 15W or 20W wireless power banks that prioritize phone fast charging; instead, it favors compatibility and convenience.

Best fit: earbud cases (Apple, Samsung, and other Qi-compatible cases) and compact speakers that support wireless charging or accept wireless-top-ups via placement on the pad.
Typical wireless speed: modest — ideal for topping up a case between meetings or during a commute, but not for a rapid phone refill.

Bottom line: If your main goal is fast phone wireless charging, pricier banks give higher wattage. If your goal is a cheap, dependable wireless pad for earbuds and occasional speaker top-ups, Cuktech hits the sweet spot.

Wired charging and recharge times

ZDNET measured the wired output and recharge behavior and found the Cuktech offers practical wired performance for everyday users:

Wired output: Good enough for a phone or a larger speaker when you need faster fill rates than wireless.
Bank recharge: Recharges in a reasonable timeframe on a modern USB-C charger (the bank accepts typical 18W–20W input in this price class). That means you’re not waiting half a day to top the bank back up.

That combination is important: many cheap banks are unreliable on either output or input; the Cuktech balances both for everyday convenience.

Real-world use cases — how this performs for actual people

ZDNET didn’t just run numbers — they used the bank in common real-world routines and reported practical performance for buyers like you.

Commute and daily carry (earbuds + phone)

If you commute with wireless earbuds in a case and a midrange smartphone, this is where the Cuktech shines. Example outcomes from ZDNET’s use-cases:

Earbuds: Multiple case top-ups across a week of commuting. Because earbud cases only need small energy pockets, the wireless pad or a wired plug will keep you covered.
Phone top-ups: One good boost to a drained phone — often enough to get through a transit day or extend battery life until you can plug in at a desk.

Gym and short outdoor sessions (speaker + earbuds)

For gym-goers who carry a compact Bluetooth speaker and Bluetooth earbuds, ZDNET found the Cuktech handled simultaneous loads reasonably well. You can charge earbuds wirelessly while topping a phone or small speaker via wired output — handy when you want music and a long workout without power worries.

Weekend travel or festivals (power efficiency matters)

When space and weight matter, a 10,000mAh bank is a practical compromise. ZDNET notes the Cuktech is light enough for daypacks and offers enough grunt to keep essential audio gear and a phone going through a weekend — especially when you prioritize small-case earbuds and compact speakers. For longer outdoor trips, consider pairing with compact solar charging kits to extend runtime at camps, festivals and remote sites (see compact solar kits).

How it compares to pricier options — where it wins and where it yields

Value is relative. ZDNET’s side-by-side comparisons highlight clear tradeoffs versus premium banks.

Advantages over pricier rivals

Price-to-performance: Delivers most of the day-to-day capability buyers need for a fraction of the cost. That’s ZDNET’s primary praise: smart utility without premium frills.
Simplicity: Fewer features means fewer points of failure — the wireless pad, a sensible mix of ports, and a predictable recharge window make it easy to use.
Size and weight: Compact 10,000mAh format is easier to carry than heavier 20,000mAh premium banks.

Where premium banks still beat it

Absolute charging speed: High-end banks often offer higher wired PD output (30W–100W) and faster wireless charging (10–15W+). If you need to fast-charge laptops or the newest flagship phones wirelessly, those premium banks win.
Efficiency and cycles: Higher-quality cells and GaN-enabled designs in premium models retain slightly more usable capacity and often last more charge cycles.
Advanced features: OLED charge readouts, multi-device intelligent power allocation, stronger magnetic alignment for MagSafe/Qi2 devices — those extras appear in higher price brackets.

ZDNET’s verdict: for the target buyer looking for a cheap, portable, wireless-ready bank primarily for earbuds, phones, and compact speakers, the Cuktech delivers better dollar-for-dollar practical performance than many costlier rivals that include bells and whistles most users don’t need.

Practical numbers — real charge estimates (useful rules of thumb)

ZDNET’s testing supports these conservative, practical estimates you can rely on when planning:

Earbud cases (typical 300–600mAh): Expect many — often 10–25+ top-ups depending on case capacity and conversion efficiency. That’s why a 10,000mAh bank is overkill for earbuds alone.
Small Bluetooth speakers (1,000–3,000mAh): Expect 2–8 full charges depending on speaker size. Small clip-style speakers may see multiple full charges; jam-focused portable speakers with larger cells will get fewer.
Smartphones (3,000–5,000mAh): Expect roughly 1–1.5 full phone charges in real-world use from a 10,000mAh bank after conversion losses.

These estimates are intentionally broad — battery chemistry, device efficiency, and charging overhead vary. ZDNET’s real tests reflect that spread and give confidence these are practical numbers, not just marketing math.

Safety, reliability, and quality checks

Cheap price tags can mask safety issues. ZDNET’s review runs through these practical checks, and the Cuktech passed the basics:

Temperature control: No excessive heat in typical use — an important sign for battery longevity and device safety.
Overcurrent and short protections: Present and functional in ZDNET’s tests.
Basic compliance: Check packaging for regulatory marks (CE, FCC, etc.) and retailer reputation. ZDNET still recommends buying from reliable stores to ensure authentic units and warranty support.

2026 considerations: trends that affect your purchase decision

Fast forward to 2026, and a few established trends change how we evaluate value power banks like the Cuktech:

USB-C ubiquity: With universal USB-C adoption largely complete by 2025, compatibility is better than ever. Make sure the bank offers USB-C ports for both input and output to stay future-proof.
Qi2 and magnetic alignment: The Qi2/magnetic standard improved wireless alignment and efficiency for phones and cases with MagSafe-style magnets. The Cuktech’s non-magnetic pad is fine for earbuds and casual wireless top-ups, but buyers wanting precise MagSafe alignment should consider Qi2-compatible units — see our notes on audio+visual setups and accessory alignment.
Regulatory and sustainability pushes: More emphasis on battery recycling and longer-lasting cells. Value buyers should still check warranty and return policies in case of early failure.

Actionable buying checklist — what to look for when you shop

Use this quick checklist (informed by ZDNET’s lab-style testing) to pick the right cheap power bank for earbuds and speakers:

Real-world usable capacity: Look for independent tests or user reports showing delivered mAh, not just the printed 10,000mAh.
Port layout: USB-C in/out is essential in 2026. At least one wired output + Qi wireless pad is ideal for earbuds and speakers.
Wired and wireless wattage: If you need quick phone top-ups, prioritize higher wired PD. If your focus is earbuds and small speakers, wireless 5–10W is fine.
Simultaneous charging: Can it handle a wireless device and a wired device at once without overheating? (See how other portable power stations manage multi-device loads.)
Certifications & seller reputation: Check return policy, warranty, and seller reviews to avoid counterfeit or poorly supported products.

Tips to get the most out of a budget wireless power bank

Charge the bank with an 18–20W USB-C charger: Faster recharge times mean less downtime.
Prefer wired for phone top-ups when you need speed: The wireless pad is great for earbuds and convenience but wired PD will be faster for phones.
Keep the bank cool: Heat shortens battery life; avoid leaving it in hot cars or in direct sun — consider portable cooling solutions if you’re in very hot environments (see our field review of compact coolers).
Cycle it monthly if stored: For long-term storage, perform one full discharge/recharge every 2–3 months to preserve battery health.
Use high-quality cables: Cheap cables can bottleneck performance and increase charge times.

Final verdict — who should buy the Cuktech 10,000mAh wireless bank?

ZDNET’s hands-on and lab-backed review frames the Cuktech as an excellent value pick in 2026 for buyers whose priorities are:

Reliable, convenient wireless topping for earbuds and small speakers.
Affordable, compact backup power for daily commutes, gym sessions, and short travel stints.
Good practical performance without premium fast-charging or laptop-support features.

If you want maximum speed for phones or a bank that can rapidly charge laptops or newer flagship phones wirelessly, step up to a higher-tier model with GaN and PD 60W+ support. But if your goal is dependable, cheap, and battery-efficient — especially for earbuds and portable audio gear — ZDNET’s testing shows the Cuktech 10,000mAh wireless bank is the best cheap pick in its class.
