Finest Costs Right this moment: Kuxiu S3 25W 10K Stable-State Energy Financial institution
The massive information in wi-fi energy banks is all about two applied sciences nowadays: super-speedy Qi2 25W charging; and semi-solid-state batteries.
The Kuxiu S3 is just not the primary semi-sold-state magnetic wi-fi energy financial institution we’ve examined—that honor goes to stablemate Kuxiu S2. Neither is it the primary 25W battery pack: that was the Ugreen MagFlow.
Nonetheless, the Kuxiu S3 is the primary—and certainly not the final—semi-solid-state 25W magnetic wi-fi energy financial institution to enter the Macworld Labs.
Certainly, not solely does it tick these bins however its additionally boasts three different top-end options: a built-in USB-C cable, built-in kickstand, and digital battery show.
When it comes to a magnetic wi-fi energy financial institution it has all of it.
- Capability: 39.5Wh (10000mAh)
- Enter charger: USB-C (30W)
- Output charger: Wi-fi (25W) & USB-C (30W)
- On check charged iPhone to: 177%
- Weight: 8.65oz (245g)
- Dimensions: 4.2 x 2.8 x 0.9 inches (10.7 x 7.1 x 2.2cm)
- Colours: Black

Qi2 25W for some, Qi2 for the remaining
Elsewhere (in Which wi-fi tech is finest in your iPhone) I’ve written extra concerning the varied wi-fi energy outputs, how they have an effect on charging velocity and which iPhone can use which charging tech.
In brief, the upper the ability output the quicker the recharge, and solely the iPhones 16 and 17 help the very quickest wi-fi tech Qi2 25W (often known as Qi 2.2). Older iPhones (from 12 on) can use 25W chargers and energy banks however are pegged again at 15W.
15W MagSafe or Qi2 wi-fi charging remains to be speedy, and quicker than discovered on older and cheaper “MagSafe-compatible” energy banks that chug alongside at 7.5W.
When it comes to wi-fi charging, the Kuxiu S3 is finest suited to iPhones 16 and later, which might reap the benefits of the complete 25W on supply.

Wi-fi vs wired
25W takes wi-fi near the charging speeds which are doable with a cabled wired charger.
When it comes to compatibility, one other issue to think about is the kind of charging port in your iPhone. A built-in cable is ok if it matches your telephone’s port. iPhones from model 15 onwards pack a USB-C charging port. Earlier fashions (14 and earlier) use Lightning cables.

The S3’s USB-C cable feels built-in however will be indifferent, though I’m undecided why that may be a bonus. It makes it a little bit extra versatile (and losable) and the connection to the ability financial institution is strong so it received’t come out with no good tug. At 10 inches (25cm) it’s longer than most. It tucks neatly round either side of the ability financial institution.
The S3’s USB-C cable is subsequently finest suited to later iPhones (15/16/17), simply as its wi-fi charging (16/17) can also be extra useful for later iPhones. That’s to not say it’s ineffective for older iPhones as it may be used to enter energy into the battery pack when it wants recharging itself.
The S3’s energy enter is rated at 30W. That’s not unhealthy however someplace shy of the EcoFlow RAPID’s unmatched enter charge of 65W.

Battery capability
The Kuxiu S2 carried out properly in our assessments, its 5000mAh (5K) battery recharging an iPhone 16 Professional from 0% to 79%. The S3 has a 10000mAh (10K) battery capability and managed to recharge that very same iPhone to 177%—so as much as 100% then one other 77% when it got here to a second recharging activity.
That’s not the highest rating we’ve had in our 10K energy financial institution assessments: the champs to date have been the Anker Zolo 10K and EcoFlow RAPID 10K, each of which scored 190%. However 177% is above common and handsomely beat the 25W Ugreen MagFlow 10K (144%).
Whereas the 5K Kuxiu S2 measures 3.3 x 2.4 x 0.4 inches (8.4 x 6 x 1.1cm) and weighs 174g, the 10K S3 is, as you’d count on, bulkier at 4.2 x 2.8 x 0.9 inches (10.7 x 7.1 x 2.2cm) and weighing in at 245g.
It’s not as slim because the aptly named Anker MagGo 10K Slim (4.1 x 2.8 x 0.58 inches) and is about the identical measurement because the 25W Ugreen MagFlow’s 4.4 x 2.8 x 0.8 inches and 254g.
Should you need an extremely slim magnetic energy financial institution look to the 5K fashions.

Semi-Stable-Cutting-edge
A semi-solid state (SSS) energy financial institution is extra energy-dense than a standard liquid electrolyte energy financial institution as a result of its semi-solid electrolyte is much less susceptible to leakage and thermal runaway. SSS is subsequently extra sturdy, safer and provides extra cost cycles so will last more.
I can see the day when airways ban liquid electrolyte energy banks; at current it restricts the capability to 100Wh. The S2’s 10K is 39.5Wh, properly inside airline rules, and being semi-solid-state safer to hold.

Clear show
You’ll be able to see precisely how a lot energy is left within the energy financial institution through its digital show, which is extra correct than different energy banks’ 4 LED indicators that allow you to know the remaining capability solely in increments of 15%.
The show is on the backside of the ability financial institution, subsequent to a spare 30W USB-C port and an influence button that switches the show on whenever you want it.
Even with that spare port plus the wi-fi pad and cable you sadly can’t cost three gadgets on the similar time, however two is feasible at a complete shared 15W: wi-fi + cable 1; wi-fi + cable 2; or cable 1 + cable 2.

Stand to consideration
If you’re utilizing your telephone to look at a streaming present or making a video name, you’ll admire the kickstand on the again that permits for both portrait or panorama orientation whereas charging wirelessly.
