Why my power bank provide fewer charges than expect?
Usually an external battery could supply 60%-70% power to other devices. Approximately 30-40% of the battery capacity is lost in circuit heat and voltage conversions.So a fully charged INIU 20000mAh can offer 12000-14000 mAh to your devices.
How to calculate the possible number of charges?
“Industry-standard formula: (Rated capacity × 65%) ÷ Device battery capacity ≈ Number of Charges.
eg. (20,000mAh Powerbank × 0.65) ÷ 3279mAh iPhone14 battery ≈ 4.0 charges”
How long does it take to 100% recharge?
“It depends on the power of the wall charger used:
20W charger – 5.4 hrs, 15W fast charger – 6.6 hrs.
Note: Please recharge via the USB-C port.”
Why doesn’t it charge at max power all the time?
INIU power banks feature a Smart Temperature Monitoring System that adjusts output to prevent overheating. It delivers max power when your device is low, then reduces power to protect your battery and improve efficiency.
Is it allowed on airplanes?
Yes, our 20000mAh power bank meets the regulations of TSA(Transportation Security Administration) for carring board(≤100wh≈27,027mAh).

Overall, a fantastic power bank that’s well designed and reliable. Highly recommended!
Excellent power bank, very happy with this purchase. It’s extremely compact for its capacity and easy to carry around. Charging speed is fast and stable, and the build quality feels solid and premium.A big bonus is the built-in flashlight — a really nice extra that comes in handy, especially at night or while traveling. The display is clear and makes it easy to check the battery level.

Worth the money
Quality is superb compared to other charging docs. Charges fast with juice leftover. Comes with a mini charger that doubles as a wrist holder. Small enough to fit in your back pocket
Family Matters –
Love it
A little heavier than I expected but I love the size. The cable is short with has its pros and cons. The USB C cable doubles as a hand strap but I’m not sure if I trust it as a strap. Battery life is pretty good as I use it for food delivery services and it’s still at 50 or 60 % by the end of an 8 hour shift. It’s heavy which usually indicates better quality. When charging it, it’s pretty quick.

Great size, dependable, perfect for travel
Great charger, comes with cords, perfect size for traveling. My only issue is it’s a bit on the heavy side but other than than I’m very happy with it.

It’s worth it, especially at sub $30.
I work 10 and 1/2 hour shifts and listen to music. When my phone (S23 Ultra) gets below 30% I let it charge. This charger gets it up to about 90% pretty quickly and still has 80% juice left. 1% on the charger gets my phone up by about 3%. I charge it after work but could use it every day and get by only recharging it on the weekends. It’s about the size of a pack of Newport shorts and a little heavy. But it’s compact to be a seriously heavy duty portable charger.

Great power bank
Great size for vacation, work, to keep around the house when the kids are on the move etc.Will fit in your pocket if your needing to take 1000’s of pictures at SEMA… Seriously a great bank that’s seriously robust, reasonably priced and the lanyard USB c is pretty genius

Amazing!!
Charges my phone and other items so fast. It’s nice and clean looking. Haven’t noticed any overheating. Great size – fires nicely in pocket.

Works well but heavy
The battery so far has been working well. Charged my phone and recharges fairly quick. One thing to note is that it is quite heavy. I took it with me on vacation and it was on the heavy side. The weight is noticeable after a day of walking around with it in my day bag.

Dopo aver provato diversi power bank nel tempo, posso dire che questo INIU da 20000mAh è davvero tra i migliori che abbia mai acquistato.✅ Autonomia eccezionale: riesco a ricaricare completamente il mio smartphone (Samsung S23) almeno 4 volte, e resta ancora un po’ di carica.⚡ Ricarica rapida: supporta la ricarica veloce sia in ingresso che in uscita — il telefono torna al 100% in poco più di un’ora.🔌 Tre porte utilissime: posso caricare contemporaneamente telefono, cuffie e smartwatch senza problemi.💡 Torcia integrata: un piccolo extra che torna sempre comodo, soprattutto in viaggio.📱 Display digitale preciso: mostra la percentuale esatta di batteria residua, molto più pratico rispetto alle solite 4 lucine.In generale, costruzione solida, design elegante e ottimo rapporto qualità-prezzo.Perfetto da tenere in borsa o nello zaino per viaggi, giornate lunghe fuori casa o emergenze.Consigliatissimo! 🔋💯

Do I recommend it , Short Answer Yes! I’m dept reviewI bought this because of the changing in times we are living in & the power going out here in Ireland, been in my mid 30’s it’s honestly unheard of the power going downBut it happens more & more often unfortunately this is why I bought it & to update for ones I bought years ago with a well known safe brandI own over ten power banks, This build quality is in the top 3 it really is!You get a full 3 year warranty with itIt’s super sleek , it’s Really well made , it’s small it’s not that heavy for the mAh it’s really notIt has a really nice display that’s big & clear , mine came with 55% which is the normYou get a USB A to USB C cable it’s not long maybe 6/7 inches ( that’s my only con which is nitpicking as they often don’t come with one )The packaging is really nice , it’s very straight forward, push on , 2 fast pushes for the LED Light & sane to turn off super easy.Been USB C , It can recharge a lot faster & it’s really quick to charge my IPhone 11 usb A to LightenPeople might think it’s heavy , For the power 20,000mAh it’s really not!, it’s really sleek & has a soft feel like velvet is the best way I can explain it but it’s really sturdy!But you can tell it’s made to last & anything with 3 year’s warranty at this price with this much power & at the speed it charges your phone or itselfIt’s a steal , such a bargain!I 100% recommend this. Buy it!*EDIT – UPDATE* – I charged this to 90% ( btw is the norm don’t charge to 100% and put stress on the batteries just sitting there as it’s just sitting there )So 7 weeks later I checked it today 5th of June 2025 , it’s still at 90% & I plugged it in my phone for 15 mins , didn’t get hot , works perfectly as expected with the build quality reviews & from tech sites it’s the cheap but amazing quality powerbank( build quality is my number 1 and it meets it it’s no different than my Ankler or Ugreen )now I know I can put this in the drawer knowing when the power goes Click! I’m good ,is such a peace of mind , this is the very same quality as Ankler & Ugreen imo, power is power at the end of the day, yes INIU is a new company, but with millions sold in the states & all over Europe & no horror stories, it’s such a peace of mind ,also it’s not heavy IMO , it’s not it weight is about 4 times your phone ( if that is heavy to you ) if you are going out for a day long train or an overnight event 10,000mAh is Loads ,imo this is for an emergency , I can’t rate it higher for the cost , build quality , power holding , and the price in around €20 quid it’s such a steal ,Said I’d update to help someone to decide! As build quality is the most important thing to me then the power & it does both whats it ment to , on the tin so to speakAnd who doesn’t like a bargain , it will definitely go up in price. Hope this helps someone out

Batterie achetée le 1er Février 2025.Ma batterie a explosé cette nuit vendredi 22 Août à la tête de mon lit.Je l’avais débranché vers 23h, elle était chargée à 90%, elle n’est jamais tombée ni choquée.ET ELLE A EXPLOSÉ à 6h ce matin sans aucune raison alors qu’elle n’était pas en charge.La fumée et le feux était incontrôlable.Fort heureusement la fenêtre de la chambre était ouverte et jai pu la jeter hors de la pièce.En 3 secondes beaucoup de dégâts.Jamais plus cette batterie.Tres dangereuxCette fois j’espère que ce commentaire apparaîtra…Je signale d’ailleurs ne pas avoir été contacté ni pour la garantie ni pour des explications, incroyable.Olivier
