Description

Why is my power bank providing fewer charges than expected ? The capacity reduction during charging is due to a 20% to 35% energy loss in the battery cells and conversion circuitry. Therefore, a fully charged iWALK mini Portable Charger offers an estimated 2750mAh to 3500mAh to power devices. How many times this power bank will charge my iPhone when fully recharged ? To estimate charges,use this formula: (Power Bank Capacity × 0.66) ÷ Device Battery Capacity. For example, an iPhone 15 with a 3,349mAh battery can receive about 0.88 charges from a 4,500mAh power bank (calculated as (4,500mAh × 0.66) ÷ 3,349mAh). Getting hot when charing, is it normal ? Our portablle chatger support 20W fast charging for your iPhone, which may cause some warmth,please feel free to use it since this power bank has built-in over-heat protection. Why does the device become hot when used ? When the power of the mobile phone or power bank is less than 30%, the power will reach the maximum value and the temperature of the product will rise rapidly and significantly. This is normal. Which iPhone models this will be compatible with iPhone 15, iPhone 15 Plus, iPhone 15 Pro, iPhone 15 Pro Max, iPhone 16, iPhone 16 Plus, iPhone 16 Pro, iPhone 16 Pro Max, iPhone 17, iPhone 17 Plus, iPhone 17 Pro, iPhone 17 Pro Max

    • Keeps the phone portable while being charged
Color: White
Worked great for my 4 week trip. Smaller size makes it easier to carry. My phone (galaxy S10e) is old and has small battery capacity so it often ran out of battery with more google map usage, background battery uses from public transportation apps, and taking photos and videos. This was a lifesaver. Either my sister or I used it so it was used almost daily. I wished I bought two so my sister and I could use one each. Much easier and lighter than the bigger rectangular higher capacity power banks. Not having to carry a usb cable is a plus. Being able to keep the phone completely portable even with this power bank attached is awesome. There were times my sister used this, and I had to resort back to bigger power banks (slightly larger than my phone) with built in cable (kind of short). It was charging my phone faster than the iWalker did, but I often disconnected the cable so i could use my phone to take photos or videos from the angle I wanted. Carrying the bigger power bank with the phone gets tiring quickly. If I carried a longer cable to use with the bigger power bank so the power bank could stay in a bag it may have been different. IWalker charged my galaxy S10e in fast charging mode. However, with constant use of the phone while being charged it took a long time before the charge got >90%. Since my phone has a small battery capacity this power bank fully charged my phone, but not my sister's iPhone. She noticed it would charge fast when her phone's battery was very low but once the iPhone battery was back in high % it slowed down significantly. I haven't timed how long it takes to charge the iWalker as I plugged it in overnight and woke up with it fully charged. ... show more

    • Different colors for each family member = no more missing chargers
Color: Pink
Review Image by Shannon
This little charger has been an absolute game changer! I love that it plugs directly into my phone, so I can charge while walking around without being tethered to a wall or carrying a bulky battery pack with cords hanging everywhere. It’s surprisingly lightweight, so my phone is still easy to hold and use while it’s charging. It works so well that we ended up buying one in a different color for every family member. Before that, my teens were constantly “borrowing” our chargers—now they can only take their own! 😂 The charger itself powers back up quickly, and it charges my phone fast when I need it most. It’s perfect for travel, sporting events, concerts, errands, or any time you’re away from an outlet. If you’re on the fence, I’d definitely recommend it! ... show more

    • Love this!
Color: White
Review Image by Freida
This portable charger is honestly amazing. It’s super small, so it’s easy to carry around in your pocket or bag without even noticing it. I also love that it plugs directly into your phone—no wires at all, which means no tangling or extra clutter. It charges my phone pretty fast, which is a huge plus when I’m on the go. There are also little indicator lights (1–3 dots) that show how much battery is left, which makes it really easy to keep track. The only thing is it takes a few hours to fully recharge the charger itself, so I like to have it charge through the night - this way by the next day it's full and I can use it. Definitely worth it! ... show more

    • Good product for the price
Color: White
It is a good product. I did not expect the battery (after fully charging it) to last over a week as a few people had mentioned in the reviews that the battery automatically discharges if it’s not used. I carried it on a hiking trip and it effectively charged my iPhone 17pro once, pretty well. I had some more charge left so I charged another phone partially too. ... show more

    • Decent
Color: White
I mainly got it because where I sleep there’s no charger and I always forget to charge my phone before I go to sleep. So I got this little charger to charge my phone while I read in bed. The size is convenient, it’s not that heavy but it has some weight to it, battery life is weird cause I’ll charge it but not use it all day and it’s already has 1 battery lvl left and won’t charge my phone, so maybe I’m using it wrong? But charges my phone well not extremely fast but chargers a good amount and will overheat ofc if u are on ur phone while charging it. Btw I do have a iPhone 15 pro max -sooo could just be the phone idk. But it’s nice decent ... show more

    • It works very slow. It takes a long time and I know I won’t buy it again.
Color: White
Doesn’t work as well as I thought it should. It takes forever to charge and it takes forever to discharge into a iPad or phone or something like that and it never charges stuff to 100% that I saw anyway.
