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

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

    • Convenience
The iWALK Small USB-C Portable Charger is a very convenient and practical option for everyday use. Its compact size makes it easy to carry in a pocket or small bag, which is perfect for travel, work, or running errands. You do not need to carry extra cables, and it connects directly to your phone, making charging simple and hassle-free. Because of its small size, the battery capacity is limited and is best suited for charging one phone once. It works well for emergency power or a quick boost during the day, but it may not be enough for multiple full charges. Overall, it is a reliable and lightweight portable charger that is ideal for short trips or daily backup use. ... show more

    • A great little charger!
Color: White
Recently my husband and I went on a special vacation. I knew that I would be taking lots of pictures and videos and probably using my GPS. I have a travel battery that is an extremely heavy bank so I ordered this one. It is a sweet, portable charger that not only recharged my phone during a 12 hour tour but also the woman sitting in front of me on the bus! It was a game changer! ... show more

    • Does what it says, perfect portable size
Great little device to pop in your pocket or purse to carry around daily or if you are traveling. Recharges phone very fast! Only reason for 4 instead of 5 stars is re-charging it takes a long time.
