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.

Customers say
Customers find the power bank excellent in quality and appreciate its portability, being convenient to carry in small cross-body bags. The compact size makes it easy to plug into phones, and customers consider it a great value for money. However, the charge rate and functionality receive mixed feedback – while some say it recharges phones quickly and works well, others report it stops charging consistently and completely stops working. Moreover, durability is a concern as the USB C head breaks off, and opinions on weight are divided between those who find it lightweight and those who say it’s heavier than expected.

Hands down best portable charger for phones
This can charge my iPhone like 3 times. I wonât travel without it. I even keep it in my purse when not traveling and it has saved my friends phone from dying. I love how small and compact it is. I love that you can still use your phone so easily while charging.

The perfect charger for my travel adventures
The perfect charger for my travel adventures. I keep this charged and in my purse or carry on bag just in case my phone or Kindle battery is running low. It’s lightweight and the size fits in the palm of my hand, so it’s easy to stow. I find it both charges my phone and recharges quickly. This is actually my second one so I keep one charging at home and have one for use as I am out and about.

Great size
Iâve been using this small portable charger for a little while now, and overall, Iâm quite happy with it. Itâs compact, lightweight, and fits easily in my bag. The build quality feels solid, and it charges my phone quickly, which is a big plus when Iâm out and about with a low battery.The only downside is that it comes with a USB-C connector, which doesnât work directly with my iPhone. I had to purchase a separate USB-C to Lightning adapter to use it. Itâs not a huge issue, but something iPhone users should be aware of before buying.

Works great
This charger works really well for long rounds on the golf course. It is small and compact and fits easily anywhere the phone fits. The charger has not run out yet while in use. Good value for the money.

Love these chargers
Always trust iwalk chargers. We must have at least 8 in this house. Just switched to usb-c with phone upgrades. I make sure my teens always have one with them in case their phones run low on battery they will always have a battery. Super easy to always have with you. They are small and perfect to throw in your pocket!

Worked great while traveling, the airport charging is always inconsistent if they work at all. I enjoyed the cordless charging kept my bad organized

Light and small, so this is perfect for travel. Only has the one connector though – itâs compatible with my iPhone but not my iPad.
