You can now borrow a power bank at any 7-11 and leave it back at any other branch. The rental fee is NT$12 per hour, with a 24-hour max charge of NT$36 and a 72-hour maximum rental period. They will hold NT$300 on your card until you return it. If you want to cancel a transaction, you can also return it within 10 minutes without charge. You can check out a list of participating stores here! Wireless and wired charging are both available for Android and Apple.

First, check to see if the Ibon machine at the 7-11 you’re at has any power banks inserted at the bottom. If not, they might all have been rented, or it might not be a participating store. If you do see power banks, you can follow the steps below to rent:

Step 1: At the Ibon Machine main menu, hit 「生活服務」 (everyday services)

Step 2: Hit 「行動電源租賃」 (Power bank rental)

Step 3: Pick your method of payment. If you’re not paying by iCash, the first option allows for credit/debit card payments: 「手機掃描租借」 (Rent by scanning QR code with your phone).

Step 4: Agree to the conditions, by clicking 「同意」 (Agree)

Step 5: Scan the QR code with your phone, and you’ll be linked to the payment website, or to Line Pay (depending on your preference):

You’ll see this screen, while the website loads, so make sure you’re connected to the internet:

Step 6: Click 「開始服務」 (Start), and ensure you’ve ticked the box agreeing to conditions of use.

Step 7: Choose your method of payment by ticking the corresponding box
Open Wallet, ICashPay, Line Pay or credit card. The fifth box allows you to donate your rental receipt to charity if ticked. In the box under that, you should enter your mobile phone number and below that is an optional coupon number box.

Step 8: Make the payment for the NT$300 deposit with your credit card (if that was your chosen option). After that, you’re good to go!

Step 9: Remove the power bank indicated by the flashing light under the Ibon interface.
