I love this bright, colorful case! I’ve used only Loopy cases for the past 8 years, but decided to give this a try. I like it even better! It is easier on my hands to hold the phone up and scroll on social media. I like the kickstand too! I’d recommend Walli cases to everyone.

Love this print! The small loop is great. It’s the perfect size for me to hang onto my phone but keeps the phone from being super bulky in my pocket. This is my favorite Walli case yet!

Frequently Asked Questions
What is a portable phone charger power bank?
A portable phone charger power bank is an external battery device that stores electrical energy, allowing you to recharge your smartphone, tablet, or other USB-powered devices without needing a wall outlet. Walli Cases offers the Power Boost collection, which combines a 5000mAh portable charger with stylish designs that complement their phone case ecosystem, providing convenient on-the-go charging in a fashionable package.
What capacity power bank do I really need for daily phone charging?
For most smartphone users, a 5000mAh power bank provides one complete charge for devices with battery capacities between 3000-4000mAh, which covers the majority of modern phones. This capacity strikes an optimal balance between usefulness and portability - enough to get you through a full day without the bulk of 10,000mAh+ models that are better suited for multi-day trips. The Walli Power Boost features a 5000mAh capacity designed for everyday carry, offering sufficient power to fully recharge your iPhone device once while remaining compact enough to slip into a pocket or small purse.
Are portable power banks allowed on airplanes and in travel?
Power banks are permitted in carry-on luggage on most airlines but prohibited in checked baggage due to lithium-ion battery fire risks. TSA and international aviation authorities typically allow power banks up to 100Wh (approximately 27,000mAh at 3.7V) without special approval; anything larger requires airline permission. Always carry power banks in your personal item or carry-on bag. The Walli Power Boost at 5000mAh (approximately 18.5Wh) falls well within all airline limits, making it an ideal travel companion for keeping your phone charged during flights, layovers, and adventures without any regulatory concerns.
How long do portable phone battery packs typically last?
Quality lithium-ion power banks typically maintain 80% of their original capacity after 300-500 full charge cycles, which translates to 2-3 years of regular use for most people. Lifespan depends on usage frequency, storage conditions (extreme heat degrades batteries faster), and charging habits - partial charges are gentler than always draining to zero. Walli Cases backs their Power Boost collection with quality construction designed for durability, and their customer reviews consistently praise the longevity and reliability of their accessories, with many customers reporting years of dependable use across their product line.
How do I choose the best portable power bank for my needs?
The best portable power bank depends on three factors: capacity (measured in mAh, which determines how many charges you'll get), portability (size and weight for daily carry), and charging method (wired USB or wireless MagSafe). A 5000mAh power bank typically provides one full charge for most smartphones, making it ideal for daily use without excessive bulk. The Walli Power Boost collection features a 5000mAh capacity in a compact design available in different patterns and colors, balancing practical charging capability with a slim profile that fits easily in pockets or bags.
