It's not a case in the traditional sense; a small anchor attaches to the phone, and the 5,000mAh battery pack connects as needed. Qi wireless charging supports numerous smartphones. A built-in stand provides convenient viewing.
How to Choose the Best Battery Case
Choosing a battery case involves balancing capacity, size, and price. If you only need occasional extra power, a portable charger might suffice. The ideal case fits comfortably in your pocket or bag while providing adequate protection. High-capacity cases may sacrifice features like quick charging and Qi charging. Qi charging is especially useful for simultaneous phone and case charging.
Battery Case FAQ
Are battery cases safe for your phone?
Yes, when used correctly. The phone draws power directly from the case; once depleted, it uses the phone's battery. Smartphones monitor charging to prevent overloading. Overheating is a potential issue if the case lacks ventilation.
Should you drain your battery case before charging?
No. Fully draining lithium-ion batteries can damage them, reducing capacity over time.
