Hi YingC Thanks for your comment. We understand that pricing is an important factor. While there are higher-capacity options available elsewhere, this 5,000mAh model is designed for portability, MagSafe compatibility, and fast 18W output — features that often come with a premium. We’ll continue working to offer better value across all our products. --Energizer PowerPacks Service Team

Having a portable battery is a must, especially if you're using your phone's camera as your base camera. The fact that this one has the wireless changing capability, is a bonus.

It's relatively thick for its capacity and did not really stick securely to the phone but for the price I paid, I can tolerate it. It charges rather slow and does heat up a bit. I'd probably use this as a daily power bank for any day to day activity but if I'm traveling, I'm sticking with my trusted Anker power bank

Dont buy this item guys, as bad as $3 power bank from temu. Magnet is not enough strong to stick, battery life is terrible, recharging time is too long and if you are not putting this in center exactly the charging didnt continue.
No, I would not recommend this to a friend

Hi Robi, We’re sorry the power bank didn’t meet your expectations regarding magnet strength, battery life, and charging alignment. This model uses MagSafe-compatible magnetic positioning, which requires precise alignment for stable charging. If the magnet feels weak or performance is poor, it may indicate a defective unit. Please contact Energizer support for assistance or a possible replacement:
