Customers are saying

Customers recognize the MAX 30,000mAh power bank's exceptional battery life, allowing for multiple charges and lasting power throughout the week. Its power and portability are also praised, making it a convenient option for various devices. However, some find the device's size and weight to be substantial, impacting its portability for everyday carry. The power bank's large capacity is a significant benefit for many users, despite its size.

The charging speed is good and it works reliably when I need extra battery during the day. The build quality feels solid and it is simple to use.

    I boguth this bank based off of it already being charged and ready to go. The car I rented had a USB port that died. I couldn’t risk my phone dying as i traveled three hours to a town I’ve never been to. This one was the only one with this big of a battery AND charged. I opened it and it was at 80% and enough for my trip. While it doesnt charge quickly back to 100 after using it to 69%, its expected and shows its going to last several charges. A full day out on the town doesnt scare me as long as I have this bank. Well priced too!

    Used this battery as a recharging statuon for two phones on a trip. Topped off the phone batteries simultaneously with reserve power to repeat the charge-ups as needed during the day. Easy to recharge at night so its ready for the next day's adventures.
