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.

    This is a great power bank. It can be a little heavy but you can recharge your phone and a table multiple times. We took it on 4 day/night train vacation and at the end still had a good percentage left on the power bank.

    I cant even beging to tell you how long this charger lasts. Its take a half day to charge but it will last you 2-4 days of battery life if you are looking for an outdoor charger for your electronic devices! No need to worry about it losing charge fast and it was the best purchase ive made so far

    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.

    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!

    Needed this for over 18hours of travel and it did its job. I was able to charge my phones, tablet and accessories multiple times. The lowest it got was 57% after multiple charges. Buying a few more for family members.

    the only power bank you'll need (most likely). i love the 30k mAh pack because one charge lasts me an entire weekend vacation. it is a little bulky but i prefer the trade off of more juice for a little heavier bank. the screen is a nice upgrade from the previous dot style indicators.

    I would recommend this power bank to anyone. Its made by Energetizer . It last a long time. And im writing this review after months of use. One down side is it isnt made out of strong material, so a drop could break it. Mines is almost broke. Still worth every single penny compared to any other power bank and i bought so many

      Thanks for the thoughtful review! We're thrilled to hear the MAX 30,000mAh power bank has served you well over months of use. That kind of long-term reliability is exactly what we aim for. We do understand your concern about the casing—while it’s designed to be lightweight for its capacity, it’s not impact-resistant. If your unit is damaged or showing signs of failure, we’d be happy to help.
