    Love it despite being a bit big and heavy (easily fit in a fanny pack though) and overkill for what we needed it for apparently. Needed something for a full day at Universal Epic Universe and then a full day at Disney World Magic Kingdom to keep two cell phones and R36S charged. Don’t think after 3-4 charges that the energizer dropped much below 75%. Probably didn’t need to recharge it between park days but did.

    This is a very powerful charging block, which is awesome to take on a trip whether it’s a weekend or a couple weeks. You carried on the plane and if you happen to be on a plane that doesn’t have power in your seat and you’re on a longer flight, it works perfectly highly impressed with its portability. It is a little heavy because it has so much power but it’s well worth having this product.

    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.

    This is a great recharging unit. This is my second Energizer unit. You can get several charges out of it before needs to be recharged itself.

    This charger works well and as advertised. Barely moved when I charged my phone. Haven't had for very long but no complaints. It is a bit bulky and heavy but I keep it in my bag so that's not an issue for me.
