    Its not too heavy and seems well made. At 30w charging it takes about 7-7.5 hours to charge. This charged my 11,200 mah tablet battery from 0-100% pretty slowly, 4 hrs, but there was still 70% left on this power bank, thats insane! If i had a complaint it would be it doesn’t show how many watts its inputing or outputting. Other than that its been great so far. I haven’t owned it for long but I hope it lasts for at least 2 -3 years

    Love this Energizer Portable Charger. Fast charges my iPad and phone quickly without draining the charger, has a lot of charges for my iPad and phone. Lost count on how many charges it has but it’s plenty. Take it with me on trips to family or just riding along just in case my iPad or phone charge runs low. Highly recommend this Portable Charger.

    This power bank is a beast! 50000mAh is no joke, it charges my phone like a dozen times before needing a recharge itself. Totally worth every penny, it's a lifesaver on trips and during power outages. Highly recommend it to anyone who needs a reliable and powerful portable charger. Seriously, buy it, you won't regret it!

    Lasts a very long time instruction said to charge it and then drain it back down and what a chore that was had to leave the light on and plug it in to all my devices and then that took 3-4 days!

    Ive had this for about a week. I havent used it for anything but charging my cell phone. But ive only charged it once since purchase and have used it to fully charge my phone 6 times before having to recharge! Amazing product that actually can be called a useful portable charger

    The only drawback for me is its capacity, 30AH. Fortunately, it has a 50AH version.

    This power bank is awesome. I am getting about 170 hours of charge time for my iPhone. We also have rechargeable lamps for when the power goes out. My husband and I loved this power bank so much that we bought another one so we always have one fully charged at our disposal. We purchased these on sale for almost half price.

    i got this to replace a ten year old 12,000 mAh power bank. this has become a mini usb power station in my backpack. i have been getting around 4 charges for a 7,500 mAh phone, 3 for a 5,000 mAh tablet and some charges for some other much smaller mAh batterys.

    This is a chunky monkey. It has like 180wh of juice. Charges my phone a ton of times. The light is underwhelming and probably wont get any use. Thats not what i bought it for though.
