    This power bank works great. The only problem is I ordered it for my laptop computer but port are not compatible with my computer. I have to say I am not happy with the customer service department because they said it would work. I did use the bank to charge my cell phone, hot spot and some other thinks.

    Value for money. The only thing that would be nice is to get a fast plug that can charge faster. Well if you use your fast charging plug to charge the battery it does but it’s just a nice thing. Overa,, it has given me the value for money.

    The only problem I have is how heavy it gets sometimes when I have in my pocket. When it’s in my backpack I hardly notice and most of the time it is there.

    High capacity power bank. Can charge iPhone at least 7-8 times from empty to full. Only downside is that you can't bring this on the plane as it's over the allowed limit for capacity

    Battery pack i a little heavy, but packs a big punch especially for the cost, so really like it so far. I really like the fact it has a digital display to tell you how much charge it has.

      Hi FIDELV
      Thanks for the great review! We're glad the Ultimate Lithium 30,000mAh power bank is delivering the power and versatility you need. While the size adds a bit of weight, being able to charge three devices at once makes it a true powerhouse — perfect for long days or travel.

    Very good for the price. It will not give a rapid recharge on a dead device but if you plug it in before the device dies, it will extend the life. Helpful on a trip.

    I use this as my back-up charger when I am on the go. It also works as a flashlight, which is also convenient during a power outage.
