    Does take a while to charge but other than that it genuinely charges pretty quick without easing a lot of its own battery

    Easy to use, need your own cables, lasts a while. Is on the heavier size, but it’s also cheaper than lighter ones

      Hi JacobRomelhardt,
      Thanks for your thoughtful review! We're glad to hear the power bank is serving you well as a backup. The larger capacity does add some weight, but it’s great to know you found it to be a cost-effective option. For lighter travel, our slim 10,000mAh models might be worth exploring next time.

    I get scared when buying battery charges for trips. Because they usually don't last long or don't add up to what is describe. But this one, is different. It is bulky and heavy. So I would carry this if you have a backpack to charge up your devices

    Used this for a trip and it kept my phone charged up to 100% many times without having to charge the power bank itself. Super worth it!!

    Extremely fast charging and long lasting. I have an Iphone 14 Pro and it uses about 10% of the battery to charge it fully. The only downside is it does take ages to charge but great for camping or festivals.

    Wonderful battery - too slow to recharge

    A fine battery pack. A little heavy, but considering its capacity, no surprise. Multiple outputs is what is to be exoected. I'd like to be able to charge it either on the C port or the standard USB port, but the instructions don't day anything about that. My only real complaint is the low charging rate - 2 amps. For this 30 amp-hour battery, this mean an over night recharge time!
