    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

    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!

    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.

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

    This has been so helpful to have! I’ve been in several situations recently where the car charger didn’t work & my phone was almost dead. Charged things right up. Also use it while traveling so I’m not plugged into an unknown outlet.
