    This is an awesome charger. I used it for my sound bag to keep my receivers for my Lavalier powered for the entire day, and the next day with no issues.

    We are traveling to Europe and wanted something to charge our electronics while traveling. I was shocked when i charged it for the first time and it held the charge for days before using.

    It comes in so handy when you don’t have access to a plug in or charging port. Our girls used it when they went on their senior trip; riding a bus for 16 hours straight and it charged both phones simultaneously.

    Very heavy for a portable battery. Comes with charging cable, but you need the adapter. Had to search through several adapter until one worked with this unit.

    Great product, long lasting battery gave me 4+ charges on my iphone 13 pro max. Only room for improvements is a slightly longer charging cable and for USB-C port to also be an output rather than just input

    This power bank is awesome. Took it to Moab Utah and was concerned that camping in a desert would prevent me from charging my devices (e.g. watch, phone, ipad) and it was great. Got multiple charges off of it and still had more to go.

    We got this 30,000 unit and a 20,000 on the same day. We had recently gone through power outages because of tornado damage to feeder lines in our utility system. This one worked. However, the 20,000 unit (reviewed separately) was returned for refund as it would not charge fully and would not hold a charge.
