Wow

[This review was collected as part of a promotion.] I didn't know that these kind of outlets existed until they let me try one out! We used it for our gaming systems and it works amazingly. We thankfully haven't had crazy weather yet but eventually, to test it out even more!

Amazing back-up tower!!

[This review was collected as part of a promotion.] This back-up tower is amazing! We have had a few power outages lately and the battery life on this far surpasses anything we have had before. Kept everything on to give us time to safely power off all devices or even make a phone call last second if need be. It is also the perfect size to fit on any shelf next to router, modem etc. highly recommend this product!!
