Use it daily for fast charging devices at home

I bought this for emergencies. But I use it daily for fast charging my devices. It is way faster than any wall outlet. I also can take it with me anywhere if my devices need charging. I also live in an area prone to power outages lasting a few hours, so this is a handy device to always have on hand. I am ready to buy an even bigger one for real emergencies and road trips.

Worth every penny

Having gone through three power outages in the last six weeks including one that lasted 3 1/2 days I needed to do something. I am handicapped and housebound. This generator is worth every penny. I can recharge my phone and also plug in electrical items. It provides 100 hours of power.
