    I charged the unit up to 100% and then connected several low power devices to it to use about 35 watts total. It ran for about 5 hrs. before reaching 0% charge. This means that it supplied about 175 watt hours, not the advertised capacity 276 watt hours. I would not recommend this device unless it is selling for a very large discount.

    An ultra portable powerstation!

    Where I live, we get power outages and sometimes during the weirdest of times. This is where this power station can come in handy. Also I can see usages on Halloween as well. I use a projector and laptop and I can see a good 2-3 hours of constant usage on this. In my first use, I used it to power my laptop which was low on battery. And it worked beautifully! The on board display is nice and clear in how much power is left on the station and also the amount it is currently drawing. I do like that it has a lot of options and types of plugs this has. I really like that you have the third prong hole so you can plug in items like a power strip to add more plugs to the fold. The light on the unit is handy and bright. I do like the emergency SOS and also flashing light option. With this unit to be 8 pounds, it doesn't feel so, especially with the leather handle it has. The handle is nice and thick so that in time, the leather will break in but be soft to the touch. The usb and the one USB C port is well laid out. It has a button to turn off and on that set. As well as the option to plug in a cigarette lighter power plug as well. Overall this is pretty portable for what it can do, in my opnion. I can see different types of usages this unit can do. My only gripe is how long can this last? Basically when it comes down to it, this station is basically a powerbank and serious one at that. I do like the quality and the different types of plugs. The weight, the compactness and easy to read display screen.
