Do Power Banks Come Fully Charged

I use this to power and charge various gadgets in my car...everything's fully charged in appx half the time specified.

Come on guys. It's LEE Filters! Do I need to say more? Everything is perfect, but the price kills me.

[This review was collected as part of a promotion.] This is hands down the best power bank I have ever used. I fully charged it January 19th and today is February 6th and I have gotten 6 charges out of it. It is just the right size to slip into my handbag and go. I will definitelybe recommending this to everyone I know.

I bought several items just before hurricane season really set in, Florida has plenty of sunshine and humidity so my purchase of two wave 2’s was on point. Making electricity from the sun is not an easy job, dii uh e to the weight of each item or the repositioning of panels to catch the peak sunlight at the time. I used my 220 solar panels to charge each machine. They worked well but due to uncontrolled factors, I could only get 190to 200 watts from the two working together. It took awhile to get three machines fully charged, three days and then using grid power to finish. Granted the delta pro started out flat. So no wonder. Time was of the essence as you can io so to finish with the grid was a no brainer. With all systems fully charged we were ready for the onslaught of Helene. Fortunately for us we live inland 5miles so the now famous storm surge was far away. The wind is another with gust reaching upwards of 75-80 mph, and the storm when it was directly across from us was still 50miles away , headed to Big Bend to make landfall We lost power within hours of the first gusts of wind. During the next 24 hrs rain and wind snapped trees and limbs and we would have been in the dark save for our backup’s. All devices were on, cooling us through the night running internet , as long as that lasted, and cooking our meals the next morning. Considering the circumstances and my own inexperience, the system did their job. I will buy an extra battery for each wave 2, to get us through the night without stopping. But being spoiled by the convenience of the grid, I welcomed it back. Overall it was a good learning experience and I will be reassured that the EcoFlow system will be there ready to go again.

When fully charged, this battery provides me with close to 300 minutes of power. I bought it to accompany my PMW-200 camcorder, as the battery that is included with that camera is simply not enough to get through a long shoot. While it obviously does not have the same power capability as the more expensive BP-U90, I feel that I can get through very long (possibly full-day) shoots if I rely on this battery and the smaller BP-U30 that came with my camera. It's pricey, but necessary for anyone who needs a reliable power source for lengthy shoots.

I received my Delta Pro earlier this year and charged it fully in just under 2 hours. I live in Kansas so needless to say, spring is severe storm season. My use case is simply to provide backup/emergency power. Knowing that I have 3.6kWh capacity to power a fridge, freezer, lights, tv, etc in the event of any power outage helps me sleep better at night. Even through the thunder and lightning!

Amazing!! this thing works like a charm, I was able to record non-stop video last week at a live concert and still had 3 hours left on the batteries!! when fully charged two canon Lp-E6 shoud give you around 4 if not more hours of juice!!! :D. Did I mention you can hot swap them too? Yes, If you have let say 3 batteries and they are fully charged you can let two run for 4 hours and then hot swap one of them for the extra juice!! so far so good I had nothing but great experience with this baby!! Keep in mind that sony a7s can only record 29 minutes at a time, lucky me I own a Ninja Blade so I'm by passing all this limitations :) ... On top of giving you 4 hours plus power on the A7S it also has two XLR mic inputs that will convert to a normal mic jack so you can attach it to the a7s and get two channels (keep in mind this does not provide phantom power).. this is just the cherry on the top :) don't expect phantom power. Great amazing product and it comes ready to attach to any rod system rig like mine (look at pictures)

Great battery! Stays fully charged when not in use (unlike some third party batteries), and lasts a good while. I use it to power a monitor. No issues with it. Jupio seems like a solid company.

Wow, What a charge. When fully charged, these batteries have far more power to deliver extra pictures over an extended period of time. Nikon should just buy this company and use these batteries as replacement..

I've had many chargers and most have a power light and a charging light which would go out when fully charged or burned steady instead of blinking. This charger shows your power light, your charging light and a little green light that comes on when completed and I really like that. It's very hefty and extremely high-quality build in my opinion. While being a tad pricey I think the bill quality and the functionality are justified.
