Just Google "hyperjuice problems" you'll find in no time that this probuct has a chronic problem in that the high power output ports will stop delivering power. It will work for a while, but sooner or later it will fail to deliver power, and there's no way to get it working again. This is just bad, worthless enginerring - incompetence. Don't buy this. It's a seriously flawed design, and they shouldn't be allowed to sell it.
Display disappears and only visible when plugged in for a short period of time

[This review was collected as part of a promotion.] Love the display however, it only appears when you plug a cord into it and flashes for a short period of time. No way to just tap and make it come on. Also if you leave cords plugged into the pack even if you aren't using them, the unit depletes charge quickly.
[This review was collected as part of a promotion.] Battery is mostly great. Having a digital read out of charging status is great. It provides a confirmation that many devices reduce charging power(i.e. wattage) once they pass 80%. A little larger than the previous version, but that’s not a deal breaker.
Annoyingly, the device dumps all charge after a few days of not being used. I typically store the device at 40-60% charge. I’ve noticed that the charge drops to 0% after a few days of sitting idle.
[This review was collected as part of a promotion.] So far, this is the best battery pack I’ve ever owned. The display is great for keeping up with how much charge is left, but also displays how much charge is going out to devices that are plugged in or coming in from a charger when charging. I use it as a power backup for an ASUS ROG Ally, as well as charging phones, tablets, and my MacBook Pro.
[This review was collected as part of a promotion.] It doesn’t last very long and had problem with both ports working at the same time , hope the replacement is better than the first one
