EnerPlex Jumpr Prime 4400 is rated 3.7 out of 5 by 3.
Rated 4 out of 5 by from Would have been 5 if only the manual was more comp I just got a Jumpr Prime 4400 yesterday, and I would give the product itself 5 star, but 0 star for the absence of flashlight instruction.I could not figure out how to turn on the flashlight until I found an outdated old manual through google that says I have to press 5 seconds. That's quite a bit longer than the usual long press.Then I found out that it goes out automatically after 30 seconds. And then after a couple trys of 30 seconds, I discovered that if you short press once after flashlight is on, it stays on (or at least for the couple minutes I waited).Great feature, right? Except why wasn't this mentioned on the manual or anywhere at all?

I have one of these ,for some reason when I plug it into my Samsung Galaxy S7 it turns off, not my phone the enerplex. Is it not compatible with the Samsung Galaxy S7?

Asked by: Robert
Robert its sounds like the S7 may have a higher amp requirement than your unit can provide. For troubleshooting help please contact us at

Is there an adapter available to transition from micro usb to iphone power input?

Asked by: RJPace
Thanks for your inquiry! You should not need an adapter to power an iPhone, just use the sync & charge cable which came with your iPhone by plugging the USB end of that cable into the USB output on the Jumpr.

Does Jumpr Prime products work with HTC One M9?  There are different types of microUSB connections and the M9 doesn't seem to work with most. Thanks!

Asked by: IhateHTC
We haven't done any specific testing with the HTC One M9, however, most phones manufactured after the mid-2000s have standardized so they use a micro-USB input for charging. Micro-USB 3.0 (as seen on many new smartphone models) is backward compatible with previous micro-USB versions.Regardless, the Jumpr Prime has standard USB outputs which you can plug the HTC One M9's included cable into for charging.

Do you supply the INPUT power source? Need more information.

Asked by: Martytwo
The input power source is a wall outlet (used via USB wall adapter), laptop/computer USB port, or one of our Kickr solar panels (sold separately).The input port is a standard micro-USB port and the device does come with a standard USB-to-micro USB cable.

Why is one USB port Blue?

Asked by: WakaFlocka
lack of instruction is the worst part of this product, that manual has practically no use except for the power percentage vs. indicator chart.You have to discover it yourself for a lot.If you look closely, the 2 USB outputs have tiny raised lightning marks by them. Blue one has two lightning marks and black one has only one, so 1.5 a max. for blue and 1 a max. for black.

I plugged mine in to charge and let it sit there for a about half a day and when I came back, there was still only two blue dots on the little screen as oppose to three. Do these jumpers take a long time to charge? Or am I not doing something correctly? 

Asked by: MelD
Charging time will very much depend on your power source! For example, a power source which is 1000mA can take up to 5 hours to charge from 0 - 100% (a 2000mA power source would take around 3 hours). As well, many USB ports on computers still only provide around 500mA output. Charging time can also be lengthened if you are trying to charge more than one device at the same time from the same USB hub.

bought the jumper prime charger,works great so far. Read instructions which say"simply connect the cable to one of the two USB interface ports on the JPrime then connect cable to device. Should say ports are low & high( ⚡⚡ ) overheated my phone

Asked by: E kal
The Jumpr Prime has two ports, one will output at 1A, the other port will output at 1.5A. Both of these are fairly standard for charging phones (some phone chargers will even output at 2.1-2.4A).As further protection, phones have internal technology which limits the amount of input it will accept to prevent overloading. If overheating occurs, this would be a malfunction within the phone itself.
