Why do you claim that the Jumpr Quad is a "4000-9200 mAh power bank?" It's only a 1000-2300 mAh power bank since the output voltage is 4.8-5 V, while each battery's output is only 1.2 V.

Asked by: JCar
The Jumpr Quad doesn't provide 9200 mAH with 4 AA batteries. I like EnerPlex, but that's a false claim. Since the batteries are used in series in order to achieve the 5V power output, their milli Amp Hours don't add together. If they were used in parallel, then sure, you would have a 1.2 V power supply with 4x2300=9200mAH. But that wouldn't be high enough voltage for USB. So they're used in series, which means that their voltages stack, but not their mAH. 4x1.2V = 4.8V power supply with 2300 mAH. Talking about mAH without taking voltage into consideration doesn't make sense. So we have to include the ~5V output voltage of the power supply, in which case 2300 mAH is the correct value, not 9200.

Will these charge the newer android phones like Samsung S6 or S7 that draws up to 2A of power?

Asked by: Erwin
The Jumpr Quad features overcurrent protection which powers down the Jumpr Quad when more than 1A is drawn from the unit. If your device requires more than 1A, it will not be compatible.

How long does it take to charge 2x 2000mAh AA cells and 4x AA cells? What is the charge current given to each cell during charge?

Asked by: Optiri
If the charging input is 1A. Divide it by 2 and you'll get the number of hours it will charge. But also assume that gadget like these only use 300 - 500mah when charging.

I just got one of these and like it quite a bit. One thing I'm noticing is that when I have the switch in the "Off" position, the bottom light remains on. Is this supposed to function like this?

What happens when a device tries to pull more than 1A while the Jumpr Quad is in Output mode (like most smartphones do now)? It looks like the Quad will just turn off and will not charge the device at all, turning it into a pretty useless power bank.

Asked by: JCar
Thanks for your inquiry! If any device plugged in to the Jumpr Quad's USB port tries to draw more than 1A, the Jumpr Quad will power down as a protection measure.

Can I use regular AA alkaline or non-rechargeable batteries as a power source?

Asked by: Alfonse
The Jumpr Quad's battery function was designed to be powered by rechargeable NiMH batteries, so this is not something that we recommend.

I have two-way radios with 3 AA NiMH battery pack.  Can a battery pack be inserted and charged on this device?  Would I have to add an additional AA battery to complete the series of 4 AA batteries?

Asked by: Stan
The Jumpr Quad is only able to charge in pairs, so you would need to add another rechargeable NiMH battery to the Quad in order to charge your 3-battery set.
