Monster PowerCard v2 Our Testing and Review Pressing on the power button once turns on the LEDs to indicate how much juice is left, something we'll get into a bit later, while long pressing initiates the charging process.

Getting the basics out of the way we unpackaged our PowerCard and as with most geeks just jumped right in without reading the manual (not that it tells you much!).

As per usual right out of the box you need to charge it first, we didn't check the indicator to see how dead it was but I wouldn't rush to the store expecting to get a full charge of emergency power right from the gate!Īside from a very short manual you'll receive a short microUSB to USB cable for both charging the PowerCard and charging your device. In order to keep things compact the cable is about 5-6" long, if more length is needed then I suggest using your phones own USB cable. When charging you'll notice the 3 blue LEDs flash and continue to do so until it obtains full charge. The manual says you can expect a full charge from a USB AC power adapter in about 2 hours or less, or from a standard notebook USB port in about 3.5 hours. We originally charged ours for about 30mins to a full charge and then a second time after testing and from what was completely drained it took about 45mins to charge. Given that the battery only has a 1650 mAh capacity we figured it wouldn't make much sense to try to charge multiple devices, or even a single large capacity device to full charge. Since we figure most geeks are like us and only think to use their back-up power packs when they truly need them the most we decide we'd start charging our phone at around 10% battery, of course we could always just use the Ultra Power Saving Mode, but that just isn't as much fun! So we tested our PowerCard on our Samsung Galaxy S5 with its 2800 mAh battery.
With 10% battery on our Galaxy S5 we let the PowerCard charge for about 20mins. At that time it went totally dead which as first we thought might be due to over heating because it was very hot to the touch.
