Once again Corey, thank you for such a prompt reply.
Well it is nice to hear your problem has been resolved with a replacement unit.
Considering the same problem is occurring with both my ArkPak units, i am wondering if a replacement would solve the issue?
Unless of course, if newer ArkPak units have been slightly modified?
I know ArkCorp made this unit to be used, not stored, but the reality is, it is being stored 90% of the time until we next go away.
Just like our fridges etc.... I'd just like to best protect and maintain my expensive batteries during these times of storage.
On another note, those charging mobile phones, you will get a much faster charge using your car charger in the ArkPak cigarette outlets than the USB outlet.
USB outlet is limited to 500mA, you will attain a full 1amp (or what ever your charger is rated at) using the 12V cigarette.
Considering most smart phones are quite power hungry and can use 300mA when the screen is on full brightness and 3G connection is being used, at 500mA, you are only tipping in 200mA, making it a very slow charge.
Using the 12Volt cigarette outlet and your vehicle charger, you can achieve 700mA of charging current while the phone is in use, turned on.
This has been tested with the Samsung Galaxy S3 4G, Iphone 3gs and Iphone 4.
Some products are more or less sensitive to available charging currents, the Samsung range of phones and tablets and very sensitive to charging currents.
Hopefully this may help anyone suffering slow charging of their mobile device.
This is not specific just to the ArkPak, it is the same across many charging platforms, including the 240V/110V main power chargers.
