External USB Charging/Battery Packs (On the Go Charging)

post #1 of 3
Thread Starter 

I have  a lot of business travel coming my way over the next few months.  There will be plenty of times when I won't be near a wall outlet, and am looking for portable ways to re-charge my DAP & portable amp(s).  I see battery packs all over the place for iDevices/Android.  Are there compatibility concerns I should look out for?  Any possible issues w/ frying non-iDevice/Android devices?  For example, I was looking at this one--> http://www.amazon.com/dp/B00D5T3QK4/ref=wl_it_dp_o_pC_nS_ttl?_encoding=UTF8&colid=1WBCS8JLMISE1&coliid=I3TUM91KOPD9GI

 

I did try searching the forums, but couldn't find a relevant thread....

Unlikely you need worry unless your device is very old. When the battery is full it will stop charging whether you charge from a 500mA standard USB port equivalent or 2100mA iPad charger. The latter will just charge it faster. Your first clue would be those backup batteries would come with 900 warnings not to use with certain devices or in certain ways. They don't. I thought i was cool when I got my 5000mAh but I was an early adopter. Now there are some big time options out there like yours. Must not covet others batteries.

The only issue you may have is reverse polarity , look that up online and make sure all your dc equipment is normal polarity. If it is negative polarity it will blow the power fuse inside the equipment you plug in or damage the internals permanently. Please check all your equipment before plugging it in, you can always get a polarity reversing cable off ebay if you need to
