How fast does the U-Stone charge compatible products?
595514
The U-Stone's micro control unit will detect the maximum current the product is able to charge at and charge it at that speed so your phone will be safe.

Pwr+ Rapid Charger charges HD Fire in under 2 hours. Don't have HDX so can't answer that one.

Sorry - I haven't timed it. I do know that the slots are paired and when you have two in alternate lots, it charges at a slower rate.

Yes, it charges very quickly compared to other chargers. I ordered two of these and loved the speedy charging ability. However, the speaker in one of mine got fuzzy after only a few months of gentle use.

Concur; the charger is rated for 120 VAC 60 Hz at 0.100 Amps only. It is not a universal input charger. Not sure about the fast charger. I can recommend the batteries as having fast charge rate and slow self-discharge. Handy having two so one is standby always. This package is worth the $100 charged.

That depends on the size of the battery in your device. My Lumia icon charges in about an hour and a half

As previously stated by Mr. Gallo, the additional feature of the Flash Charge button on the B&D; L2AFCBST charger will get a battery in this series running in some 10 minutes with a 30% charge from zero, a feature the B&D; L2AFC-OPE does not have. This, in and of itself, may be a deciding factor in which fast charger you purchase depending on your needs and the number of batteries you own. The difference in price between the two units in relatively minor.

Yes it will charge faster. I can't be exact on how much more, but I would say at least 50% faster.

It will charge two UBS. It is three pronged and probably won't work with converters, since they are usually for two pronged devices.

I don't know but it has charged anything I have connected it to. It charges quite fast. No complaints.

Sure but not fast. Better than a float charger but not like a 10 amp or larger unit. Maybe overnight.

They each have a different charging rate. The NEW charger will charge within a matter of hrs. The other doesn't.

Considering the max current this thing can put out is 750 mA, Having data pins connected for fast charge will not make a difference

I'm sure it will charge it, but the charging speed was awful for every device I tried.

This won't even charge modern cellphones as fast as most car-chargers (or that type of USB output that you plug into the cigarette lighter) can do. RE: John Taylor's misleading answer.2.1amp standard for USB3.0 and newer USB2.0 * 5volt standard USB socket = 10.5 wattsThis product's 0.5 amp * 12v = 6wattsUSB3.1 in 2015-16 = 100 watts!!!!! Try to wait for charging products that accomodate USB3.1 if you can; it's a HUGE jump in wattage & e.g. my Galaxy Note2 (USB2.0) take 8+ hours to recharge; also expected in 2015-16 are 1080p 3D head-mounted micro-LED displays worn like sunglasses for <$500 (mass-consumer price range) that draw ANOTHER 7watts or so.

I use the bank to charge multiple devices at once too. I have found no real difference. I suggest you save the money and buy the older (bank) one. I still use mine daily and love it!!!

Same as any low end product. I got my charger in November, and my TABLET in July 2013. Its on overbite..slow "cold" mess.I sure hope no one else falls for this same false advertising..like I did.Just now seeing your question. No one has successfully used this, far as I see here..right now, July 26, 2014..
