Need a decent dual 12v car charger for my work vehicle. Having two phones plus a tablet and laptop I'm juggling power outlets and need a fast charger.
Thinking about a scosche revolt dual charger. Has anyone got one of these?
I need to charge a Samsung tab. Sam sung galaxy mini and an LG phone

Why oh why isn't Anker here yet? Their US$7.99 dual charger is amazing.

Best luck I have had with a 2 port one is a tronsmart I got off aliexpress. One port is QC2.0 so it has to have separate regulators, not like the cheap crap that just has one conected to 2 sockets which leads to weird interactions between the devices as they both try to track the maximum power.

Oh boy you reminded me of Big Clive when you said that. DO NOT buy cheap chargers from AliExpress, even car ones. Most have no regard for safety so it is hit and miss.

Tronsmart is not a cheap brand. Probably similar to anker quality wise.

 

If someone picks the cheapest they can find on there then they will get a piece of crap, but them, aukey and a few others are actually decent, but they are about $10-12 instead of the 90c that the crap ones cost.

ive read in one of the other threads that the anker limited charge rates on some devices. i NEEEEEED to have the max possible charge rates for my samsung tab8 and galaxy5mini devices. dont want to take the risk with anker limiting to 490ma

I have had my anker 5 port wall charger do that on my note 3 and 4 many times, an unplug and replug often sorts it out, but its a hazard with those stupid auto detect chips that things have to allow non standards compliant iDevices to charge at full current.

oh and silly question , but why not just have a grunty 5v power supply to plug into??? is there something special about the usb charges that say a 3A capable 5v supply cant handle??

Anker make probably the best chargers on the market. If it rate limits a device it's going to be for a very good reason. There is a reason Anker are the #1 charger brand on Amazon - it's because they're currently making the best gear out there As to how long they'll be able to stay ahead is another story, and probably why they're diversifying into so many other products.

Android, no nothing special, just short the middle 2 pins on the USB so they know its a charger and not a computer.

 

Apple chose a different route and have resistors to signal what the max current of the charger is, instead of relying on it hitting its current limit and the phone figuring it out. That is why some crap apple chargers will blow up when you put an android phone on them and the phone trys to pull more than it can supply and the crap charger doesnt have a current limit, it just overheats or blows up.

 

The problem comes when you put an android on a charger with the resistors for apple and it doesnt go into charger mode because it doesnt ID it as a not computer.

Yes. The reason 99% of USB chargers and those in public places such as wall sockets and planes are crap is because they don't have any smarts in them. Most will only ever charge at 500mA tops.

 

Just compare the USB on the Air NZ IFE to my Anker battery pack. http://www.geekzone.co.nz/sbiddle/8900

Another thing that lots of chargers will do is increse voltage as current goes up to overcome cable losses, up to their current limit and then start to drop it down.

I have the Scosche Revolt (2x2.4A). Good reliable charger but never seemed to give max voltage to my smartphones (LG G3 and then LG G4 - both draw 1.8A from the wall but about 1.0A from the Scosche). I gather from reviews that it only reliably charges Apple gear at max rates. Some Android stuff will max it out, and some just won't. I think LG phones are unusually picky about chargers so you'd probably have more luck with Samsung gear.

 

When I got a G4 I bought an Aukey Quickcharge 2.0 charger instead, which is basically exactly the same as the Scosche but with the benefit of QC. Easier and cheaper to get too (Aliexpress). Amazon wouldn't ship the Scosche to me so I had to use Youshop.
