I've rarely had to "need" a high power charger.
At work and home(when I'm at my computer) I use
these cables. The "expensive" 15 foot long cable is less than $2 without shipping. The shorter cables are less than $1!
When in my vehicle I use
this genuine Motorola car charger for $7 on Amazon. I got it for free when I bought my phone, but at that price it can't be beat. Using some test equipment I was able to determine that the device outputs approximately 1.3A. If you want more than 1.3A you could buy
this 2.1A output car charger from monoprice for $8. Note that the charger provides a USB port. You'll need to buy a USB cable like the first link provided to connect it to your phone. I don't own one of these, but I'm sure it works great. When my phone dies, 5 minutes with the Motorola car charger and my phone is booted up waiting for me. I usually then walk inside the house and plug it into a USB port on a computer. I've actually had my phone die a few times before I got the extended battery. Just walked out to my vehicle and plugged it in for 5 minutes and watched it bootup. I learned the hard way that after the battery is dead a computer's USB port just don't cut it. One time it kept booting and shutting off for 45 minutes before I noticed what was going on. 5 minutes in my car and the phone was up and running.
If you plan to use your phone on an airplane for an extended time you can always use this
9000mAh battery backup! I don't own one, but I'd assume it can kick out some serious juice being that it's 9000mAh. Take that sucker on your airplane and you could easily watch 2 or 3 movies from your SDHC card and still have a full charge afterwards.
I have an extended battery now, and I've only let the battery go completely dead 3 times to help the phone calibrate the battery percentage. But between a car charger and a USB cable there's really no reason why you should have problems with a dead battery again.
If you somehow end up in a situation where you need more juice and you don't have easy access to a vehicle, then the battery backup above is for you. If you bought everything I listed above you'd spend less than $50!

Note: Some vehicles have USB ports built-in. My 2011 Ford Edge has 2 USB ports. I keep a spare cable for guests if their phone needs a charge on a trip. So far I haven't seen any built-in ports provide more than about 400mA of power. I expected this because the USB 2.0 specification calls out a maximum of 4 units of power for any USB device. 1 unit = 100mA.
Soo.. quit your beotchin' about power. There's so much power in this post we could build a Delorean and go Back to the Future! LOL. But seriously, I'm really not sure why so many people are always asking for high powered adapters. The ones I linked above are really cheap and work great. I haven't seen any chargers do more than 2.1A yet. But even then, with 2.1A of output you should be able to charge a typicall 1700-2000mAh battery from completely dead to fully charged in only an hour!
