Peak input current for a Lii-202 using both channels at 1A was measured at ≈1.9A by HKJ in its review. If the supply can't provide enough current, the charger will just take what is available and charging time will lengthen accordingly.
Don't skimp on USB cables and take good care of them. Even some of the branded ones are a joke, with insufficient wire gauge to adequately meet the so claimed 2.4A current rating with ease. Longer cables need adequately bigger power wires gauge (twice the lenght means 3 AWG points less to maintain about equal power wire resistance). Also, twisted and/or bent plugs and your charging speed will plummet because of the much increased contact resistance and voltage drop.
Advantages: rated 3A, so it's quite likely it can do 2A even if a bit overspecced. Integrated cable means no added USB A male plug resistance.
Problems: its wire gauge seems too thin. If AWG24, even at just 3 feet long 316.602mV would drop in such cable when 2A of current flow through it, which is a lot considering we need to further add the drop in the USB micro B plug. If AWG22, it may do… barely. Some devices are picky with the voltage drop at the input and may quickly re-negotiate a lower current rate (slower charging). Potential fix: if AWG24, trim off half of the cable lenght. LoL!
The information Barkuti gave in the post above is excellent. :+1:
I also found the ones shown below at WalMart for $4.88 apiece.
They are ONN brand. They do preform to specs also. I use them.
You can read a bit more about them HERE and in preceding posts.
. ONN wall charger / 5V…2.1A
@teacher I went to the walmart website and put the model number in and it says the item is no longer available. Do you know anymore options safety/overload features is a plus? I’m trying to stay away from Ebay sellers. Do you know if cell phone usb will work?
I have not found them on the WalMart web site ever. I just go to the store and get them…. they have them at three I have been to.
If they don’t have them at your WM……………
Order that one from GearBest that Barkuti mentioned…… http://www.gearbest.com/chargers-cables/pp_488881.html
It would be an excellent one if HKJ gave his stamp of approval. :+1:
Cell phone one will work if it has the rating you need, or like he said will just slow things down if it doesn’t.
I called Walmart, they said they have them in stock. We’ll see when I go over the weekend. What does the usb plug does? My guess is regulate the amount current going to the device not sure if it does anything else. If the plug has to high volts or amps will it harm the device? Example Apple 12w usb plug.
When you apply for the PayPal account do you have to give a social security number?
The ubiquitous USB A female you usually see on (cough cough…) “chargers” is just a common interface. This way you can use the power supply for different devices/purposes by using the appropiate cable for whatever stuff: common USB A male to USB micro-B male/USB C male/Apple 30-pin male/Apple Lightning male/many others. These things are called chargers probably because of some confused moron's idea “in the beginning”. Most of them are pretty much USB voltage spec (5V ± 5%) power supplies. Only in recent times some newer models have appeared with multiple output voltages and more (Qualcomm Quickcharge and related @#$% stuff), though these will behave as standard 5V power supplies as long as there's no negotiation on their data lines.
The devices take care of how much power is taken and where it goes, no need to worry about stuff burning or pipebombs (unless you buy something wicked and out of specs, of course).
Cheers ^:)
P.S.: just had a good laugh checking the reviews of official Apple Lightning cables, I guess they deserve no less for selling junk at 8-10x its actual retail value.
Yep, they have them in the Electronics Department at the WalMart’s I go to.
Barkuti already answered the USB questions above this post.
No, you don’t have to give a SS # to open a PayPal account. I have had mine many years and can’t remember exactly what you do to open one. But I do remember it was real simple. You keep a credit card on file & a bank account to I think. And that is pretty much it if you are going to be Paying with the account.
There may be some other steps if you are going to be Receiving money…. I’m not sure. But the whole process is fairly simple and straight forward.

PayPal is just a payment intermediary, The Big Brother of Payments. When you pay with them, they just transfer the corresponding sale balance from your account to the seller's one, after substracting their fees. Of course, they watch over and have a hold on all of their customers' data. Their policies are, as far as I understand, picky and Conservative, and if you try to do something even remotely fishy, they may decide to withdraw your funds and suspend your account for as long as their investigation may need to. Forget about using PayPal for buying Bitcoins, research chemicals, etc.
Their currency conversion fees are outrageous (≈5%) and mandatory (in the past, you could select your card to be billed on the transaction's currency). @#$%!
I was just looking around at different charger and with the Samsung it said 25w and I didn't know what it meant. I was so used to seeing volt. I was looking around at different website and I can get that same charger without cable under $10. What I do like about that charger is the surge protection (not sure what it's called).Thanks for all the replies so far, much appreciated!
How much money is earned with those @#$% redirected links each time someone “punchs in”? Where are the fair-minded reviews/quotes behind these products, Pete7874? Not pretending to be rude, of course.
Hmmm, I am kinda mixed up about Barkuti is trying to say??
But could you put a link up to HKJ’s review of that one Pete…. I”d like to read about it. I”m on my phone right now & a search is difficult…… for me anyway.
