[US-Amazon] $6.99 Aukey 10,000mAh battery bank (add-on item)

[13CA350]

This aukey battery bank is 10K mAh and currently only $6.99 on Amazon. I haven't had experience with this particular unit- but I have used other cables and adapters from them. I've never been disappointed

I wouldn't trust this battery bank to deliver much compared to what it says it's rated for. My Anker 16000mah battery banks seem to lose 25% of their rated capacity from battery inefficiencies and stuff (because it is rated at 59.40 Wh but if I calculate from what it outputs, it should be 80Wh), so this should be an indicator. Plus that battery bank being so cheap should just be untrustworthy due to price.

Oh man, cheap battery banks. I've been drafting up another one of my awesome "cheap crap no one should buy" reviews for a while now on just this topic.

 

Back on topic though, a $60 bank on sale, with almost 90% off? Something smells fishy here lads, let's take this slowly.

A good 10k+mah should run you about 75-100 bucks. I custom built my battery back up bank and its running 100,800mah but cost me 300 to build, but i can jump start car, even run a car off it.

Go buy a single 3.7v 12600mah lipo cell and a 3.7v to 5v usb, cost you about 40 bucks max with making it look good, then there you go.

Although I agree that this probably isn't 10kmah, you should know that even high end Anker and other battery banks won't get 100% of what they are rated for. Some of the batteries power is lost through heat and other things.

Huh? That's something amazon does with almost everything. They put the regular price or list price at what the launch price was and never change it, so they can put xx% off all the time. Make more people likely to buy things because they think they're on sale. Nothing to do with this particular item. The scary thing shouldn't be the 90% off, but the only $7 part.

10kmah

 

As some one who teaches chemistry this made me twitch a little... It would just be 10Ah.  It sounds weird when you say kilo-mili-amps-hour.  They label it 10,000mAh for marketing reasons. Sorry... Was very bothered... Carry on.

Now I'd like to see both of those, do you have any links to the projects?  What do you do for charging them? What do you use them for?

Here hard a few pics of my battery pack. Let me explain how i have it all set up.

I use 8x3.7v 12600mah lipos each with a 100amp max 10sec discarge, rated at 20amp continuous current. I have those 8 cells wired 4s2p. So i pair up the cells in parallel which makes 4x3.7 26200mah cells. Then i run those 4 cells in series to make 14.8v x 26200mah cell capable of discharging at up to 200amps for 10 sec or 40amps continuously (plenty to run a car, or jump one)

Beacuse the battery sits at 14.8v it acts just like the electical in a car, so i have a high current plug on the battery, then i made lots of adapters:

Batt>car usb charger (dual 2.5 amp usbs)

Batt>jumper cables

Batt>prewired 400w ac converter

Batt>batt charger

Batt>12v led pods for my bike lights (pedal bike)

Batt>step down regulator

Batt>step up booster (this and step down is so i can have a fully portable regulated constant current and constant voltage power supply anywhere from 0-78v and 0-10amps)

Ill upload some pics as soon as i can. I dont have any on my phone atm

Ermm...no. I don't buy that at all. I bought a 10,000mah pack and it's just fine. It wasn't $100, it was $30.
