Update 10/12/15: New code below.
Each month this summer, the KMASHI 10,000mAh battery has become available for under $10 bucks. In June it hit $9.50. In July, it was $9.40. Now we're seeing it available for $9.29. All you have to do is head to the Amazon page and enter the coupon code
ME6ADK4L MHLSNM2R YTI7MT89 at checkout to drop the price down from its usual $14.
Yes, we all see what KMASHI is doing here, but we don't care. This is about saving money. This battery comes with two USB ports (5V / 2.1A and 5V / 1A) that can revive your dying smartphone when you're away from a charger. Read More
A couple of months ago, we shared with you a deal on Intocircuit's 11200mAh battery, which at the time was down to $13.49 after a coupon code on Amazon. Today, we have another external battery from the company, except it's the next generation one with better specs, more power, and a relatively great price of $14.99 after applying a $15 coupon code.
This dual-USB 13000mAh battery has SmartID technology, which allows it to detect the type of device connected to each of its two ports and channel the most efficient amount of power to it. It can go as high as 2.4A on each port, for a total of 4.8A. Read More
Until someone invents the fusion-powered backpack, there's no such thing as too much external power. And if you need some of that power on the cheap, there's a great deal on Amazon right now. You can get an UNU Superpak (with a capacity of 10,000mAh) for just $14.99 if you apply the coupon O66REVW3 when you check out. That's a solid $10-20 off of the going rate for these things, and $15 off of the retail price for the same unit. You can also grab free shipping if you've subscribed to Amazon Prime, which recently had its own significant discount. Read More
So you're at a gathering and your Android phone's about to die. Not only that, so is your friend's iPhone. Basically, in a few minutes, all the things will be dead. You could beg around for a couple of chargers, but then you'll have to trust that no one will take your device when you walk away or deal with being tethered to the wall until you have a reasonable charge.
This is when you want an external battery pack like the Choetech 15,600mAh one available on Amazon. The battery currently goes for $40, but if you enter the coupon code YDUKCSCX at checkout, you can take $8 off. Read More
You can never have too much battery power. Actually that's not true - strapping a Duralast to your back via some kind of shoulder rig so that you can play Crossy Road for 200 hours straight might be considered overkill. But any external battery that you can shove in your pocket for a long day of travel is a good one. If you're in the market, an Amazon vendor is offering a 16000mAh model (big enough for 4-5 charges of a current flagship) for just $23.99.
You'll need to use a coupon to get this discount (which also means that it's probably limited to the US version of Amazon). Read More
KMASHI's 10000mAh external battery charger is slim enough that you can carry it around in your pocket and charge your phone at the same time, as long as you aren't bothered by the prospect of walking around with a little bulge. Last month we saw it available on Amazon for $9.50 after a coupon code. Now it's back, and by entering JAK3JCUV at checkout, you can get it for $9.40 instead.
Yeah, a 10 cents difference isn't all that much. But keep in mind, we're talking about getting an external battery pack for under $10 bucks. Even if you don't need something slim, this is still a cheap way to recharge a modern smartphone three or four times before having to return to an outlet. Read More
Whoa, whoa! Before you load up that car and take off on your next vacation, sit down and take a look at this deal. On Amazon, you can currently get a 24W 4.8A 3-port USB car charger for $5. That's enough outlets for you, your spouse, and junior to all power your gadgets at the same time.
You have to enter the coupon code DDRQLCOL to bring the price down from $11. You have your choice of black and white.
What's that? Ah, you have three kids. That leaves two people without room to plug their gadgets in. For them, there's a 10000mAh power bank that you can get for $15.39. Read More
Are you looking for a ludicrous amount of external battery power? Then look no further than Woot.com today. The electronics section of the site is offering a two-for-one deal on a Limefuel 15000mAh external battery pack for $39.99. That's an almost ludicrous 30,000 milliamp-hours, approximately ten complete recharges of even huge phones like the Nexus 6. Also I guess you could keep one and give the other to someone else. Weirdo.
These particular batteries are pretty standard: they feature two charging ports each, 1 amp and 2.1 amps, plus an LED flashlight and a tiny LCD readout for viewing the battery level. Read More
If you have any use for a portable charger and don't have one yet, there just isn't any excuse at this point. Great deals are par for the course and this one is no different. Beating the price we saw a month ago, this external battery from Intocircuit has a massive 11,200 mAh capacity, a nice little screen to tell you what's what, supports 2.1A output to charge the most modern devices at a quick pace, and will cost you only $13.49 after coupon at Amazon.
As you might have noticed, this brick comes in two colors: silver and "gray." You might be thinking that those are nearly the same thing and you would be right. Read More
An external USB-powered battery is not a complex piece of electronics. Generally it has energy input, energy output via a couple of standard USB ports, maybe a few LED lights for measuring the charge, and perhaps a flashlight if the manufacturer is feeling creative. But today's Amazon Gold Box deal includes a battery that can actually start your car. How's that for flexibility? The Anker gadget (an economical brand name we've come to trust) is going for $59.99, $100 off the retail price.
Technically I suppose this is a car starter that can also charge your gadgets via two USB ports (1 and 2.1 amps, if you're wondering). Read More
