Portable chargers are nice. They don't quite make up for phones with crappy battery life, but they come close. Plus they bring the peace of mind that comes from knowing you won't be tethered to a wall if your phone decides it won't make it through the evening.
You can grab one at full price, but the reason you're reading this is so that you don't have to. So let's cut straight to the chase.
You could say external battery packs are the AA batteries of our times. They breathe life into your phone during an emergency, and some even come with a flashlight built-in. Such is the case with the RAVPower 16,750mAh portable charger that is currently Amazon's deal of the day.
Portable batteries are great for juicing up your gadgets when away from a power outlet. The problem is, most battery powered chargers deliver electrons at a snail's pace. Fortunately, thanks to Qualcomm Quick Charge 2.0 technology, there's a new crop of batteries that are both portable and fast. One of the better ones is Aukey's 10,400mAh battery, and right now you can pick one up for $20, a third less than the normal price.
Besides QC 2.0 technology, there isn't a lot to be said about the battery. It has one USB port, four LED charge level indicators, and a nice rounded aluminium shell.
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.
Do you find that your devices constantly need more juice while you're out and about? There's a good solution for that quandary: a portable charger. As a day-one Verizon Galaxy Nexus owner, I quickly learned how important always having one with me is, and now I never leave home without one (even though the N4 is extremely battery efficient by comparison). If you're in the market for just such a charger, Amazon has a couple of good deals going right now for EasyAcc's 10k and 12k mAh chargers, at $28 and $37 respectively.
The 10k mAh charger houses two USB ports – one for 2A output, and the other for 1A (both at 5V).
Riddle me this: what is better than one big honkin' external battery? Yes, two big honkin' external batteries. If you head over to Amazon right now, you can get two New Trent batteries at quite a discount. In this age of non-removable smartphone batteries, how can you lose?
All you have to do is add the New Trent iCarrier and iGeek batteries to your cart. Then use the coupon code J8F6EA63, and you'll get the $59.95 iGeek for (almost) free. The iCarrier sells for $76.95 and has a 12,000mAh capacity. The iGeek is smaller and more portable, but still packs 9,900mAh of juice.
At this point, we've covered the benefits of having a portable charger/battery pack so much that you probably have all the reasons to buy one engrained in your memory. If you still haven't invested in one (or need to upgrade), however, tech.woot has a pretty solid deal on a couple of chargers from uNu.
The 5,000mAh Enerpak Tube is going for a mere $34, while its larger brother – the 11,000mAh Enerpak Vault – is available for $50. Considering the latter is pushing $80 on Amazon, those are both solid deals.
Both chargers feature a 5V 1A input and 5V 1A output, but the Vault also has a larger 5V 2.1A output for charging more power-hungry devices like tablets.
Do you feel drained of energy after a long trip? Imagine how your devices feel. Woot might be able to help out with their pain and suffering. Today only, Wooters can get the Powerbag Instant Messenger and Powerbag Sling for just $39.99 each. David gave the Instant Messenger very high marks in his review, and we know that he and Aaron use this bag in their day-to-day activities.
Note: There are inconsistencies about pocket sizes between the manufacturer website and Woot. I'm taking these numbers from the manufacturer.
Having multiple devices that need to stay juiced up while you're out and about means that a portable charger should be a standard part of your on-the-go gear. If you don't already have one – or are in the market for a new one – Daily Steals has quite the deal going on a massive 9000mAh battery pack that can charge up to four devices at the same time.
The primary thing that sets this charger apart from comparable units (aside from being able to handle four devices at once) is that it actually has built-in microUSB and iPhone 30-pin connectors, so you don't have to carry extra cables with you.
