Travel bans be damned—portable devices are part of the way we travel. Odds are your carry on bag is just one merino shirt, some jorts, two pair of travel underwear, and a rat’s nest of cables, chargers, cases, and gizmos. Whether you’re a freelancer, a writer, travel videographer, a digital nomad, or a rising travel Instagram star, your bag includes at least one smartphone, laptop, camera, GoPro, iPad, or Kindle—and the cables that come along with them. The point is, we travel with a lot of tech, so a good external battery pack has increasingly become a must-have for today’s modern carry on traveler.
But which portable battery chargers is the best? Which one packs the most charge for the price (or the weight)? Evaluating your next portable battery charger isn’t rocket science. We looked at charging times, charging speed, charging capacity (mAh), weight, durability, water-resistance, multi-functionality (is the battery charger also a flashlight, for instance), and of course price to bring you our comprehensive list of the best external battery chargers for your next off the grid adventure. Get amped (see what I did there?).
Luggage with Built in Battery Packs
If you’re a bag geek at all you’ve been watching the trend towards “smart luggage” and bags with built in battery packs. On the surface this does seem smart, doesn’t it? Especially if you’ve ever spent your airport layover jockeying for a position at the one plug in your terminal instead of sipping a bloody mary at the airport bar. The ease and convenience of a piece of carry on luggage that is also your juice box is alluring. Until you actually think about it.
The names of the game in carry on travel are size and weight, right? Certain dimensions within which all bags must fit and a certain amount of weight that is allowable. The weight restrictions vary between 12.5 lbs to unlimited, averaging around 25 lbs. So, if your bag weighs about a third to half of your allowable carry on weight before you even pack it, that’s kind of a problem.
A quick search of carry on smart luggage turns up a number of Indiegogo and Kickstarter campaign babies that look sexy at first blush. Until you read the stats and consider the implications. Away is over seven pounds. Bluesmart tops nine. And of course they’re both wheeled luggage, which we already know could ruin your trip. Also, these bags are really friggin’ expensive.
The offerings in the backpack category aren’t meant as actual luggage. They’re actually daypacks. Here’s the thing about a daypack: You have to carry it. A lot. With stuff in it. Why, would you begin with an empty bag that is heavy? The Outbreaker travel daypack weighs 1.1 lbs. The lightest contender among the leaders with a built in charger is double the weight of our bag, the heaviest tips the scales at nearly five times the weight of Outbreaker daypack. So you could carry the heavy RAVPower 26,800 mAh beast that weighs just over a pound and still be lighter than the lightest “smart backpack.” Oh, and of course you’d have the option of NOT carrying it. That’s a detail. I don’t know about you, but I don’t want to be forced to carry extra weight built into my bag.
Of course the other factor that no one is talking about is that these battery packs become obsolete in no time flat. Remember what you were carrying for external power two years ago? How ’bout five? That’s what I thought. How long do you expect your luggage to last? Yeah. That’s a problem, isn’t it?
Here’s the thing: When a piece of luggage tries to do too many things, it ends up doing nothing well. Choose the best possible luggage for urban travel (because that’s what you’re doing) and then choose the best possible battery pack for your needs and budget. No need to spend a fortune. Then, upgrade when it makes sense.
Now that we’ve agreed not to buy smart luggage, here are the best options:
The Best External Battery Packs
Hands down, the most important metric when it comes to choosing an external battery pack is mAh (milli-Ampere-hours). Without getting too technical, the mAh is the amount of time your device can run under a certain current. The higher the mAh, the longer your battery will last. To give you a quick frame of reference here’s a chart showing the mAh of the most common smartphones.
If you have an iPhone 6s (1715 mAh), any battery pack over 2000 mAh will give you at least one full recharge. Easy peasy. There are a ton of other factors like discharge speed (1A vs 1.5 A or even 2A), but this isn’t a super techy review. I focus on capacity, functionality, and how you’re going to use these battery packs on the road. If you want to geek out on charging specs and features, read this deep dive into battery pack tech and specs from The Wirecutter. Those guys know their stuff.
Now that you have some idea what you’re working with, let’s dive into some of the best external battery packs on the market and see which ones are best for your hiking trip, everyday use, European vacation, and life on the road as a working digital nomad.
Most Powerful Portable Battery Chargers
Anker Power Core mAh 20,000 — $39
One of the most powerful pocket chargers available under $50, the Anker Power Core is a solid purchase for any tech heavy traveler or digital nomad that needs to get work DONE. At 13 oz. it’s at the top end of pocket portability, but the dual 2A outputs guarantee a fast charge. One of the best battery packs for your buck from one of the most trusted names in external battery packs in the industry. I prefer this battery over the Anker 26800 mAh ($60) because the added mAh isn’t worth the extra bulk.
RAVPower 26800 mAh — $50
This external battery is a straight up workhorse. Fully loaded with 3 USB outputs, including a 2.4A port (that’s super fast), this is the go to digital nomad external battery pack. This battery can charge in sleep mode, carry a full charge for nine days, and charge multiple devices at once. It weighs in at just over a pound, but it’s great for heavy users on the go.
Aukey 30,000 mAh — $49
Another tank like option for heavy users on the go, the Aukey features an extra charging port (4 vs. the RAVPower’s 3), and has a lot of similar specs including weight (20 oz.) and 2.4A output. A great choice for gamers on the move, this bad boy features a USB C charger (for laptops) and can even charge a Nintendo Switch in a few hours.
Best Budget Portable Battery Charger
The best budget chargers also tend to be the lightest chargers, so I don’t want to double up this category. However, the PNY 2200 is worth mentioning for the price tag alone.
PNY 2200 (mAh 2200) — $7.65
One input, one output, one charge. Portability, simplicity, and a full charge is way more than you should expect from an $8 external battery charger, but there you are. Delivering just what you need when you need it. Perfect for weekend trips, long flights, or just keeping in your bag for emergencies.
Lightest USB External Battery Chargers
TravelCard Charger 1500 mAh — $29
This modern marvel is only 5mm thick, and weighs less than 2 oz. Even better, it’s got the charging cable built into the battery! Seriously, this is the ultimate get out of jail free battery charger. Perfect for business travelers and digital nomads, you can toss this in your wallet or that little zipper of your daybag and forget about it until you need it.
While 1500 mAh isn’t a ton of charge, it’s enough when you need a little boost. Plus, features like “pass through charging” (you can charge the battery pack and a phone at the same time), make this cheap, light, extremely travel friendly external battery pack a fantastic choice for frequent travelers.
Flux Charger 4000 mAh — $29
The natural predecessor to the TravelCard, the Flux charger is a tad heavier than the TravelCard (3 oz.), but packs more than twice the charge. With a lot of the same features—pass through charging, built-in charging cables—and the same price tag as the TravelCard, the Flux gives you a little more bang for your buck. It can charge a dead iphone to 100% in about an hour, so that’s sweet.
The Flux Charger Plus (10000 mAh — $50) even features a USB C adaptor ($8) so you can even charge your laptop off of it. That’s game changing.
Anker PowerCore+ “Lipstick” Mini (3350 mAh) — $14
There’s a reason this is one of the best selling portable battery chargers on Amazon—it’s insanely portable. This little workhorse can charge any phone on the market (at least once), and it weighs less than 3 ounces.
While I don’t recommend this for heavy travel usage abroad—one charge isn’t really that much—the shape, smooth metal finish, and streamlined utility make this charger one of the few that I recommend for everyday carry. Toss this in your bag, backpack, or purse and rest assured that you’ll never run out of battery on your phone again.
If you want to scale up from the Powercore Mini, here’s a full list of Anker chargers with all the specs:
Lepow 10000 mAh — $34
The sleek design and super pleasing hand feel of this charger is worth the price alone, however it’s worth noting any charger that delivers 10000 mAh for just $34. This portable charger is jam packed with features like 2.1A output (that’s fast charging) and slide and shake design to see how much charge is left in your pack. Everything about this charger is thoughtfully designed, down to the woolen felt pouch.
Most Rugged Portable Battery Chargers
Nomad PowerPack (9000 mAh) — $119
Built with military grade drop protection, a dual layered chassis, and even Tile integration (the bluetooth function that lets you find lost items), this battery charger can take a beating and come back for more.
9000 mAh of charge in a portable package, the Nomad charger features 2A output charging, and USB-C compatibility, meaning that’s it’s faster than your iPhone wall charger, and it can charge your laptop. Sold.
Outdoor Tech Kodiak Mini 2.0 Charger (2600 mAh) — $25
Perfectly priced at $25, this little portable battery charger is a little low on the juice end of the spectrum (it can charge an iPhone 1.5 times on one charge), but it makes up for it in portability, durability, and straight up style. Waterproof and rugged, it even features external lights to make you visible on the trail. Choose from 4 vibrant colors.
Braven BRV Bank 6000 mAh — $129
This IPX5 water-resistant battery charger is great for long hikes and river trips. Rugged and full of beans, the bluetooth function on this charger is a tad confusing. You can monitor the battery life through an app, but that just drains more battery. Also, the last thing I want on a river trip is my phone. Still, it features a built-in flashlight and different modes including “Bear mode” which sends your battery pack into a blinking shrieking frenzy. So that’s amazing. Plus it can charge your gear for days in the wild.
Most Versatile Portable Battery Chargers
MAXOAK 50,000 mAh — $136
In the immortal words of Mr. Samuel L. Jackson, “Hold onto your butts.” This beast of an external battery pack has everything—literally.
Featuring six output ports:
- 20V/3A for Laptops
- 12V/2.5A for Digital Cameras
- (2) 5V/2.1A
- (2) 5V/1A For Most of Smart Phones, iPad, Tablet and More USB-Charged Devices
Be a hero and charge every single device in the entire hostel. At once. The K2 battery pack also recharges in 6-8 hours, so you can juice back up overnight.
This is an extreme portable battery charging option, but it’s honestly not that crazy for professional digital nomads going off the grid for a while—especially for the price. 50000 mAh is absolutely top of the charging curve, and the ability to charge a laptop on a portable charger is a big deal (check to make sure your laptop is compatible). The whole rig weighs less than 3 lbs, which is right on the edge of actual portability, so I doubt I’d ever use this beast, but it’s nice to know it’s out there.
Maybe if I was organizing a music festival, or working in the Christmas tree stand again this year.
Powerall Supreme 16000 mAh — $109
This surprisingly versatile portable battery charger is the perfect emergency charging gear for your next car camping weekend. The 16000 mAh capacity is enough to charge your phone or GoPro several times over, but the clamps and jumper cables actually make this one of the few portable batteries that can recharge your most important device—your car.
Equipped with a LED powerful flashlight, a strobe light, and even an SOS light sequence, this is the ultimate car camping/emergency charging battery. Seriously, one charge holds enough power to jump start your car 20 times. Chuck this in the glove box and sleep a little easier on your next road trip. It really does “power all.”
MyCharge HubMax 10050 mAh — $67
This little portable charger is the swiss army knife of external battery packs. The built-in Lightning and micro USB cables are nice (you don’t have to carry those tangly bastards), but the really slick feature is the built-in wall prongs right on the battery. This interesting design of this portable battery pack means that don’t have to daisy chain a million adaptors, chargers, and cables together. You just plug and charge.
Tylt Energy 5k 5200 mAh — $37
Similar to the HubMax, the Tylt ENERGY charger features onboard lightning and micro USB charging cables. It packs about half the punch as the HubMax, but it’s half the price half an inch thick, and weighs just over 4 ounces.
Carved Wooden Power Bank 6000 mAh — $50
Not all portable battery packs have to look like discarded robot nuggets. The 6000 mAh battery charger from Carved features a case made from real wood. Seriously. The battery packs are beautiful, functional, and customizable. Take a peek at some of their incredible designs and set your battery charger apart from the sheeple at your local coffee shop.
Best External Battery Phone Case
Mophie Juice Pack Air 2750 mAh — $49
I was never a huge fan of external battery phone cases until I drove across India in a rickshaw. My buddy Jarrod slapped a Mophie Juice Pack on his iPhone 7, and it might have been the star of the trip. We abused his phone. We bumped tunes off it all day while we drove. We used it for GPS, maps, and directions. We booked accommodation on it, kept in touch with others via WhatsApp, and shot a ton of photos and video on it throughout the day. Oh yeah, and Jarrod “worked” on it, or whatever.
That single external battery phone case powered our trip. No matter how much we used it, we never ran out of battery. It got to the point where I almost expected my phone to keep up with this supercharged beast.
The Mophie case adds 27 hours of battery life to the iPhone 7 (more than you need), and even allows for wireless charging (if you’re fancy). The phone case does make your phone a bit heavier (2.6 oz.), but the added battery life is insane, and you get used to the solidity of your phone.
Bottomline: if you’re only bringing an external battery pack to charge your phone, cut out the middleman and get a battery case.
External battery packs are just part of the way we travel. Whether you’re a digital nomad, a freelancer on the go, or an Instagram superstar, keep one of these portable battery packs in your bag and be prepared for anything.
- mAh are the most important measure of a portable battery pack
- 2A charging means faster charging, but only if your phone can handle it (iPhone peak charging is 1.5A)
- More outlets mean more options — two is way better than one
- Durability matters, get a battery pack that can take a hit
