TOP 5 PORTABLE BATTERY CHARGERS
1. RAVPower Universal Power Bank Travel Charger
Capacity — 27,000mAh
Outputs — 4 ports (1 AC at 100W 0.9A, 1 Type-C at 3A, 2 USB at 2.4A each)
Weight — 861g (30.4oz)
Price – $170
When you absolutely, positively gotta charge every device in the room, accept no substitutes. It’s debatable whether this is really portable, but the extra size allows an unbeatable 27,000mAh capacity and offers something that none of the other power banks in our list can — an AC outlet. You could plug a TV into this, but a laptop seems more likely and it will charge up the new 12-inch MacBook three times over. For phones it can charge up an iPhone 6S more than 10 times and a Galaxy S7 around 6 times.
In addition to the 100W/0.9A AC outlet it also sports a Type-C port that can output at 3A, along with two traditional USB ports offering up to 2.4A each. You could charge a MacBook and two phones at once if you want to. You’ll find a standard LED array in blue to show remaining power, but there are 8 LEDs instead of the usual 4. It also has a DC input at 19V/1.6A to recharge faster, though it’s still going to take a few hours.
This thing is pretty huge and heavy, but it’s a versatile beast and it has vents to prevent overheating. It ships with two Micro USB cables (one short and one longer), a power adapter, and a travel pouch.
2. Maxoak Power Bank
Capacity — 50,000mAh
Outputs — 6 ports (1 V20 at 3A, 1 V12 at 2.5A, 2 USB at 2.1A, 2 USB at 1A)
Weight — 1.26kg (2.77lb)
Price — $136
Time to fully charge — 6 to 8 hours
This is the biggest option on our list, and it stretches the term “portable” to its breaking point. But if you need a versatile solution that will charge your laptop, digital camera, and smartphone, then Maxoak’s offering might be perfect for you. All the ports are located at one end, along with an oversized power button and a four LED array that gives you a rough idea regarding the device’s remaining power.
The charger is cumbersome and not exactly pretty, but its capacity is robust. You can charge an iPhone 7 Plus or a Samsung Galaxy S7 Edge more than 10 times with this external battery pack. You also get a smorgasbord of different connectors with it — 11 in total — allowing you to connect to a wide variety of laptops and notebooks. We suggest checking compatibility before you buy, however, because it does have some limitations.
If you want to charge multiple devices at once, the Maxoak Power Bank can do it. There’s also support for pass-through charging, meaning you can charge a host of devices while fueling the charger itself. It comes with a power brick and cable, too, which charges rather quickly considering the capacity. You even get a bag with a zipper and a pocket for the adapters.
3. ZeroLemon ToughJuice Rugged Portable Charger
Capacity – 30,000mAh
Outputs — 4 ports (2 x 2A and 2 x 1A)
Weight — 400g (14.1oz)
Price – $68+
Time to fully charge — 8 to 24 hours
If you want enough power to keep your gadgets going for a week in the wilderness, then this rugged power bank from ZeroLemon could be right up your street. It’s very big and heavy, but that’s the price you pay for a 30,000mAh capacity. It’s also designed to cope with the outdoors, so there’s a dual-layer plastic covering to absorb shock and port covers to keep dirt out, but it won’t cope with the wet.
It’s capable of charging up four devices simultaneously with a combined output of 6A divided into 2A/2A/1A/1A. You’ll be able to charge up an iPhone 6 or 6S around ten times, a Galaxy S6 about seven times, or an iPad Air a couple of times. There’s a round power button on the top with four LEDs built in to give you an idea about the remaining power.
You only get one Micro USB cable in the box, but there are actually two Micro USB ports to enable you to charge this up faster, which is a good thing, because it can take 24 hours to charge with a single charger. It’s not going to suit everyone, but for a family or a group of friends on a camping trip, this could be ideal.
4. iBattz Mojo Battstation Optimus Charger
Capacity — 20,400mAh
Output — 2 ports (2.1A and 1A)
Weight — 400g (14.11oz)
Price – $76+
Time to fully charge — 15 to 16 hours
If you need a lot of juice then this 20,400mAh-rated battery charger has more to offer than just a silly name. You’ll get multiple smartphone charges from this thing, it’ll even fill up an iPad with plenty of power left over. It’s heavy, but it’s smaller than you might expect, considering the capacity, and it has a nice soft-touch rubber finish in black with an orange highlight.
There’s a USB port at either end, and the spine plays host to the microUSB port for charging it up, the power button, and the built-in flashlight. It’s a slightly odd arrangement. It also comes with a 2A charger, a microUSB cable, a 30-pin adapter for Apple devices, and a Galaxy Tab connector. You can charge two devices at once, but you might not get the full advertised speeds. The downfall with this is the slow charging time for the charger itself, but it does deliver a lot of power at a pretty reasonable price tag, and the design is good.
5. Anker PowerCore 20,000
Capacity — 20,000mAh
Outputs — 2 ports (QC 3.0 2.4A and 2.4A)
Weight — 368g (13oz)
Price – $45
Time to fully charge — around 8 hours
Support for Qualcomm’s Quick Charge 3.0 standard means that this power bank can charge up a supported smartphone to around 85 percent in just 35 minutes. Sadly, there aren’t many QC 3.0 phones right now, but it is also backwards compatible with earlier QC standards, so you’ll get the fastest possible charging speed regardless of what phone you have. The second port can top out at 2.4A and has Power IQ to determine what speed to charge your device at.
This is an impressively compact device considering the monstrous capacity, but it’s not something you’d slip in a pocket — it’s a bit too big for that. Anker has encased the battery in a rounded polycarbonate body that’s comfortable to hold and it’s also fire resistant and tested for impact, vibration, and extreme temperature.
The capacity is more than enough for any trip. You’ll get five full charges for a Galaxy S7 out of this and it’ll even charge most tablets twice over. You get a Micro USB cable in the box with it and a handy travel pouch.
