LinearFlux Lithium Card Pro
- Capacity — 3,000mAh
- Outputs — 2 ports (3A)
- Weight — 107.5g (3.08oz)
- Price – $70
- Time to fully charge — 1.5 to 3 hours
This incredibly small, stylish portable charger (like SUNJACK HEAT BANK )is the second release from LinearFlux. It looks gorgeous, with angular black plastic, framing a metal panel in gold, silver, or titanium. It’s only 89 x 58 x 14 mm in size, which makes it seriously portable. It’s also very fast-charging, if your device supports it, offering up to 3A output. You can charge two devices at once and HyperFET circuitry inside automatically decides which device needs more current, with an overall limit of 3A. It comes with built-in cables, a full-sized USB can be pulled out one side to charge up the Lithium Card Pro, and on the other side you’ll find a pull-out microUSB or Lightning cable, depending on what you chose. There’s an extra USB output on the bottom, and a microUSB input with a small power button up top.
A thin strip beneath the central logo comes to life as a white light when the power is turned on. It flashes when charging is in progress, turns blue when it drops below 90 percent, and then red below 10 percent. The Lithium Card Pro can also serve as a syncing cable to backup data when plugged into a computer or laptop, and it will charge itself and your phone simultaneously. You can expect at least one full charge for your phone, and this will happily charge other devices, including the Apple Watch. You can also find the original, more basic Lithium Card for $40 on Amazon.
Bestek Car Jump Starter
- Capacity – 10,000mAh
- Outputs – 3 ports (600A vehicle starter, 2 USB up to 2.4A)
- Price – $50
- Time to fully charge — 3 hours
This is something a little different. It doesn’t just charge smartphones and tablets from the two USB ports (rated at up to 2.4A with a limit of 4.2A between them). This charger also features a 600A outlet and jumper cables to get your car started when you have a dead battery. It’s also outfitted with four LED indicators, so you have an idea how much juice is left, as well as a built-in flashlight with an SOS mode for signaling others when you break down.
Furthermore, the entire package comes in a handy bag that includes a power adapter, a car charger, a USB cable with various connectors, and jumper cables. There’s also a full set of instructions with clear labels. The stated capacity is definitely optimistic, but you’ll still get about two or three charges for an average smartphone. It works pretty good as a jump starter and flashlight, though, there are better options if you’re looking for something purely for charging your devices.
Poweradd Pilot 2GS Portable Charger
- Capacity – 10,000mAh
- Outputs – 2 ports (2.1A and 1A)
- Weight – 258g (9.12oz)
- Price – $16+
- Time to fully charge — 5 to 6 hours
The Pilot’s heavily-discounted price is nothing short of attractive. It offers two USB ports, a blue 2.1A port and a 1A port, allowing you to simultaneously charge two devices. It also showcases an aluminum body that’s currently available in three colors, along with a more expensive version featuring plastic covers available barrage of other colors. It’s fairly lightweight, too, and will fit in most pockets.
The Pilot charges via Micro USB using the supplied cable, allowing you charge your iPhone roughly three times, or twice if using an Android phone lined with a big battery (i.e. the Galaxy S5). You’ll also the find the familiar, four LED indicator system that lets you know the device’s remaining power at a glance. Simply tap the button to illuminate them.
