ChargeTech Portable Power Outlet 18000mAh Review
      #48300 - 07/17/15 08:02 PM

We've seen plenty of portable batteries that can charge smartphones and even large tablets, but most of them don't have enough power output to charge laptops. ChargeTech (rebranded from ChargeAll) has released a powerful battery that offers enough power to charge up your smartphone and tablet via two USB ports, and also has an 85W AC output for charging your laptop. The ChargeTech Portable Power Outlet comes in three capacities and with the increased capacity the battery's size increases as well. The ChargeTech comes in either black or white.

The ChargeTech Portable Power Outlet battery charger is bigger than most portable batteries we've seen. The battery comes in three capacities and sizes: small (12000mAh), large (18000mAh) and Extra (24000mAh). They have roughly the same design that comes in a power brick shape in black plastic housing or white plastic housing. The large model (reviewed here) measures 7.5 x 5.25 x 1 inches and weighs 1.4 pounds. The battery has all its ports on one side and the ports include two USB 2.4A output ports, an AC output port, a switch that turns on and off the AC output port. The battery has a power on/off button on the top of the battery that you can also use to check the battery power level indicated by four small LEDs above the button. The two USB ports also have LED lights around them and they light up when they're charging devices. There's also a red LED strip next to the AC power output port and it lights up when the AC port is in use. The battery has a recharge hole on a separate side and it comes with a proprietary 40W AC charger.

The ChargeTech Portable Power Outlet 18000mAh can charge all the devices you carry with you on the road. It's important to know its potentials and limitations before you commit to carrying the large battery. It can charge a smartphone, such as the iPhone 6/6 Plus, the Samsung Galaxy S6/S6 edge and the LG G4, several times over from empty to full. If you're going on a family trip and you have 3 or 4 phones to charge, the ChargeTech is more convenient as you can charge everything with one battery as opposed to everyone carrying a battery pack for each phone. The 18000mAh can charge an iPad Air 2 at least two full charges and it can also charge the new 12" MacBook with Retina Display 1.25 times from empty to full. So if you take the new MacBook or an Ultrabook on the road, the ChargeTech will come in very handy for long flights, long meetings and long road trip where you might be away from an outlet.

While you won't find many portable batteries on the market that can charge up laptops, you should also remember that the ChargeTech Portable Power Outlet 18000mAh has max AC output power of 85W. That should cover most Ultrabooks on the market including the MacBook Pro 13" Retina. However, it won't give the bigger laptops nearly as much power as it does the small ones like the 12" MacBook Retina. We tested the ChargeTech with the MacBook Pro 13" that was driving both the built-in display and a 27" Thunderbolt display, and found that the battery filled only about 40% of the laptop's power. Still that's quite impressive for a portable battery. If you're doing presentations on the road and running out of power, that extra 40% battery life will still come in very handy.

One very nice feature on the ChargeTech Portable Power Outlet 18000mAh is its fast recharging speed. Usually a battery with such a high capacity takes overnight charging. But the ChargeTech takes less than four hours to fill up from empty to full using the included proprietary charge. The package also includes international power outlet adapters.


The ChargeTech Portable Power Outlet 18000mAh is a beast in both the size and its functions. If you take a smartphone, a tablet and an Ultrabook or a MacBook on the road, the battery will handle charging all of them nicely. It charges phones and laptops in about 2-2.5 hours, but oddly it takes at least 4 hours to charge the iPad Air 2. We love how fast the battery recharges itself thanks to the powerful AC adapter and the fact that one battery can take care of charging all the phones in the family. It is large and heavier than most other batteries, and it's not designed to work with larger notebooks that require higher power output.

Editor's Ratings (1-5): 4
What's Hot: Beefy and can charge laptops, easy to use, can charge three devices at the same time.
What's Not: Large and a bit heavy for travel gear bags, doesn't fill up larger laptops.
