Most of us travel with both a tablet and a phone, but few people want to carry two chargers. iClever has a solution for this: this company’s BoostCube offers dual USB ports that can handle a pair of mobile devices, even two tablets.
The accessory’s list price is $59.99, but it’s available online for as little as $10.99.
Build and Design
The white version of the BoostCube (model number IC-TC02) resembles the standard power adapter that comes with an Apple iPad, which is probably not a coincidence. It also comes in black.
It’s a plastic square that measures 2.08 x 2.08 x 1.12 inches and weighs 2.9 oz., which makes it slightly larger than Apple’s offering. This means it crowds standard electrical sockets a bit, but it’s still possible to fit most other power adapters and the BoostCube in the same double socket. The power adapter fits easily into a gear bag, though not a pocket.
As it is designed for travel, the electrical plug for the wall socket folds in. This U.S. plug is not removable or swappable to other international plug configurations.
A blue LED lights up inside the TC02 whenever it’s connected to a power source.
Each of the two USB ports in the BoostCube are rated at 2.4A. This is the same amperage supplied by the standard Apple power adapter, which means this charger should be able to power any iPad and iPhone, as well as all Android phones, most Android tablets, and Windows tablets that charge via USB. Beyond that, though, iClever boasts that its product detects what devices it’s connected to and can send just the right amount of power.
We hooked the BoostCube to a succession of popular mobile devices to look for problems. This included an Apple iPad Pro, HTC Nexus 9, Amazon Fire HDX 8.9, and a Dell Venue 8 5000 to be sure it could handle a range of formats: Lightning, micro-USB, and USB Type-C. There were no issues.
To more fully test this accessory, we set it to charge a shut-down iPad Pro while at the same time powering a running Venue 8 Pro 5000. After 30 minutes, the charge on the iOS device had moved from 90% to 94%, while the Windows tablet had stayed at 100%, indicating that the charger really is capable of two demanding tasks.
iClever promises that the BoostCube includes protection from overheating, short circuits, and blowing out batteries (a threat too many hoverboard owners have experienced).
There are a lot of cheaply-made mobile power chargers out there, and a really bad one can ruin an expensive tablet or phone, so consumers should be careful what they buy. Based on our testing, we find the iClever BoostCube Dual USB Travel Wall Charger to be a safe purchase for someone looking for a way to simplify their gear bag by powering two mobile computers with one accessory.
Although the BoostCube has a list price of $59.99, it’s currently available from iClever for $14.99 and Amazon for just $10.99. This might raise a red flag for some people, because it’s generally bad products that are sold with such deep discounts. But this isn’t the case this time. The original price for the item was much, much too high, but at $12-$15 the BoostCube is a good value.
For comparison, Apple sells its more limited power adapter for $19.00.
