Charmast 26,800mAH Extremely-Slim Energy Financial institution

Backside Line

At 26,800 mAh, the Charmast is the most important capability energy financial institution we examined and considered one of our favorites. We had been pleasantly stunned to see it ceaselessly beat out smaller-capacity energy banks in areas equivalent to weight, effectivity, portability, and sturdiness. On backpacking journeys, we frequently discovered ourselves reaching for this financial institution over lots of the different high-capacity energy banks and are impressed by its skinny, glossy design. 

Some notable wins for this energy financial institution embrace its low weight and that it is likely one of the best battery packs we examined. The Charmast 26800 packs a number of energy in each ounce. Along with its base options, we discover it simple to make use of. It sports activities three enter and 4 output ports, permitting most flexibility. One of many output ports helps fast charging, and this energy financial institution routinely initiates trickle charging for small electronics. For backpackers on the lookout for probably the most energy in one of many best-designed banks, look no additional!

Effectivity

Not solely is it the lightest large-capacity energy financial institution, however the Charmast can be probably the most environment friendly. This shouldn’t come as an enormous shock: being each the lightest and the very best capability in our lineup, it ought to supply loads of charging energy for each ounce of weight. Nonetheless, energy banks are infamous for having much less energy out there than is listed on the packaging, so we needed to ensure. To check this, we used a multimeter and dummy resistor load to empty the battery whereas concurrently recording the facility output. After a number of calculations, we confirmed that the Charmast is probably the most environment friendly large-capacity energy financial institution we examined.

Weight & Packability

Given the appreciable energy capability of the Charmast, it’s surprisingly light-weight. Don’t get us mistaken; it weighs greater than any of the small-capacity energy banks we examined. Nonetheless, when positioned on our scale, it was the lightest battery pack with over 20,000 mAh of energy. That is a powerful feat, significantly contemplating it beat out two energy banks that had been 6,800 mAh smaller. We additionally admire that it was lighter on our scale than the listed specification. Amazon lists the burden as 14.9 ounces, and different sources checklist it as 15.2, however our measurements confirmed it was round 12 ounces.

Huge batteries are inclined to take up plenty of house, however the skinny profile of the Charmast makes it simple to hold. We had been curious how the completely different shapes of the large-capacity energy banks we examined would influence portability. On one aspect, we’ve got the Charmast, which may be very skinny however compensates as a pancake would- by spreading out extra. Others are thicker however not so broad or are formed like bricks. To reply this query, we measured the size, width, and peak of each energy financial institution we examined to search out the whole quantity.

We found that the Charmast has one of many smallest complete volumes of our large-capacity battery packs. It feels extra streamlined, and the slimmer design provides an additional sense of being lighter than it’s. All of it comes right down to choice and the place a consumer needs to put the financial institution. The Charmast performs higher in skinny however vast areas equivalent to tent aspect pockets, whereas others match higher into pants pockets. Given its measurement, the Charmast did effectively on this class.

Sturdiness

Except for some minor beauty injury, the Charmast stood up fantastically to the whole lot we threw at it, together with being dropped and jumbled within the backcountry. Like lots of the energy banks we examined, the Charmast has an outer coating that simply scratches. The abrasions on our mannequin occurred primarily from being carried free in a bag filled with different energy banks and from our drop take a look at. Customers must be conscious that sliding off of a rock or different common use will trigger some put on over time. Fortuitously, this didn’t have an effect on the integrity of the Charmast, and it nonetheless charged gadgets after passing our eight-foot drop take a look at.

Charging Pace

The most important weak spot of the Charmast is the period of time it takes to recharge. Throughout our exams, it took longer than some other energy financial institution to recharge, simply shy of seven hours. Even different large-capacity energy banks carried out a lot better on this class – some ending half-hour earlier. That point can add up when resupplying in cities or attempting to get out the door on a last-minute journey.

Options

One of many nice issues a couple of bigger energy financial institution is room for extra options, which the Charmast has loads of. A function that units it aside is having three enter and 4 output ports. This supplies many choices must you lose a charging cable or have to cost a number of gadgets concurrently. Like most energy banks, the Charmast permits for pass-through charging, which implies that a tool might be charged off the facility financial institution whereas the financial institution itself is being charged. This energy financial institution additionally has a fast cost port to cost telephones quicker and may acknowledge when a low present is required for smaller electronics. All in all, there are many usable options!

Chilly Charging

The Charmast has many strengths, however efficiency in chilly temperatures just isn’t considered one of them. As backpackers who hit the paths year-round, we all know how essential cold-weather efficiency is within the shoulder seasons and winter. When the times are brief and the nights are lengthy, it’s arduous to keep away from chilly temperatures when needing to recharge electronics. To check for this, we drained every take a look at financial institution once more utilizing our multimeter and dummy resistor load, however this time, we positioned the entire setup inside a fridge. We had been disenchanted to see that the Charmast misplaced 6.7% of its complete output in chilly temperatures in comparison with its efficiency at room temperature. It isn’t its most shining second, however it isn’t the whole finish of the world so long as some precautions are taken on the path.
