Effectivity
Among the many 10,000 mAh energy banks we examined, the OKZU is barely above common relating to the quantity of energy per ounce and whole output. It additionally scores simply above common for effectivity in comparison with all the ability banks we examined. We gathered these findings by plugging the totally charged OKZU right into a multimeter and a dummy resistor load, which persistently drew energy from the financial institution. By evaluating the overall quantity of energy contained in the financial institution to its weight, we might higher perceive how massive of a punch these small batteries pack. Extra energy per weight means they’re extra environment friendly and a better option. The OKZU does an honest job on this division, significantly for these looking for a extra reasonably priced possibility.
Weight & Packability
The OKZU’s average weight is a good commerce contemplating its value and all-around efficiency. We measured it at 6.6 ounces, which is on par with the load marketed by the producer. After evaluating all the ability banks we examined, the OKZU’s weight places it in the midst of the pack when specializing in simply the ten,000 mAh capability vary. For comparability, the Nitecore NB10000 weighed 5.3 ounces on our scale. Weighing 1.3 ounces extra, the OKZU can prevent about $35. Unsurprisingly, it weighs considerably lower than the larger-capacity energy banks we examined.
Like many different efficiency areas, the OKZU runs above common by way of portability. We discovered it straightforward to carry and use, but it surely wasn’t our first selection of banks to seize. After finishing our measurement check, we discovered that it fell under common in comparison with different 10,000 mAh energy banks and barely above common out of all of the battery packs we examined. As it’s across the measurement of a smartphone, it’s sufficiently small to slot in a larger-sized fanny pack or hip belt pocket, but it surely could be a stretch for smaller hipbelt pockets. Total, it’s straightforward to make use of whereas out and about, but it surely isn’t our best choice.
Sturdiness
Functionally, the OKZU stands as much as the trials of the path, however cosmetically, it’s a totally different story. Our sturdiness checks consisted of a number of elements. To begin, we spent a number of weeks shifting the ability banks round in a loosely packed bag, the place they had been continuously jostled and banged collectively. We additionally introduced them on a number of backpacking journeys to check for regular put on and tear on the path.
Lastly, we carried out our drop check, dropping them from a top of eight ft into loosely packed filth. In any case of our testing, the OKZU nonetheless works like new. Nevertheless, by this level, a number of scratches are seen throughout its floor, giving it a well-worn look. Because it doesn’t include any protecting sleeve, there isn’t any method to restrict beauty put on and tear. In our expertise, performance is extra necessary than beauty look in a bit of substances like an influence financial institution, and it nonetheless carried out nicely general.
Charging Velocity
The OKZU 10000 smashes the competitors in charging pace. When plugged right into a QC 3.0 wall charger with a regular USB-C cable the OKZU was capable of totally cost in two hours and thirty-six minutes. This can be a full 40 minutes quicker than another energy financial institution. That point provides up, significantly when resupplying on the town on a thru-hike or preparing for the following weekend journey.
Options
The OKZU has simply the correct options for a budget-conscious choice to make it helpful within the discipline. We favored that it has each pass-through charging – which means you possibly can cost each the ability financial institution and a tool on the identical time – and the flexibility to cost a number of units concurrently. We additionally admire that it has two enter choices: a USB-C and micro-USB port. There isn’t any trickle cost possibility for smaller electronics, however general, it gives a stable variety of options contemplating its low price.
Chilly Charging
For these seeking to cost their units continuously in colder climate, there are higher decisions than the OKZU. After discharging it in a fridge utilizing our digital multimeter and dummy load resistor setup, we discovered it put out much less energy than throughout our preliminary effectivity check. In whole, this lack of effectivity added as much as a 6.9% loss, which put it in the direction of the underside of our checklist on this class. Luckily, workarounds embrace maintaining the ability financial institution heat inside a sleeping bag or beneath clothes for daytime charging.
