Essential for vacations, hikes and other outings far from any power outlet, external batteries come in sometimes gargantuan capacities. This is the case of the 27,000 mAh model from Jiga, unknown to the battalion, but in the spotlight among traders, which justifies us examining what it has under the hood.
Ergonomics
Unlike many competing batteries, Jiga's 27,000 mAh model does not rely on compactness. This model certainly has a high capacity, but at the cost of a frankly high weight – 380 g announced, 413 g according to our measurements – which corresponds more or less to that of a touchscreen tablet. The machine will not find its place in your pocket given its thickness of 35.1 cm and its dimensions of 154.9 x 75.9 mm. Suffice it to say that this is not a power bank accessory designed for long, connected days, but a model suitable for long outings far from any power outlet, or for those who have to charge many products.
A word on the design of the device… It is entirely covered in plastic with a textured front part, undoubtedly for an aesthetic rather than ergonomic purpose. Its edges are rounded and the soap effect awaits the user. However, be careful of falling: the front cover is not welded and it can separate from the rest of the battery in the event of an impact. The clumsy (of which we are one) will wisely favor batteries that are a little more solidly constructed.
Above the hood sits an ignition button under which five LEDs are visible. At this price level, Jiga does not include a screen in its product, but simple charging indicators – two-tone, please. Note that this button is used to trigger what constitutes the main asset of this battery, namely its flashlight function. All you need is a long press on this button to transform this product into an auxiliary lamp. We can therefore imagine taking this type of battery to a bivouac, for example, or during a hike.
Let's finish with the Jiga battery connectors. It includes two USB-A ports (outputs), one USB-C (input and output), but also a micro-USB for those who own products equipped with this now dated connection. The assembly is placed at the end of the battery on a contrasting panel (red), reinforcing the “flashlight” look of the battery.
Finally, the latter is supplied with a USB-A/USB-C cable of around thirty centimeters, not integrated into the body of the case. To fully charge the device, you don't have to be in a hurry since it only supports 18 W. So allow a whole night to stock up on electrons.
Points forts
-
Connectors for all tastes.
-
Enough to power several devices.
-
Fun lamp function…
Weak points
-
…more gadget.
-
Really high weight.
-
Capacity too far from the announced 27,000 mAh.
Conclusion
How does the rating work?
If Jiga manages to offer a gargantuan 27,000 mAh battery on paper, we think it's bold to recommend it. Between its actual capacity well below its promise, poor design quality and its high weight, it is difficult to seduce despite its nice “flashlight” option intended for backpackers.
