INTRODUCTION

   It may have taken slightly longer than expected but sales of portable batteries (power banks) all over the world have reached a point where even 3rd party manufacturers are also doing their best in order to take a piece of the pie. Because of that there are numerous backpacks (of all shapes and sizes), luggage, suitcases, jackets and even car and bike accessories currently available in the market featuring special compartments and/or pockets inside which you can place your power bank and use it to recharge your mobile devices while on the go. Power needs however have increased exponentially over the years and so even though a few years ago even a 6000mAh powerbank would be sufficient for most people today models between 12000mAh and 20000mAh hold the first spot in sales. Xtorm has released numerous impressive models over the years and since they too are aware of the increase in power needs they send us their latest Infinity 27000mAh model (XB203) to test.

   Xtorm was founded in 2008 and is part of the Dutch company Telco Accessories B.V., which has its head office in Houten (NL). Xtorm designs, manufactures and markets innovative universal mobile charging solutions. Xtorm Business products complement the range. Xtorm products are contemporary, user friendly and high quality. Xtorm products are currently available in 57 countries worldwide.

   As revealed by its name the Infinity XB203 model is among the highest capacity models manufactured to date by Xtorm since it's equipped with 26800mAh worth of A-grade lithium ion rechargeable cells. Even though however the Infinity 27000 packs enough juice to recharge even the highest-end tablets almost 3 full times (most high-end smartphones up to 6-7 times and even laptops up to 2 times) it's actually very compact measuring just 176mm in length, 105mm in width and 25.5mm in height with a weight of just 633g. Just like with previous models by Xtorm the Infinity 27000mAh also features their APM (Auto Power Management) and Auto-Temperature chips which help prevent both its internal lithium-ion cells and those of your mobile devices from overcharging and overheating. In terms of available connectors the Infinity 27000mAh has 3 USB 5V/2.4A ports (up to 3A) and a single USB type-C port all of which can deliver a total maximum output of 60W/6A (you can charge 4 devices simultenously). Unfortunately fast charging technologies like Qualcomm's Quick Charge are not supported by the Infinity 27000mAh but thanks to its 3A port charging times shouldn't be an issue for most modern smartphones.
