CONCLUSION

   Before we start with our conclusion i would like to point out that the AL420 was not designed and manufactured to withstand water pressure and so although it is virtually waterproof we don't suggest submerging it. We did submerge inside a 30cm deep plastic box we have here for such tests and it still works but i really recommend against it. With that out of the way we all liked the build quality and design of the Xtreme Power Bank AL420 since not only is it durable but it looks nice and is also quite compact. As expected after 7 full charge cycles the available battery capacity did not hit the advertised 9000mAh but we did squeeze roughly 6000-6200mAh out of it and as we've pointed out in the past numerous times that's always the case with portable batteries (power banks). The built-in LED torch/flashlight is a fine addition and although it will not light up a room it can certainly come in handy (we haven't really seen however a more powerful one in a small power bank). Now we'd all like to see a second USB port with the AL420 for simultaneous charging of two mobile devices since its size allows for one but for some strange reason Xtorm didn't do so.

   Once again we were unable to locate this product by Xtorm inside the USA so if you live there chances are you'll need to buy it from elsewhere. Inside the EU however the Xtreme Power Bank AL420 is widely available and currently retails for just 51.99Euros inside the EU from Amazon.de. This price is one of the best on the internet as we speak and it's also very balanced considering that you're getting a rugged power bank with a 9000mAh rechargeable lithium-ion battery inside. Sure there are several power banks with highest capacities at around the same price range but certainly not rugged and not of the same high quality which is why the Xtorm AL420 Waterproof Power Bank Xtreme 9000mAh gets our Golden Award.
