CONCLUSION

   18.000mAh may sound like a large number to some people (although during our tests as expected we hit roughly 13.000-13.500mAh) but having used and reviewed power banks with battery capacities of up to 30.000mAh this is not what impressed us with the AL390 by Xtorm but rather as mentioned earlier the built-in AC 230v electrical socket. This for some weird reason is something we almost never see with similar products so we all feel it’s a great feature since it allows you to use pretty much any electronic device that doesn’t need more than 65W to operate. Of course the AL390 could be perfect had Xtorm placed a 5v/1.5A USB port instead of two 5v/2.4A ones (2x2.4A & 1x1.5A would be ideal) since they may just be too much for the rechargeable batteries used in many smartphones. We do realize that the AL390 was never ment to be used on a daily basis (much like most power banks) so that shouldn’t be an issue (besides fast charging is never a bad thing when your device is out of juice) but still it would certainly put the mind of many at ease. Finally a jump-start feature for cars although not very important still it would also be nice to see especially since there are plenty of such models available in the market today (that makes me wonder why Xtorm hasn’t released something similar to date).

   Over the last few years Xtorm has become quite popular in the EU (unfortunately their products are not available in the USA) since they make high quality products that perform extremely well due to the battery cells they use so naturally they retail higher than similar products by not so popular manufacturers. To be more specific the AL390 Laptop Power Bank currently retails for 137.99Euros inside the EU (Amazon.de) a price tag that places it right next to several other models that offer capacities up to 30.000mAh and the already mentioned jump start feature for cars. Overall quality may be far from identical so that’s always something to take into account but what really makes it stand out from them is the AC 230v electrical socket and since the AL390 never let us down during testing it gets our Golden Award.
