E-Lektron EL225-UHF Mobile Sound System Review
Just like the JAD38-B the EL225-UHF Mobile Sound System again by E-Lektron may not score high in terms of design but thanks to its massive power output of 300WRMS and its many features including a 7200mAh built-in rechargeable battery it's a far more versatile choice.
Compared to even just 3-4 years ago portable speakers have grown significantly in size and although there are still not that many in the market which are not considered really "portable" any more thanks to their massive power outputs these also happen to be the only ones that can effectively cover large areas (you don't throw a party in a small room right?). Speakers like the EXOS-9 by Aiwa (and other similar in size models for example by JBL, Ultimate Ears and Marshall) may combine medium size enclosures with impressive power output but for many people (especially professionals) the lack of several features (not applicable to all) like an integrated MP3 player, physical controls (not only via smartphone), FM radio, limited connectivity and even support for Karaoke (although far less popular) are deal breakers. The recently reviewed JAD38-B Digital Sound System by E-Lektron did offer all of the above (and then some) but the lack of an internal rechargeable battery severely limited its uses. Today under our "microscope" we have the EL225-UHF (810.490) Mobile Sound System again by E-Lektron which doesn't seem to be hindered by that rather significant detail.
