Good value works well
Bought this to use with my Philips steam station for camping ,I got two nights of 10 hours sleep out of it ,perfect for w weekend camp . I forgot the little cable that joins it to my CPAP lady camp but used it to keep my heat pad going and charge my phone and other usb camping devices ,I would recommend ,shame the bag it comes in didn't allow for you to keep the right lead in it ,and shame it dosnt come with car charger .

Early days review - fantastic
I purchased this to provide power for dream station cpap on a flight. I wondered, would it last the night? Well it's so far on night 3 and has also powered the cpap in the day, just for the hell of it :) superb product if the battery keeps its charge over time. Oh, the cable included for the dream station works great.

Great product poor delivery
What a life saver this piece of equipment is. I use it for my CPAP machine while camping. It is just a shame about the missed delivery date and the courier not being able to meeting their end of the bargain.

CPAP camping aid!
Thought I’d give it a good test before writing a review. I bought this a couple of weeks ago to be able to take my CPAP machine when I go camping. Compared to batteries I’ve used in the past this is superb. I’ve had two continuous nights use out of it at home with about 4 hours left. It takes about 4 to 6 hours to fully charge, to be honest, I didn’t really time it. However, other batteries I’ve used in the past took about 12 to 14 hours to charge so by comparison Im happy. I don’t use a humidifier or heat tubes, probably important factors. It’s perfect for my needs and is light enough to carry in a rucksack. I recommend it.

Under promise and over deliver
I purchased this in preparation for a camping trip abroad next year. It was delivered on time, in very nice packaging with a carry case included. Once delivered I fully charged to test with my Philips Dreamstation to see A) would it last a full night and if so B) How long would it last on a full charge. The battery indicator is in the form of 5 bars (so approxiately 20% per bar). I was amazed to see on waking up after the first night (7 hours & 22 mins use) that it still had all 5 bars showing and therefore I'm guessing had used less than 20%. Important to note that I don't use any heating or humidifier, which I would guess would increase consumption significantly. After night 2 (7 hours & 57 mins use) it had 3 bars remaining, so I risked a 3rd night (7 hours & 12 mins use) and it still had a bar indicating on the battery the next morning. I'm not going to risk a 4th night, mainly because I should have access to charge each day when I'm away, so have tested to a worst case scenario for me and happy to report it passed with flying colours. Over 22 and a half hours use, with charge still left in the device. I'm a big fan of companies that under promise and over deliver rather than the other way around and Easylonger fall in to this category based on this experience and will definitely look at other products. If you're a CPAP user who may have the odd night where you don't have access to power, this is a great bit of kit and will come in handy.

PRODOTTO SORPRENDENTE ED INDISPENSABILE
Con l'angoscia di blackout improvvisi, con lo stress di non poter utilizzare appieno il macchinario ho acquistato una Easy longer es400-148 Wh l'installazione è semplice e intuitiva è dotato di quattro diversi agganci e con l'utente deve solo uniformare la tensione del macchinario al Easy longer. A parte non compreso nel confezione ho acquistato anche una connessione USB alimentazione elettrica Dove posso collegare il mio Easy longer ha un pannello solare da 100 Watt e ricaricarli in piena libertà ovunque mi trovo. Il prodotto è di ottima qualità molto molto efficace lunga durata mi permette di fare anche tre notti da 8 ore l'uno comunque è utilizzabile anche grazie alle connessioni USB e c, con con smartphone laptop tablet e altri supporti che necessitano un'alimentazione continua anche in posti non coperti dalla rete elettrica. Easy longer Es400 è indispensabile per chi è amante del campeggio o di coloro che meno fortunati non possono permettersi un collegamento elettrico costante è indispensabile nel pacchetto di sopravvivenza post eventi nazionali quindi valutatelo per un acquisto ottimo. Rapporto qualità prezzo spettacolare sicuramente ne comprerò un altro anche di più Potenza
