RAVPower FBA_RP-PB055(B) AC Portable Charger, 27000mAh 100W(Max.) Built in 110V AC Outlet Universal Power Bank Travel Charger (Type-C Port, Dual USB iSmart Ports, 19V/1.6A DC Input) for MacBook, Laptops, Smartphone, Black

If you are a power user who needs to actually WORK on your laptop all day away from AC Power, this is the product for you. I am using a 13" Macbook Pro (2010, Unibody) and with this battery I can run all day at 100% screen brightness, w/ WiFi and multiple applications running all day long. Towards the end of the day I will usually deplete this battery, but with my laptop's onboard battery as a reserve I can now work all day long with no problems.

I bought this used and so far so good! It came fully charged which was super convenient because I had a busy day ahead of meKeep in mind this is a larger portable battery, that was not an issue for me as I was looking for something with a 3prong capability.And for this price! You can find much else out there with 3prong capability with this capacity

Works great but AC output is modified square wave which will not work with some AC equipment within specified power rating..

A pretty big and heavy battery, but at 27000 mAh you kind of understand that weight and size are going to be the trade off. Has an AC outlet, 2 'regular' USB ports, and 1 USB type-C port... for ***output*** only.Comes with a charger (see photos). I really wished that RAVPower made this thing be able to charge from it's USB Type-C port so that way I can bring one less cable (since my phone charges with a USB Type-C cable). But this was a major bummer when I tried this out.None the less, so far so good, works just like a trusty USB battery and can charge laptops. Charges my Macbook Pro 13 inch 2014 fine with a 45 Watt charger so far.Anyways just wanted to let out the comment about the Type-C port. Enjoy the photos!Let me know if you guys have any other questions, comments, or requests.

Product worked good especially the pass through feature save time it just means that it allows you to power your device and charge itself at the same time. Would recommend this to others.

Yeah. It seems nice so far. I hope the battery lasts as long as they advertise. The exterior has that really nice smooth matte plastic feel. Also, the web listing did not mention the extras it came with. It came with a rigid fabric covered case, and a mesh pocket and two micro usb charging cables (Plus its own charging cable) So yeah it seems nice. My only concern is accidentally pressing the power button if it is just in my bag. But the manual says it automatically turns off after a minute w/o draw... so I guess that is good.

how can you go wrong with this beast???? it's been all over the world with me.. life is easy with this unit. no idea why anyone would complain about it.. if you are an EE worrying about nano electrons.. well then... but for day to day use.. it's awesome...

Was looking for something to run my Cpap. Seems to work with heater on but I use it without to make sure the battery lasts longer. Wanted a goal zero Sherpa 100 but caught this on sale for $119. Not sure if it can be solar charged but I'm not off grid long enough to need that. customer service told me the DC input connector is 2.5 in diameter so I'm debating trying a USB to 2.5 cable with a 19v usb solar panel at some point . I like the case it came with and the small form factor compared to some other battery/inverter combo gadgets.

C'est du Ravpower, ca fonctionne parfait. Je le traine dans le sac à dos, j'y recharge en permanence mes batteries d'appareil photo (normalement ne se charge que sur prises 220, et là miracle il y a une sortie pour ces prises là !!!! ).Appareils, ordi, Iphone, tout y passe, meme les potes viennent squatter mon sac pendant les randonnées. Du coup au vu du poids (1kg tout de meme - faut ce qu'il faut on a rien sans rien) je le refile à porter au destinataire du chargement (faut pas pousser quand meme)Ca chauffe un peu donc ne le laissez pas enfermé dans la saccoche quand vous chargez.Adepte des randonnées / road trip extérieur et des visites marathon, ce truc m'a donné une autonomie remarquable. Je ne m'en lasse plus.

Bon rapport Q/P, longue autonomie (>1h à pleine puissance) et pas de surchauffe.Charge assez rapidement.La puissance maxi en 230V est vite atteinte, bien faire attention à la puissance des appareilles connectés. Une sécurité empêche la surchauffe ou l'explosion si cette puissance maximum est dépassé mais la batterie s’arrête toute seule.

La cosa che più mi è piaciuta è la presa elettrica adatta a chi, come me, ha un vecchio portatile. La durata della batteria è consona a quanto pubblicizzato.

Le produit m'avait été recommandé par un ami, et correspondait donc exactement à mon besoin: c'est pour cela que je l'ai acheté…Les deux gros plus de ce produits: sa grande capacité, mais surtout sa sortie 220 volts directe qui permet d'y brancher n'importe quel appareil (dans la limite de la puissance de sortie de la batterie évidemment…).Mon usage: recharger une batterie de moto dans un box qui n'a pas de prise de courant.

cette batterie est trés pratique pour mon surface book , ou tous ce qui fait -19v , petite précision il s'agit d'une batterie de "27a" A 5 vots , soit en tout un max de 100 watt et donc 1 heure pour la vidé ! perso mon "surface book" en mode d'énergie normal consomme 20w , et avec la perte inévitable des batterie "chaleur" j'en ai pour 4 heures d'autonomie , et , en mode économie d'énergie 10w , environs 8 heures .
