Product Description

Although this 60Wh battery will work with the MacBook Pro 15/17 inch, it is not recommended as the MacBook Pro 15/17 inch draws up to 85W of power. Battery physics dictate that a 60Wh battery is most efficient at providing up to 60W (1C) of power. A 60Wh battery can still provide 85W of power but at lesser efficiency, approximately only 70% of a 60Wh battery capacity will be available to the MacBook Pro 15/17 inch. The remaining battery capacity will still be available to lower power devices like the iPhone. This power limitation affects all batteries with capacities lesser than 85W and is not specific to the HyperJuice. This does not affect the MacBook and MacBook Pro 13 inch which draws up to 45W, 55W and 60W power respectively, which are equal or lesser than 60W. MacBook Pro 15/17 inch users are recommended to use at least a 100Wh battery which can efficiently provide up to 100W (1C) of power. Likewise a 150Wh/222Wh battery can efficiently provide up to 150W/222W of power respectively.

HyperJuice External Battery 60Wh for iPad/iPad 2 and MacBooks - Silver - MBP60 Review

I''ve had the 60 watt / MBP-060 for about a year. It is very well made with metal enclosure and it charges up quickly. I normally carry two Ipads and a MacBook Pro 13 inch with me working on all three at the same time. I power the Ipads from the USB ports on the Mac and I plug the HyperMac Battery into the Mac's power port.

This being said the Mac, and both Ipads are drawing power from the HyperMac Battery. Doing this, the whole setup runs for about an hour or less.

If I use the HyperMac with just the MacBook Pro 13 inch I get probably about 2 hours of use out of this external battery. This means that if you've used the Mac most of the day and it's now running dead, you can plug in the battery to the Mac and you'll get at least another hour of use to do emails, etc.

I didn't prepare to write this review which is the reason I'm being fairly general, but I noticed there were no other reviews and I'm thinking about getting another one. If it sold for about $50 less, I'd have already done so.

When I looked at the unit online there was some confusion from looking at the website and other information about how you hook it up to the Mac. I thought there was a two-piece cable and some other item I might have to purchase. (One can get lost with words like magsafe, etc.) Actually what you get is the battery, which is very rugged, a charger which plugs into the battery, a charging cable which plugs into the wall and connects to the charger itself, and a separate cable which runs from the battery to the Mac. I leave the charger and charger cable at home and just bring the battery and the supplied power cable which goes from the battery to the Mac when I go somewhere. I have also used the battery around home and noticed the battery will charge completely from being dead to a full charge in about two hours.

I also use this battery to power an Ipad from the USB port on it and I haven't depleted it from seemingly a full day's use. I try to keep the Ipad batteries at full charge a good bit as I am traveling to various locations throughout the area due to my work and use both of them througout the day.

Other than this particular battery, I have found the NewTrent IMP1000 (from Amazon) is a great unit for powering an Ipad, charges quickly and lasts a good while. With the New Trent it has a separate battery charger as well, but just has a USB and can't (obviously) charge a MacBook. To further get off topic,I also use several APC UPB10 batteries which have a USB port, will operate an Ipad for about 2 hours of intense use and charge off of a mini-usb cable (meaning it can be charged off the computer or another USB port). The New Trent IMP1000 is a good unit, but stays home a good bit due to the need for an external specific charger but the APC UPB10's tend to go with me everywhere as they're small and I don't need to carry another charger. A mini USB cable and an Iphone charger will do the trick and the APC's will charge a phone or an Ipad...and smaller than a deck of cards.

Getting back to the HyperMac, Amazon seems to have the lowest price on these batteries. They're well made, well designed, and are keepers. (Some others, which I haven't mentioned...are not). The problem with the HyperMac, they're expensive.

One of the things I'm thining about doing is getting a second one of the same size, another 60 watt. In doing so I can use one while the other is on charge. In so doing one would be almost fully charged by the time the first one is depleted. This means I could continually swap out batteries to keep a computer going. By buying two of the same type I can keep one charger in a travel bag, the second one at home, etc. I have several types of external batteries for Ipads, Iphones, etc. and other than the APC they each have a unique charger...which is a pain.

Whatever you end up doing, you also may want to adjust things such as hard drive usage, the light intensity on the display, etc. I tend to keep everything going so you may actually get longer run times than Ive mentioned above.

Is this a good battery...yes! Is it well designed...yes! Is it reliable, charges quickly, holds a charge and does what they say it will do...yes! (I just hate they cost as much as they do...if they cost about $100 or so, I'd own several instead of just the one I have.)
