Hurricane Sandy hit the New York area in the fall of 2012, effecting over 200,000 of us who got caught up in the fury of the deadliest and most destructive hurricane of the 2012 Atlantic hurricane season. With power out for much of us in Lower Manhattan for days, it became time to take a a more serious look at emergency preparedness. Luckily I was well-prepared for the five-day power outages we went through, but one can never be prepared enough.

Etón BoostBloc 4000 is a small, compact device that is designed to serve as a portable backup battery pack and charger for smartphones and other USB-powered devices. It's deceptively compact, more than one might guess from the images here. At a total of 4000mAh, it's listed as offering "two full charges for most phones," but more on this later.

I'll list the subjective pros and cons found so far with this portable backup battery pack/charger for those looking for just the key points, then follow with some expanded details.

◆ High Points:

+ Compact; fits easily in your hand, 1.0"H x 2.2"W x 2.2"D, weighs ~3¾ ounces
+ Clean, minimalist design; fits into any work or professional environment
+ Micro-USB DC input; allow for connection to most USB chargers
+ LED charge indicators; four levels, activated by a shake
+ Micro-USB cable included; about 2-feet long

◆ Low Points:

- May or may not live up to "two full charges" claim. See below.

◆ In Use:

The Etón BoostBloc 4000 comes packaged in a clear presentation box that's easy to open, and (luckily for us) not one of those clamshell packages.

I love my little BoostBloc, it's small enough to carry around in my bag everywhere I go. I can usually get a few charges out of it. Though I usually don't charge my phone all the way back up, just enough of a boost to get me through the rest of a long day. The bloc itself charges FAST, I plug it in and 30 minutes later all the little charge level lights are on indicating a full charge.

I will note that I do not think they are worth paying the full price for. Shop around, I got mine for MUCH cheaper than amazon lists them at.

I own a couple of different battery packs as I have a smartphone that loves to each it's charge up when I'm hiking/biking and away from an outlet. I own a couple other Eton products and decided I would try this block from them. I'm glad I did. I can throw this in my pack when out and about and keep my phone charged wherever I go. It's been very reliable and holds it's charge well when not using it for long periods of time. I've also charged my phone up to three times from 25% to 100% on a single charge. It's also one of the few external chargers like this that will charge my Kindle Fire HD 8.9. Very helpful if I'm out camping and I want to watch a movie that I've downloaded to the Kindle. I've had this for almost a year now and it stays in my backpack ready when I need it. I lost my first one somewhere and couldn't live without it so I bought a second one almost immediately. Worth the investment for me and has paid for itself several times by providing power in situations where I needed it.

Purchased this for a trip to Disney world to keep the phones/ go pro camera charged for a full 7am to 11pm day at the park. Worked great. Had enough charge to power up an IPhone 5s and a SGS2 with power left over. The go pro did not use a much battery as I thought it would. I have used it on other trips and same results. The blue lights indicating the amount of charge are great just give the block a shake. NOTE. Be sure to pack your charging cables specific to your phone or device; this only has a cord for you to charge the block.

Fabulous charger! It actually works as advertised. This is great for emergency preparedness - you never know when the lights will go out! I also like it for camping and other activities where power isn't readily available. It's very compact and easy to use. And who can resist red?!?

This can be very convenient! i have had this for a few years now, and it still works as well as the day i got it. uses the same charger as most android phones, holds a charge for a while, and can recharge a phone 2-3 times. I used it all the time in the army, it was great for those week long ranges and longer training events. i would definitely recommend if you need to charge the phone often, or for an emergency if you are going for a longer trip.

This does not work. I got stuck on a plane for 4.5 hours on the runway and it didn't work for my iphone or I pad. My husband tried it with his kindle fire and Samsung note-nothing--as is DOES NOT WORK at all. I just looked up the return policy and since we didn't try to use this in a real life circumstance within 30 days, we can't return it?? So we're out $80. Very disappointed. I bought off from a recommendation off Samantha Brown of Travel Channel fame's website-I hope hers worked. Great idea-wish I could exchange it.
