UNU Enerpak Vault Dual USB 2.1A Universal Battery Pack for Smartphones and Tablets

Massive Capacity, Dual Port and Portable Design - The Most Powerful Enerpak

UNU Enerpak Vault Universal Battery Pack

Secure the ultimate power with the Enerpak Vault Universal Battery Pack. Designed and constructed to be the apex of battery power, the Vault boasts a massive 11,000mAh capacity. This huge capacity is capable of powering tablets, phones, and almost any other portable device, making it ideal for extended trips and high-demand users. Also, engineered to have two USB-ports, each with its own unique power output, the Enerpak Vault allows for tablets and phones or other small devices to be charged simultaneously to maximize productivity.




Immense Battery Life

Equipped with UNU's largest battery yet, the Enerpak Vault packs a whopping 11,000mAh. The power potential carried by a fully-charged vault can completely power any tablet (including the iPad) and re-charge any smartphone up to six times!


Technologically Advanced

Combining astounding power with industry-leading technology, the Enerpak Vault boasts a plethora of benefits. Designed with two USB ports for charging multiple devices, an LED battery capacity status indicator, and state-of-the-art battery circuitry to ensure optimal efficiency, the Vault is the only battery for providing massive amounts of high-powered, reliable energy.


Dual Port Charging with 2.1A Output

Made to increase productivity, the Enerpak Vault comes equipped with two different USB ports which can power devices simultaneously. The first, capable of charging at 2.1A is perfect for charging larger devices - including tablets - quickly and reliably. The second USB port is made for charging almost any phone or small electronic device to ensure on-the-go readiness.


Better Batteries

Using a lithium polymer compound in the Enerpak Vault allows for a longer-lasting, highly-efficient, safer, and more eco-friendly battery. Also, the Enerpak Vault, using newly created battery technology and circuitry grants better throughput and power conversion than traditional USB batteries.


The Power of "UNU-versal"

Using a 1A USB port to charge almost any USB device, the Enerpak Tube effectively charges most electronics at significantly superior speeds compared to traditional USB batteries. Therefore, no matter what the device, an alternative power source is always within reach.

3 out of 5 eggsEternity

Pros: Like the ability to charge two devices at a time from this battery. The battery charges devices in a reasonably quick time.

Cons: Takes a bleeping eternity for the darn thing to charge all the way up! It's roughly around 12 hours to fully charge using my highest capacity USB charger as input. That USB charger normally charges up my Samsung phone in 2 hours. Drives me insane waiting for this thing to get done!

Other Thoughts: I will never buy another battery like this that charges via USB. It's a complete agony. I have another battery that charges from higher voltage input - I will get another one like that when the time comes even though it cost twice as much as this product.

4 out of 5 eggsPortable Power

Pros: Great battery life, can fully charge my phone and ipod for a good week or two.

Cons: The shipping of my item was outrageous. I placed the order with 1-day shipping so it would arrive the next day (Thursday to Friday) for a vacation trip. It didn't arrive until the day we got back from vacation! (Next Friday) That's over a whole 4 business day's late.

Other Thoughts: Just thought people actually hoping to receive this when ordered weren't fooled.

5 out of 5 eggsWow.

Pros: Fast charging
Never runs out
build quality (dropped it a couple times and still works)

Cons: Not really a whole lot actually, people make fun of me for spending this much on a battery bank and I just laugh at them because the don't have one.

Other Thoughts: These things are AMAZING!!! I have the "bigger brother" to this thing and this charges JUST as fast! These two little items are the bomb diggity.

5 out of 5 eggsPower for days

Pros: This thing has enough power to last 2 days of ridiculously heavy phone use. Seriously, you won't run out of power if you try- unless you forget to charge it up. Can even charge my tablet. Plastic exterior seems sturdy enough, but may crack if drooped from a good height. Ports are not loose, overall very good quality construction. For under 50 bucks you won't be disappointed.

Cons: My only real issue is the battery indicator lights. They are nearly invisible in bright light, although not a big issue. The bigger problem with them is that power remaining isn't linear at all. With 4 indicator lights I assumed 2 lights lit means 25-50% power left, but once it dropped to a single light it was dead within 20 minutes. Pro tip: 2 lights means charge it tonight.

5 out of 5 eggsPerfect!

Pros: Huge capacity (charges my galaxy s4 at minimum 3 or 4 times without being empty) I've never emptied it because it's so huge, so I don't know the real exact number of charges, but it's really great!

Cons: Really huge. It feels like carrying an external 2,5 inch hard drive to power your phone. It's doeable, but still big.

Other Thoughts: A must buy if you need an incredibly high performance external power source!

5 out of 5 eggsA reliable charging system, finally!

Pros: With all of the power supplies that flat-out don't work, it's nice to find one that holds a charge and powers everything. I've had it for about 6 months now. I use it with my eSATA portable drives to back up video shoots. It allows me the speed of eSATA without having to find an outlet. I can back up for hours on this thing. I can also charge my phone, iPod and iPad as well. The 1 amp port is fine for the ipod, but that wonderful 2 amp is what you buy this for. It gives wicked fast charges, as fast as a wall charger. And my hard drives won't spin up with 1 amp. I've bought those gigantic Energizer chargers that are supposed to run a laptop (but don't) and they just don't hold a charge. I can rely on this thing. Love it.

Cons: none, really

5 out of 5 eggsWorks like a Charm

Pros: This UNU has a 1 amp and 2 amp usb port - you can charge dual electronics at the same time. It holds power for quite some time on it's own. It has come in very handy during loss of power due to storms.

Cons: a little bigger than I would like
