5 out of 5 eggs

This review is from: Vantec Power Gem Black 3500 mAh Rechargeable Portable Battery VAN-350BB-BK

Pros: Compact

Cons: Limited charge

Other Thoughts: We bought this battery for a vacation but when not on vacation my wife mostly uses this battery to charge her iPhone. The battery holds about two charges for an iPhone 4s. We found this battery doesn't charge iPads but just keeps the battery level stagnant when plugged in.

5 out of 5 eggsGood for multiple uses

This review is from: Vantec Power Gem Black 3500 mAh Rechargeable Portable Battery VAN-350BB-BK

Pros: Good for many full recharges of my phone.

Good for any super-low power 5V devices. Many of these batteries of this type will drop the output power pretty aggressively which makes them no good for very low power devices like a microcontroller. This one works very well for that use though. I've powered an Arduino based project for more than 24 hours (it could have run for another week).

Cons: Nothing significant. The case styling is a little goofy with those weird triangle facets. I suppose in a competitive market they try to do something random in order to stand out. But I'd buy more of these when the need arises.

Other Thoughts: It does exactly what you'd expect of it.

5 out of 5 eggsBest Charger Ever

This review is from: Vantec Power Gem Black 3500 mAh Rechargeable Portable Battery VAN-350BB-BK

Pros: This puts out 2 Amps and can charge a full size 3rd generation iPad or iPad Air. Of course can charge any cell phone with ease. It can charge your devices while being charged AT THE SAME TIME! I've never seen this with any USB charger. So a single USB wall charger can charge this device while the device also charges 2 cell phones attached to it. And this thing charges faster than most USB chargers, so you get more charge faster than usual. Important for short airport layovers. Last of all, the device stays on for a minute or two longer than most chargers, which means it doesn't auto-shutoff just because your cell phone became fully charged and stopped drawing juice. Tiny issue but most charges sense this, shut off in the middle of the night, and you wake up with your cell phone half charged in the morning because it was discharging for half the night. Won't happen with this charger.

Cons: None.

Other Thoughts: More than enough capacity to charge most cell phones at least once. Able to charge a full size iPad about 15%, which is amazing since iPads require 2 Amps and most USB chargers this size can't deliver this much juice.

5 out of 5 eggsThe Vantec Power Gem

This review is from: Vantec Power Gem Black 3500 mAh Rechargeable Portable Battery VAN-350BB-BK

Pros: very cheap, holds power for weeks, and comes in handy when travelling or during long nights when I'm playing in orchestrations. It charges quite fast even while having two charge both my galaxy and my ipod (4th gen).

Cons: none, only been 2 weeks tho.

Other Thoughts: its a little scary knowing that the charging usb ports are shown as only to be used for a certain brand of device (like port 1 is for idevices only and port 2 is strictly for androids), I'm wondering what would happen should I forget which port is for whatever device

5 out of 5 eggsI'm surprised, it's pretty great.

This review is from: Vantec Power Gem Black 3500 mAh Rechargeable Portable Battery VAN-350BB-BK

Pros: Cheap (Price)
Looks Fairly Nice
Can Charge Two Devices
Battery Charge Indicator

Cons: No "Included" Wall Adapter

Other Thoughts: Honestly, I got this on a flash sale for under $20 shipped. It does exactly what it says it will. I'm able to charge my iPhone 5 from being absolutely dead to full battery in under 2 hours. The build quality is better than I expected and really like the indicator LED's that can tell you how much charge the device has left.

It really works great for me. I usually forget to plug my phone in at night so I wake up with around 10% remaining. I can just throw it in my backpack and have enough charge to last me for the rest of the day by the time my first period class is over.
