Customer Reviews

  • Very Compact Li-Polymer Battery & Charger
  • I bought this from a well known online electronics company and received it a day ago. I am very impressed with it so far. It is about 4.5 X 2.5 X 0.375 inches thick and feels very dense and compact in your hand - a rock solid feel. It will easily fit in your pocket or even get lost in a woman's purse. I wasn't sure of the battery type when I ordered it, but learned afterwards that it is a Lithium Polymer battery. If I had known that was such a well designed unit, I would have purchased at least four of them instead of only one. There are four blue LEDs that flash according to battery charge level. There is a power button to press to charge or operate your 5 volt electronics device such as a tablet. There are two ports, one for your electronics device such as a tablet and one that you use to charge up the battery. A short white USB cable is included to charge the battery from your computer or USB AC wall charger. No AC charger is supplied.

    It is rated at 5 volts at 1 Ampere and 6000 mAh - a very useful rating. This morning I used it to charge up my high amperage Samsung Note 8.0 tablet/cell phone. The Note 8.0 started its charge at 46% and this SCUD battery charged it to full 100% battery charge within a hour, maybe less because I wasn't paying attention to the time. I should have timed it, but I forgot. I can honestly say I was surprised it charged up so quickly.

    Maybe I shouldn't say anything here, but the price I paid was one cent below fifteen including shipping on a flash sale, maybe never to be repeated. Now the price has almost doubled, which is still a good price. I really regret not buying more at that incredibly low introductory price. I just didn't believe it would be such a high quality product for such a low price. Today I ordered a silver version that is an open box item for eight dollars more. I'm taking a risk on an open box because it is probably a return for who knows what. I think it is worth the risk for one at that price. After I receive it, I may venture for another one if it works well. Be sure to shop around for the best price. I hope the price here becomes more competitive soon, because I prefer buying at Amazon.

Customer FAQ

Q1.  Do You Offer Repair On Broken Devices?
We unfortunately do not offer any repair services, if your device is defective please contact us for a warranty replacement *NOTE: Items within the warranty coverage are to be eligible for replacement service. Please review our warranty terms and conditions to verify that item is covered.
Q2.  Can I Use My Electronic Device While It Is Charging Through The Battery?
Yes you can, however we generally do not recommend using the electronic device while it is charging from our battery. It is best to let device fully charge before use.
Q3.  What Happens If I Plug My Phone Into The 2.1A Port? Can I Charge Two Phones At Once?
Although you can plug your phone into the 2.1A output for a quicker charge, we do not recommend doing so, as you are essentially outputting twice the charge into your phone's battery. As a result, the phone battery may generate more heat, which may affect the battery's lifetime, do so with caution.
Q4.  What Is The Difference Between The 1A And 2.1A Output Charge Ports?
1. The 1A is for cell/smart phones and other small devices. 2. The 2.1A is for larger devices, such as the Apple iPad and other tablets.
Q5.  Some Lights Are Blinking And Others Are Solid, Is My Battery Fully Charged?
1. When the LED lights are blinking, the battery is still charging, when certain lights are solid, a certain percentage of charge is complete (refer to B). If all LED lights are solid, then the battery is fully charged. 2. The battery's current level of charge is determined by the number of solid lights on the unit. Three total LEDs: 3/100 = 33.33% per light; Four total LEDs: 4/100 = 25% per light
Q6.  Why Does My Battery Not Charge My Electronic Device, Is It Fully Charged?
Certain models of our batteries have a delay function. To bypass the delay function, you need to depress the power button down from 2 to 5 seconds (depends on the model's configuration). The delay function is to protect the user from wasting power on their battery when the power button is accidentally depressed. *NOTE: Check out our troubleshooting section for further diagnostic if answer above did not fix issue.
Q7.  Can I Store My Batteries For An Extended Period Of Time And Only Use It For Emergencies?
We do not recommend storing our batteries (or any batteries) over a long period of time without use. As the battery cells will deteriorate when they’re not in use. Furthermore, the batteries you store will constantly lose energy over time. If the stored batteries are completely discharged, certain negative detriments may occur, which include the failure in starting up. To maximize the lifespan of your external battery, we would advise you to fully discharge and recharge the battery at least once (recommended twice) a month and follow the maintenance recommendations.
Q8.  Can Your Batteries Be Carried On Plane?
According to TSA battery regulations, our products fall well within the restriction posted for Li ion battery carry-on, and are limited to two large size batteries. Further detail can be found on TSA website. *NOTE: Even if an item is generally permitted, it may be subject to additional screening or not allowed through the checkpoint if it triggers an alarm during the screening process, appears to have been tampered with, or poses other security concerns. The final decision rests with TSA on whether to allow any items on the plane. We do not guarantee or 100% confirm our batteries can be carried or used on a plane, other than confirming that our battery follows TSA guidelines. We accept no responsibility of denying of battery carry-on and other issues that may occur while at the airport.
Q9.  Can Your Battery Be Used Overseas In 220-240V Countries Like Vietnam, India, Africa, Europe, Etc…?
Yes, our battery can be used overseas with no issues. Our batteries are charged from two sources: a USB port and an AC wall charger. USB will not be affected, provided the correct Wall adapter is used. AC batteries are supplied with universal AC wall chargers 100-240V. (You do not need a voltage converter, just a travel adapter to convert US pin on AC adapter.)
Q10.  Where Can I Get Your Device Locally, Is It Available At Any Retail Store?
Unfortunately, our products are only currently available online through us directly or through our reputable authorized re-sellers.
Q11.  Do You Sell/Ship Internationally?
Our sales channel is only limited to USA, we do not have international sales channels at the moment. If you'd like to purchase our product and reside outside the USA, you can seek the help of an international forwarder. There are several located in New York; look them up on any search engine to determine the details. Order an item from our site and have it shipped to your forwarder of choice and they will forward it internationally to you. *NOTE: There are restrictions to our customer support/warranty coverage for international customers, please review our warranty section for further details.
Q12.  Does The Battery Stay On After The Device Has Fully Charged?
The battery has a built-in auto shut-off feature and will shut off if the device in charging has completely charged, or if battery is inactive for 10 seconds. This is to maximize battery life and provide you the maximum charge for your device when you need it the most.
Q13.  Can My Device Charge From The Battery While The Battery Itself Is Charging?
Our batteries do not support "pass-through" or "daisy chain" charging at this time. We do not recommend charging your device from our battery while the battery itself is being charged from a power source, as this will severely stress the battery cells due to constant charging and discharging and will have a negative impact on the battery and the overall lifespan of the battery. At this time, we would advise all users to charge the batteries first, before using it to charge other devices. *NOTE: This feature is being deactivated on all of the new batteries.
Q14.  Do These External Batteries Support The Latest Apple Devices?
Yes, all of our external batteries are actually compatible with the latest Apple devices such as iPhone 5 and iPad 4, as well as the prior iterations and iPod Touch devices (Certain classic models excluded). Our battery will charge your Apple device by using the original white Apple cable that came with the Apple devices. *NOTE: The Lightning cable and 30 pin Apple charge cable is a proprietary standard that only Apple manufacturers have the license to. Due to the licensing, we are not able to produce or distribute these cables at the moment.
Q15.  Is My Device Compatible With Your Device Even Though It's Not Listed In The Compatibility List?
The battery should be compatible with most 5V or USB chargeable smart phones, tablets and portable devices (GPS, portable cameras, etc.), since our battery is only able to provide a 5V output. You can double confirm your device compatibility by having a look at the AC wall charger for your phone or tablet. On it there should be a sticker with an output rating, if it has a 5V OUTPUT then your device is compatible with our battery. Some device will need the "galaxy tab converter cable" to properly charge. Examples of compatible devices: galaxy tab, nexus 7, PS vita, etc. Examples of incompatible devices: ASUS tablet transformer series requires 15V, and Laptops of all make requires 12V- 19V, etc
