As the 2015 holiday season approaches, we decided to update our amazon best portable charger selection lists. After all the power bank market is very dynamic with new or updated models showing up almost daily. Our lists also grew bigger and now contain 15 best sellers for both compact and high capacity portable charger lists.

In addition to the best selling amazon portable charger list update with new best sellers, we also decided to create a list that our editors found worth sharing with our readers. They all are some great finds that in our opinion are some of the best portable chargers listed on amazon's website.

Lastly, because of growing interest we included two more listing from new technology categories. They are: solar power chargers and accessories and Qualcom Quick Charging power banks and accessories

What is it and why do I need a portable charger / power bank

Our phones become evermore powerful and essential in our lives. They are now not only our communication devices but they become our mini offices and personal assistants that we take with us everywhere. Their screens grew bigger and number of applications available for them is growing every day. As a result we relay on them to be charged and ready for use at all times. Manufacturer's "stand-by time" per battery charge lost its meaning because we hardly ever have our phones in the stand-by mode. It is not uncommon to charge our phone a few times a day and as long as we have a power outlet handy we learned to accept this as a part of our daily routine. But many times we find ourselves in a situation when we don't have access to a power outlet or we can't afford to be "tied-down" with our cell phone charger cable. But there is a solution that can solve those problems and it is called a battery portable charger or a power bank. Power bank is a device designed and build with one goal: keep our phones charged and ready even if we don't have access to a power outlet. Portable chargers not only provide an emergency energy source for our phones, tablets or any other device that can be plugged into a USB power source but can also relatively quickly charge our phone's battery. In simple terms a power bank is a portable charger that doesn't need an outlet to charge our phone. In most cases a power bank is small enough to fit in our pocket or a purse and we can take them with us anywhere we go.

What to look for when searching for the best portable charger for your phone or your tablet

We based our Top 10 power bank selection on multiple factors and device technical characteristics in addition to the Amazon Bestseller status. In our decision making process we looked at a product's user reviews and ratings, Amazon bestseller status and also weighted in our staff's expert opinion. Many of our choices match consumers' preferences that made a particular power bank an Amazon Bestseller and they all deserve the title of the best portable charger, but we also included a few portable chargers that are not best sellers on Amazon and yet we found their quality and value compelling enough to include them in our list. In our search for the best portable charger the evaluation process was primarily based on the following characteristics of selected power bank:

• Total Capacity - expressed in milliamp hours or mAh
• Amperage Rating - expressed in amps or A
• Portability
• Durability
• Design And Extra Features

Portable charger's total battery capacity

Battery capacity indicates how much electricity it can store. When you consider buying an external battery charger you need to consider your needs. When you plan to use it only for emergency charges for your phone the range of 3000mAh - 5000mAh should be enough to provide you with 1-2 full charges for your phone, depending on your phone battery capacity. However if you plan to use it for more than one phone or maybe a tablet you might consider a portable charger/power bank with capacity of 10000mAh and over. Just keep in mind that the higher the capacity the bigger the overall battery charger size. All of our picks feature at least 3000mAh for the compact models and 10000mAh and over for more bulkier multi-phone or tablet models. The highest capacity among our portable chargers belongs to Anker� Astro E7 Ultra-High Capacity Compact Portable Battery Charger, its whopping 25600mAh (11/9/2015: Now upgraded to 26800mAh) should be enough for multiple charges for your phone and tablet.

Portable charger's USB charging port amperage rating

Portable charger amperage rating tells us how fast the electricity is going through a USB port and into our phone's internal battery. Which by the way is true as much for external battery chargers as it is for wall chargers. When picking the best portable charger make sure that the USB port amperage rating is 1A or greater. If you ever tried to charge your tablet or even a phone from your laptop's USB port, chances are that you could see on your phone or tablet that the external power source was connected but the battery was either charging very slowly or not at all. The reason for this behavior is that standard laptop's USB ports are only 0.5A and charging any device from such a port takes a long time in the best case scenario. All power banks in our review are at least 1A rated and many feature ports rated at 2A or higher.

Portable charger's/power bank's portability

When choosing a power bank for our phone we should ask ourselves a few questions concerned with intended use. For example: How are you going to carry your power bank? Are going to carry it in your purse or a pocket and is your phone the only device that you plan to charge with your portable charger? If so you should pick a smallest compact model. You should know that there are some power banks that are not much bigger then a lipstick. All portable chargers included in our review, even the smallest models, should provide you with at least one full charge for your phone.

Portable charger's battery durability

All our selected power banks feature modern Lithium-Ion technology (they are not susceptible to Memory Effect that was common with older battery types) and they can last at least 500 full charge cycles (one charge cycle = 0% to 100% OR 2x[50% to 100%]), so even with a daily use they should last for not less than 2 years.

Portable charger's extras

In some cases you might consider some extra features that will meet your particular needs. Among our selected portable chargers there are some models that feature:

• Waterproof/Shockproof design (SadoTech 10400mAh Portable Charger)
• Flash Light (SadoTech 10400mAh Portable Charger; Acuvar Power Bank Portable Backup Battery Charger; KMAX-806 External Travel Battery Pack)
• Multiple USB Ports (All High Capacity Models except KMAX-806 External Travel Battery Pack)
• Solar Panel Recharge (LevinTM Solstar Solar Panel Charger) Late addition 01/09/2015

We also collected a few wall/car charger and other accessory item recommendations for you. After all our power bank is useless unless it is charged.
