The contest

1- Why you ought to believe me:

I spent 21 hours studying and 55 hours testing USB power banks and portable chargers for my buying guide. I’ve been writing about science for almost ten years, covering everything from particle physics to satellite remote sensing. I have written on surge protectors, USB-C cables and adapters, portable chargers and power supplies, and other topics.

2- Whom is this for:

Most people could charge their phones and other gadgets while they were on the road using a USB power bank, often known as an external battery pack, backup battery, or portable chargers. Which one does your habits match the best, is the question.

Some people might just want a modest battery to recharge their phone at the end of the day, whereas frequent travellers could need to power several devices for several days. Owning a USB power bank enables you to take advantage of a conveniently portable chargers and portable (albeit constrained) power supply rather than always needing to locate a wall outlet wherever you go.

Even if you have access to numerous charging stations throughout the day—perhaps you spend the most of your time at home, at work, or in the car—you could definitely still use a portable power bank and portable chargers. When your phone dies unexpectedly and there are no outlets around, it’s great to always have something small and portable with you.

However, slightly larger power banks that can provide two or more full charges for the majority of smartphones can still easily fit in laptop bags, purses, or large pockets if you’re looking for something for weekend getaways or your daily commute. These durable yet lightweight power banks and portable chargers let you to charge a variety of gadgets, including wireless headphones, computer mice, keyboards, vaporizers, digital cameras, and more.

A USB power bank could be useful to most individuals. Which one does your habits match the best, is the question?

A power bank or portable chargers provides additional peace of mind when you’re travelling in an unknown location and relying on your phone to direct you and possibly contact for assistance. It wouldn’t hurt to strategically place a few of these throughout the house:

Keep one on the couch for when you’re wrapped up cosily beneath a blanket and really, really don’t want to get up to plug in your phone, or keep one in your foyer for when you’re rushing out the door.

3- How we chose:

Unfortunately, battery technology has not kept up with the processing power of current gadgets, thus USB power banks and portable chargers have grown in popularity as a way to extend the battery life of smartphones and tablets. We looked at big retailers like Amazon, Home Depot, and Target as well as respected media outlets like CNET, PCMag, PCWorld, and TechRadar to locate the most well-known manufacturers of widely available USB power banks and portable chargers because there are so many different brands and models to select from.

From there, we developed a list of potential candidates based on the following characteristics:

Strong Recharging and Charging With Portable Chargers:

We selected products rated for at least 15 watts for USB-C output or input. Although devices that support the even faster USB-C standard—USB Power Delivery, or USB PD—need at least 18 watts, that is the minimum amount of power required for full USB-C charging and recharging speeds.

Similarly, we sought for devices with USB-A output or Micro-USB input rated for 8 watts or greater. Anything less would be agonisingly slow.

Power banks and Portable Chargers ought to be light and compact, weighing no more than half a pound, and simple to carry all day long in a wallet, pocket, or bag. We chose to evaluate power banks or portable chargers that weighed 8 ounces or less because we don’t believe that most people want to carry around a device that is significantly heavier than a smartphone (for comparison, an iPhone 13 weighs 6.1 ounces and a Pixel 5a weighs 6.5 ounces).

From 1,000 to 10,000 mAh in Capacity: You can generally estimate how much power a power bank or portable chargers can hold by looking at its capacity rating. For comparison, a 16-inch MacBook Pro battery has a capacity of 100 watt-hours (or about 28,000 mAh), whereas an iPhone 13 battery has a little bit more than 12 watt-hours (or about 3,300 mAh).

For this guide, we mainly focused on power banks and portable chargers with lower capacities—those that store enough capacity to give your phone a boost of power or to fully charge it several times Compared to the chargers we suggest here, our favourite power banks and portable chargers for laptops with USB-C or AC charging offer substantially higher capacity ratings.without making you uncomfortable.

Power banks and Portable Chargers with a capacity rating of more than 10,000 mAh tend to be bigger, heavier, and more expensive.

At least a one-year guarantee is recommended, while extended warranties are, of course, always desirable. A year is plenty of time to use your power bank or portable chargers and ensure that it is functioning properly.

Reputation of the brand:

When it comes to prompt customer service, extensive availability, and the ability to maintain models in stock, we gave preference to businesses with which we had previously had mainly positive experiences. We excluded firms without a clear online presence as well as models that were currently in the middle of a crowdfunding campaign.

Price: To distinguish between models that were otherwise comparable, we utilised a capacity-to-dollar ratio (mAh/$).

Built-in Plugs or Cables: We preferred power banks and portable chargers with a built-in plug or cable of some kind. When implemented properly, this kind of feature is essential because separate charging cords take up more room in a backpack (even if they are neatly coiled up).

Following This Procedure, We had 23 Power Banks and Portable Chargers to Test:

In the market have very big number of variety of power banks and portable chargers, but due to their configuration their weights and their models few’s are in the below.

4- Zendure SuperMini 20W Portable Chargers is Our Choice:

When it comes to charging a smartphone or other small electrical gadget while on the road, the Zendure SuperMini 20W portable chargers provides the whole solution. Its capacity rating is the highest of any we’ve tested, despite being small and lightweight (about the size of a deck of cards and as heavy as an iPhone 13). These power banks or portable chargers to acquire if you want one that you can simply slip into a pocket or handbag as you head out the door but that yet has enough power to charge the majority of smartphones up to three times.

The Zendure has a port on either end: a conventional USB-A port that can only be used for output on one side and a USB-C PD port that can be used for input and output on the other. In our tests, we found that the USB-C port had a maximum output of 18.6 watts, a maximum input of 19.3 watts, and a maximum output of 16.6 watts.

Although those figures fall a little shy of the SuperMini’s 20 W output rating, it is still powerful enough to charge the majority of devices at their fastest possible rates from either port or to charge two devices at slightly slower rates. With a 10,000 mAh capacity rating, your phone may be fully charged up to three times. You can also instantly make friends by topping off strangers’ phones; this is known as “bumming a cigarette” in the digital era.

The Zendure’s exterior is made of a strong, polished plastic shell that is moderately resistant to scratches and dings. It fits in the palm of your hand and is available in a number of colours, including red, green, black, silver, blue, and pink. It is also just 3.1 by 2.2 by 1 inches in size. A hockey puck’s worth of weight, or 6.4 ounces, makes it lighter than any other 10,000 mAh power bank we’ve tested.

Zendure’s two-year guarantee, which is the longest of any model we evaluated, covers the SuperMini device, giving you plenty of time to test it out and make sure you don’t receive a defective item. In the more than five years that we have been reviewing Zendure’s products, we have also had positive experiences with their customer service.

5- Deficiencies but not deal breakers:

The SuperMini’s absence of integrated cables is a significant flaw. Instead of providing and hauling our own cords, which take up additional room, tangle, and are simple to lose, we prefer having built-in cables for charging our gadgets. The SuperMini requires a separate cable to recharge itself (one is provided in the box), unlike our other recommendations, which can recharge using built-in cables or sockets.

However, we believe that the fact that it fits so much power into such a compact space overcomes the little inconvenience of needing to bring one or more additional charging cables. Additionally, it means that the SuperMini can now charge a wider range of gadgets, especially older models without the newest connectors.

Although it seems like a miniature hardshell luggage, the raised ridges on the SuperMini’s major surfaces are an aesthetic flaw that we don’t particularly enjoy. Additionally, these protrusions make it simpler to feel for the power bank among the other items in a purse or tote. In comparison to other versions we’ve examined that have entirely smooth exteriors, they also add a little more grippiness.

6- Other Excellent Power Banks:

The next-best option in terms of capacity and portability if the Zendure SuperMini 20W is not available is: Depending on the pricing and the style and colour you like, choose between the Anker PowerCore 10000 PD Redux and the Anker PowerCore Slim 10000 PD.

Both variants are roughly as pocketable and have the same capacity as the SuperMini (10,000 mAh), although being a tiny bit larger. The SuperMini weighs 6.4 ounces, the Redux 6.8 ounces, and the Slim 7.4 ounces, respectively. Both variants, like the SuperMini, contain a USB-C PD connector that can swiftly recharge a smartphone or other portable device as well as a USB-A output port.

If you don’t mind giving up some power and would rather have an upholstered exterior than the hard, plastic finishes of our picks:

Consider purchasing the ZMI PowerPack 10K USB-C Power Bank (QB910). The ZMI boasts ergonomically contoured corners and a 10,000 mAh capacity rating, just like the three chargers listed previously. Its 7.4 ounce weight is comparable to that of an iPhone 13 Pro. Although we measured an outstanding 15.6 W from its USB-A connector, it fell short in our tests for maximum output, managing just 16 W from its USB-C PD port.

We measured 16.9 W of input through USB-C PD and a pitiful 4 W over Micro-USB. The ZMI includes a fabric pouch and a USB-C charging cable (the SuperMini, It also includes a useful two-in-one cable (a Micro-USB cable with a USB-C adaptor attached at the end by a short tether), as do Redux and Slim. This fabric-covered device looks more fashionable and upscale than the majority of the other fabric-covered devices we’ve examined; it’s a soft, densely woven, marled-gray twill. It is stain-resistant but not particularly resilient.

Get the Anker PowerCore Fusion 10000 if you want a power bank that can also be used as a wall charger. Its design makes it simple to slip into your pocket, and its easy fold-up plug and battery-status indicators let you know when a recharge is necessary.

This one, like our top option, has a capacity rating of 10,000 mAh, which is sufficient for around three complete phone charges. It also comes in three colours (black, white, and red) and has a matte texture that is pleasantly gripping and comfortable to handle. Because it weighs a massive 9.6 ounces, which is a lot more than our top option, we decided against making it our official pick. But this is your best option if you need more capacity and don’t mind the added size.

7- What to Anticipate:

For spring 2023, we’re organising another round of testing in which our best choice will go up against the following models:

Belkin BoostCharge Plus 10K

Clutch V3 Lightning (iPhone)

Clutch V3 USB-C (Android)

Mophie Powerstation Cube 10K

Mophie Powerstation Plus

Nimble Champ Portable Charger

Panasonic BQ-CC87ABBA

Panasonic BQ-CC87AKBBA

Scosche GoBat 10K

TravelCard Plus

Ugreen 20W PD 10000mAh Power Bank

Zendure SuperMini X3

Zendure X5

ZMI PowerPack 10K Ultra Model QB816

8- Green technology and power banks:

Plastic, metal, and other nonrenewable elements, which take decades to disintegrate, make up the majority of power banks’ construction. Therefore, using a power bank for as long as you can without replacing it is one of the most environmentally friendly things you can do. To avoid dents, scratches, and scuffs, handle your power bank gently and keep it in a cable organiser or protective pouch when it’s in your bag.

You should also aim to store your power bank in a cool, dry place (ideally at approximately a 40% charge), as excessive temperatures can permanently harm batteries.

If your power bank does break, there are helpful repair manuals for the majority of devices on iFixIt and Instructables. However, you should recycle it if it can no longer be charged or if it is irreparably damaged.

The majority of Americans regularly recycle their plastic, metal, paper, and cardboard, but less than half (requires subscription) routinely recycle their spent batteries and other electronic debris, or “e-waste.” E-waste that isn’t recycled frequently ends up in a landfill, where it can leak toxic chemicals and heavy metals into the local water and soil. Additionally, it encourages the mining of more raw materials for the production of new devices rather than recovering useable parts from outdated ones.

A few excellent sources for recycling power banks and other e-waste are listed below:

Use searchable databases like Call2Recycle, Earth911, GreenCitizen, or Greener Gadgets to locate e-waste recycling centres in your neighbourhood. While several towns have designated drop-off locations, the majority do not offer curbside pickup for recycling batteries. The majority of power banks and many other household electronics utilise lithium-ion batteries, which may require greater safety precautions than other battery types. Before dropping off batteries to a recycling site, make sure it accepts these batteries.

Watch for e-waste recycling events in your area or consider starting one yourself!

You can recycle by mail by sending in a pre-paid shipping container from TerraCycle, Call2Recycle, or another company.

9- The Contest:

Our previous recommendation for those looking for a power bank that also functions as a wall charger is the Anker PowerCore Fusion 5000. Its rated capacity is 5,000 mAh, and its size and design make it suitable for carrying in a pocket. However, compared to our top option, its connectors (two USB-A output ports and a Micro-USB input connection) are far less powerful.

Lightweight (3.1 ounces), the Flux 4000 mAh Ultraslim Portable Charger is small enough to tuck into a pocket. It comes in a range of colours, has built-in USB-C and Lightning cables, a Micro-USB input connector, a USB-A output port, and these features. The materials all appear fragile, and it’s practically impossible to get the cables back into their slots after charging.

The intelliArmor Scout Max is a master of none and a jack of all trades. It can charge itself using its built-in Micro-USB port and AC socket, and can almost charge any handheld device using its built-in Lightning, Micro-USB, and USB-C cords. However, it’s more difficult than we’d like to remove the cords and connector, and its 10,000 mAh capacity isn’t any better than other of our top picks. Additionally, we were unable to locate any warranty information on the business’ website, so we cannot guarantee for their customer service.

Although the Mophie Powerstation Hub adds Qi wireless charging and has a little higher capacity (6,000 mAh) than the Fusion III model we previously recommended, we don’t believe those features are worth the typical $100 price tag. Additionally, it has a more angular design that is harder to handle and put inside a pocket.

The Mophie Powerstation PD features a pleasantly pocketable design, weighs only 5.2 ounces, and has a gripping surface. While only a few ounces heavier than our SuperMini selection, it delivers much less capacity (6,700 mAh).

Both the Mophie Powerstation Plus (USB-C) and Mophie Powerstation Plus Mini (USB-C) have a modern appearance and are quite small and light. However, the built-in USB-C cables are particularly difficult to insert back into their slots, which we believe would drive the majority of users insane.

The only difference between the RAVPower 10000mAh Power Bank (RP-PB186) and the Anker Redux is that it has rough ridges along each of its seams, which makes it less comfortable to handle. But it would be a terrific alternative if you could purchase it for a lot less money than the Anker model.

With a weight of only 4.1 ounces, the TG90° Portable Charger 6000mAh External Battery Pack is one of the tiniest and lightest power banks we’ve tested. Its mAh capacity rating (6,000 mAh) is even more than that of power banks twice its size. It contains a USB-C input connector and two built-in cables (USB-C and Lightning) that can be pulled into and out of their holsters with ease.

Additionally, it is well made and fairly durable. Despite these benefits, however, we are hesitant to suggest this approach in the absence of extensive testing because, other from its Amazon storefront, the company has no online presence.

The Tronsmart Trim 10000mAh USB-C Power Bank offers a Micro-USB input connector in addition to having the same capacity rating (10,000 mAh) as our favourite SuperMini power bank. We like the appearance and feel of our options instead since we don’t believe an additional (and slower-charging) input option provides a meaningful benefit for the majority of consumers.
