Who is ZOOMBROS?

ZOOMBROS is not a well-known brand like but surely it is one of the fast growing 3rd party sellers on Amazon.com, operated by Shenzhen New Energy Co., Ltd. Apparently, they are a private label company selling the “same” power station (with different colors) that is being sold to multiple parties such as TBD.

No company website were found online, however, we came across a site where you can register your Amazon purchase for lifetime warranty. We’ll cover this in more details further down the page. For now, let’s look at what they have to offer in this compact powerful box.

About ZOOMBROS 330W Portable Power Station

In a nutshell, the Zoombros power station is a compact power-to-go package equipped with a 288.6 watt-hour rechargeable lithium battery that weights only 7.6 pounds. It has enough juice to power your 70W Black and Decker mini fridge for 4 hours and recharge your iPhoneX around 27 times.

It features seven DC charging ports, including two 12V/5A ports (5.5mm) , one 12V/10A port, three USB ports with QuickCharge 3.0 compatibility, and one Type-C USB port.

There’s also a 110V pure sine wave AC outlet rated at a max of 330W, a standard ac outlet similar to what you have at home. You don’t have to worry about your thousand dollar CPAP machine being damaged by modified sine wave anymore.

Just like their direct competitor Jackery, each section of ports can be turned on or off with a dedicated button.

No more guessing. Their well thought-out backlit display provides an exact percentage battery charge and input/output power wattage being processed.

No more fear. Thanks to their built-in 5W wireless phone charger, you don’t have to sweat again if you ever forget to pack your charging cable.

Is this the best portable power station? Listen up…

In my complete field test, I found a few features are missing and things I didn’t like. They’re not “deal-breakers”, I’ll go over each of them further down the page.

Feature Highlights

Let’s do a rundown of the main features that the ZOOMBROS Portable Station Generator comes with, so you can figure out whether or not this is a suitable device for you.

Wireless Phone Charger

Thanks to their built-in Qi wireless charging station, you can leave your charging cable at home now. It’s a great add-on feature not found in many portable power stations.

Bear in mind that this is only a 5W (5V/1A) wireless charger, it won’t charge up your phone in a few hours like your regular charging cable plugged to your wall outlet. However, it’s pretty good for everyday needs in my opinion. It’s a great addition not found in many competing products.

Any Qi-enabled devices such as Samsung Galaxy S9,S9 Plus, Note8, S8, S8 Plus, Samsung S7, S7 Edge, Note 5, S6 Edge Plus, iPhone X, iPhone 8, iPhone 8 Plus will be supported.

Wireless vs Wire phone Charging – How fast is it?

We only performed this charging comparison speed test with an iPhone X. As you can see the QC 3.0 USB port gave a 10% boost in 12 mins, whereas, it took 20mins when using the Qi wireless charger.

So, expect the wireless charging station to fully charge your phone twice as much longer than using a regular charging cable. In fact, this wireless charger could be your life-saver if you ever leave your charging cable behind at home.

Size, Weight, and Overall Portability

Although not the most essential feature, you may like the ZOOMBROS Portable Station Generator for its high level of portability.

This generator is designed for portability. You can easily pop it in your car or even your camping backpack, and carry it to your campsite. It’s small, lightweight, and perfect in terms of portability.

** The red rubberized undercoating prevent it from slipping out of your hand when you carrying it around.

The bottom has four rubber feet to hold it off the ground.

This generator measures 8 x 6.1 x 6.5 inches, making it relatively small. It weighs just 7.6 pounds, making it very lightweight.

It also comes with a folding plastic handle for easy carrying, it really feels good in the hand.

Multiple Powering Options – Charging 9 Devices Simultaneously

You’re probably wondering what the ZOOMBROS Portable Station Generator can be used for. Keep in mind that it is not designed for 330W or more, which means it is intended for smaller electronics. Although this is quite an impressive unit considering its small size, it’s not designed to power large appliances.

ZOOMBROS 330W Power Station Review 7
  1. DC 12V/5A (5.5mm) x 2 and 12V/10A (Car Port) x 1
  2. USB 3.0 x 3 and USB Type-C x 1
  3. 110V Pure Sine Wave AC
  4. Wireless Charging 5W (Qi Compatiable)

That said, this is still quite a versatile power station.

It comes with an AC outlet (pure sine wave) rated for 300W that can charge things like phones, laptops, small drones, very small televisions, and more.

It also comes with dual DC outlets (12V 5A), so you can charge or power a litany of devices and small electronics.

There’s also a car port (12V 10A) to run a small fridge and even something like a CPAP breathing machine.

This unit comes with a wireless charging function that can charge compatible phones and other small electronics without needing to plug anything in.

 

Built-in Lithium-Ion Battery

The battery pack inside this unit made up of 30pcs of 18650 lithium-ion battery cells with high energy density battery that can be cycled up to 800 times.

It can charge a basic smartphone about 24 times, a tablet about 7 times, a laptop about 5 times, and can even power a small car fridge for a few hours.

You can use it to run a CPAP machine for about 3 nights; you can run small camping and fishing lights on it for nearly 12 hours.

Three Ways To Charge

Now that we have covered what the ZOOMBROS Portable Station Generator can power and/or charge, let’s talk about how to charge the unit itself so the battery pack is ready to go when you need it.

What is really convenient about this unit is that there are three ways of charging it. You can use a standard wall outlet to charge it in about 6 hours. You can use the port in your car (using your car battery) to charge it in about 8 hours.

You can also use any solar panels above 100W for charging. We think solar charging is excellent because you can still load up the battery pack when you are camping. All you need is the solar panel and a few hours of sunlight.

ZOOMBROS 330W Power Station Review 10

1. Charge it with the provided 60W AC power adapter (15V/4A) directly from a wall outlet.

2. Charge it from your 12V cigarette lighter in your car with provided car charger cable.

3. Charge it with your choice of solar panels that are rated above 100W.

Note that the charging time may vary. With input power above 60W, the charging time should be between 5-6 hours.

Pass Through Charging

Can you recharge the power station while charging you devices at the same time? Well, it depends.

ZOOMBROS 330W Power Station Review 11

You can charge it while using the 12V DC outputs, USB 3.0 and USB Type-C outputs.

However, the AC inverter turns off itself once you start charging it via the 15V/4.0A DC input connector. In other words, this power station only has DC pass-through charging.

Durability and Safety Measures

The ZOOMBROS Portable Station Generator is built durable enough, and it has quite a solid shell, although that said, don’t get it wet.

In terms of safety measures to keep you safe and keep it from breaking down, it comes with an advanced BMS system; over-voltage protection, over-current protection, and over-temperature protection are integrated into the ZOOMBROS Portable Station Generator to ensure maximum longevity.

What are inside the box?

ZOOMBROS 330W Power Station Review 12
The ZOOMBROS 330 arrived well-packaged and safe. It uses eco-friendly packing materials including the inserts made of recycled cardboard. The owner’s manual uses non-toxic materials too. First impression is great to me.

Package Includes

The User Manual

ZOOMBROS 330W Power Station Review 13

​The user manual covers only one language – English. The whole user manual is only seven pages long; it is precise and well-written. Instructions are simple to follow and customer support information is also included. In fact, this portable power station is pretty much plug-n-play and not much set-up is required.

Hands-On Field Tests

The goal of our field test is to verify the ZOOMBROS330 can deliver what it was said in the user manual at a high level. We do not have the resources to perform longevity test or any of the industrial compliance & safety standard such as FCC and CE as specified in the specification.

Battery Capacity – How much power can you get?

There are many ways you can measure battery capacity of the 18650 3.7V Li-Ion battery pack in this compact unit. For instance, you can use a $50 battery capacity tester on eBay or simply use a power resister, cooling fan, and a power water meter as shown below.

ZOOMBROS 330W Power Station Review 14
ZOOMBROS 330W Power Station Review 15

Equipment used in this test:

  1. 25W 10Ohms cermet resistor
  2. 12V DC cooling fan
  3. IFLYRC RC Watt Meter Analyzer

Depending on the power resister you choose, it will take hours to deplete the Li-Ion 288Wh battery pack down to almost zero watt. In my test case, it took 12 hours to drain all power from this battery pack.

Surprisingly, the measured battery capacity is ~306Wh which is a bit higher than 30 x 9.62Wh = 288.6Wh as claimed in their specification.

Recharging – How long does it take to charge ZOOMBROS 330?


Now, let’s find out how much power and how long it’ll take to fully charge the “288.6Wh” Li-Ion battery pack. In this test, we re-charged it with the provided 60W AC power adapter because from my past experience it should take the least amount of time and the result should be relatively consistent comparing to charging by a solar panel.

Equipment used in this test:

  1. IFLYRC RC Watt Meter Analyzer
  2. Bench top DC power supply 30V/5A
ZOOMBROS 330W Power Station Review 16
ZOOMBROS 330W Power Station Review 17
ZOOMBROS 330W Power Station Review 18

Using our bench top DC power supply, we discovered the ZOOMBROS has a fixed 52W input voltage regulator which makes their fastest charging time to be about 300Wh/52W = 6 hours.

It doesn’t matter you have a 1000W solar panel or 60W AC power adapter, the charging time will be about 6 hours, period.

What Can You Power with ZOOMBROS 330?

According to the technical support at ZOOMBROS, you can run any appliances rated below 330W. In other words, stick with the basic low end electric application such as charging your phones, laptops, CPAP machine or even a small car fridge (60W).

Do not expect this compact power station to power your hair dryer, kettle, coffee machine or heat gun (basically not appliance that generates lot of heat). Take a look at this BLUETTI 2000W portable power station if you really need to brew your fresh cup of coffee in the wood.

Example of Supported Appliances:

Free Lifetime Warranty

ZOOMBROS 330W Power Station Review 20

Yes, you heard me right – Lifetime Warranty.

This is one of the biggest bonus feature that really surprised me a lot. Most direct competitors only offer 12 to 18 months limited warranty but ZOOMBROS is able to offer customers purchased from Amazon with this hassle free lifetime warranty.

All you need to do is to register your product at zoombros.vip and you will also receive a $10 Amazon gift card for any items. (You just have nothing to lose in this awesome deal.)

Conclusion – Who Should Buy it?

I’m no stranger to portable power stations and solar generators, so I didn’t think I would get excited about portable power station. It turned out I was wrong.

The ZOOMBROS 330 Portable Station Generator is more than enough for a several-day camping trip, and it can really save you in an emergency situation. It’s a perfect device for entry level consumers who need something that’s very compact and lightweight. It can charge your phone, tablet, camera, LCD TV, or even a small fridge (40W) for 7 hours. Basically, any low end DC appliances that are rated below 330W. The primary use is camping and other related activities.

I have tested many power stations and what sets this charger apart from other models is the Qi wireless charger and its backlit LCD display for providing insightful information about the control unit and power consumption status. With the built-in safety BMS unit and hassle free lifetime warranty, it really make the ZOOMBROS 330 a worthy buy.

That’s it for now! If you’ve found this review useful, please share this article with your buddies and let us know in the comments below or leave a comment on our social pages.

F.A.Q

It comes with a standard 18 months from date of its original purchase. You can get lifetime warranty if you register at zoombros.vip.

PWM. It has a fixed 52W PWM solar charge controller. No matter you’re using 100W, 200W or even a nuclear reactor, the charging wattage always max out at 52W.

It contains a battery pack with 30pcs of 18650 lithium-ion battery cells with high energy density, battery cycles up to 800 times.

We recommend you to use a 100 watt portable solar panel such as Allpowers 100W Foldable or Renogy 100W Flexible. Using any higher power panel will not reduce the charging duration because the maximum input wattage is fixed at 52W.

It depends on the power wattage of your devices. In general, the formula is Operating Hours = Total WattHour x 85% / Device Power. For instance, you can run a 12″ MacBook (40Wh) for 288.6Wh x 0.85 / 40W about 6 hours. If you have a desktop running at 245Wh, it can power it for 288.6Wh x 0.85 / 245Wh about 1 hour.

No, it’s not waterproof.

No. According to TSA you can bring a power bank up to 100Wh with you. (Note: The final decision rests with the TSA officer on whether an item is allowed through the checkpoint.)

It depends on how much direct sunlight your are getting. In general, a 100W solar panel with direct sunlight, it should fully charge it in 5-7 hours.
