Which is the Yr’s Greatest Energy Station?


Background and Introduction 

You might not have observed with every little thing else occurring, however over the previous yr moveable energy stations have turn into a scorching matter of debate. A ton of latest merchandise have come out not too long ago from established manufacturers like Jackery, EcoFlow, and Bluetti. Just a few have gotten their begin by way of crowdfunding, just like the Bluetti EP500 (5.1 kWh/3 kW) which generated 3.1M USD on Kickstarter in Could and the EcoFlow DELTA Professional (3.6 kWh/3.6 kW) which is at the moment aiming for a July Kickstarter launch. There are some new gamers coming into the market, as properly, just like the brand-new Mango Energy Union (6.9 kWh/4 kW) which, in keeping with its web site, is meant to hit Indiegogo in August. At present, we’re going to take a deep dive into two of those – the Mango Energy Union and the EcoFlow DELTA Professional – to see how they stack up in opposition to one another. 

Neither of those energy stations have formally launched but, so all of the specs on this article come from their respective web sites.  
(EcoFlow Delta Professional; Mango Energy Union ) 

Earlier than leaping in, it’s necessary to notice that the Mango Energy Union integrates each a transportable energy station and a bigger house module right into a single gadget, so it’s not a very apples to apples comparability subsequent to the EcoFlow DELTA Professional. Nonetheless, for anybody available in the market for an influence station in 2021, this side-by-side look ought to be useful. 

Battery Capability 

The complete Mango Energy Union boasts a formidable 6.9 kWh capability whereas its removable module – the so-called “Energy Transfer” – clocks in with 2.3 kWh. Each use excessive class EV Polymer NCM Battery Cells which have 38% better vitality density, and are able to working in a broader vary of temperatures than conventional LFP cells.  

The EcoFlow DELTA Professional’s 3.6 kWh capability beats out the Energy Transfer, however can’t examine to the entire Mango Energy Union bundle. EcoFlow has not but launched the precise particulars of its battery cell, however we assume it is going to ship better capability than its predecessor. 


The Mango Energy Union might be expanded to as much as 10 units working in parallel for a whopping 69 kWh and 40 kW output. The EcoFlow, then again, helps a decent scalability as much as 6 units. If customers embrace an expandable battery pack, the finished configuration ought to ship a complete of 25 kWh. No details about the output functionality.

Potential Backup Time

When scaled to its full dimension (6 units in parallel) the EcoFlow claims 13 days of emergency house energy or 20 hours of every day use. Mango Energy has not but talked about specifics for his or her potential backup time, however have steered their gadget may energy a house for weeks within the occasion of an outage. This appears to be a sensible declare for customers who buy the utmost 10 units for 69 kWh capability.

If a person was restricted to just one unit of both gadget, although, the Mango Energy Union (6.9 kWh) would win arms down in opposition to the EcoFlow DELTA Professional (3.6 kWh).


The Mango Energy Union has better battery capability per unit and better scalability potential.

Output and Charging

Mango Energy Output Ports


The Mango Energy Union helps 16x output sockets whereas the EcoFlow most likely helps 15x ports (based mostly on obtainable pictures).

As you’ll be able to see within the desk above, the Mango Energy Union simply barely edges out the EcoFlow for whole variety of ports, however the EcoFlow helps each DC and RV ports. The principle sockets, like AC/USB-A /USB-C/wi-fi charging, are very related.


The Mango Energy Union helps 3 kW MPPT photo voltaic charging (12V-250V) and three.3 kW wall outlet charging. This enormous vary in photo voltaic charging functionality means you’ll be able to join the gadget to both roof photo voltaic panels or moveable photo voltaic panels.

The EcoFlow makes use of X-Stream charging expertise that allows 3 kW wall charging. It additionally helps an astounding 4.2 kW for photo voltaic charging when you’ve got sufficient panels. It’s as but unclear whether or not the EcoFlow might be charged by way of roof photo voltaic panel, however we suspect it should. In any other case, you’d have to lug round 42 100W photo voltaic panels to attain these numbers in a real-world state of affairs.


Each units have the primary sockets you’ll want and the Mango Energy Union has a slight benefit within the variety of ports, however the EcoFlow DELTA Professional presents better variety with each DC and RV ports.

Concerning charging functionality, each manufacturers ship respectable speeds. The EcoFlow DELTA Professional seems prefer it presents a lot better photo voltaic charging functionality, however it is going to solely be helpful if it connects to a roof photo voltaic system.

Design and Dimension

Relating to design, the Mango Energy Union is in a category of its personal. It includes a brushed steel pores and skin and sensible but clever ambient lighting standing indicator that make it look extra like a bit of recent artwork than a battery. Although it may possibly most likely be made to match many inside design types, it actually wouldn’t look misplaced in a gallery. The whole Mango Energy Union bundle, together with the removable, moveable Energy Transfer, has an general dimension of 17.6 * 13.6 * 26.7 inches. That will sound massive, but when we take into account its whole capability (kWh/m3,) it’s fairly spectacular, most likely probably the most compact available in the market. This can be because of the Polymer NCM Battery Cells it makes use of versus the conventional 18650 cells.

Its removable portion, the Energy Transfer (2.3 kWh/2 kW), is 17.6 * 13.6 * 11.4 inches, a comparatively good dimension for the moveable energy station market.

The EcoFlow has saved a really industrial design, just like its earlier DELTA mannequin.

The corporate has not but launched the precise dimension of the battery, however with its elevated capability and performance, it’s affordable to imagine that will probably be a lot bigger than the earlier DELTA, which was 15.7 * 8.3 * 10.6 inches.


With regard to design, the Mango Energy Union comes out on high. It’s obtained a cool, fashionable look that might undoubtedly slot in a swanky front room, however setting appearances apart, the truth that it consists of each a transportable and a house energy station make it a uniquely progressive product. The EcoFlow, nevertheless, ought to be extra fashionable amongst those that want an industrial look, and could be completely at house in a storage.


The Mango Energy Union consists of 2 components: the Energy Dwelling for house use, and the Energy Transfer for outside off-gird life. It really works as a house backup energy provide, shops inexperienced vitality like solar energy out of your roof, and may seamlessly energy delicate electronics so there’s no break in energy in case of an outage. The Energy Transfer might be taken travelling or out into the sphere for skilled outside work. The complete gadget has quite a lot of settings, together with Again Up Energy Mode (prioritizes vitality storage to stop shortages), Time-Based mostly Management Mode (shops and consumes energy based mostly on peak/off-peak instances to save lots of in your electrical invoice) and Economic system Mode (prioritizes inexperienced vitality use when linked to a photo voltaic system).

The EcoFlow, with its all-terrain wheels, extra rugged case, and telescoping deal with, undoubtedly serves a job in powering outside life, however on the subject of house use, notably if there’s an emergency, you most likely wouldn’t need to depend on it too closely except you obtain 6 of them and had them working in parallel.


Each merchandise can undoubtedly ship good service for outside dwelling, however the Mango Energy Union looks as if a greater wager once we’re speaking a few house backup energy supply. It makes extra sense to check the Mango Energy Union to a Tesla Powerwall on this respect, and we hope to place these two head-to-head in a later article.


The Mango Energy Union can join by way of both Bluetooth or Wi-Fi with an included app that allows distant management and OTA upgrades. The app additionally data your vitality use stats and offers you notifications and alerts when needed. It additionally generates a report displaying your inexperienced vitality use and carbon footprint.

The EcoFlow DELTA Professional can solely be managed by way of its built-in panel, which is nice sufficient once you’re utilizing it as a transportable battery.

Worth and Availability

Each merchandise have launched by way of crowdfunding platforms. The Mango Energy Union launched on Indiegogo whereas the EcoFlow DELTA Professional not too long ago switched to Kickstarter. The Mango Energy Union has a retail value of $5699 and is at the moment providing an early chicken value at $3999 and EcoFlow DELTA Professional has not but launched a value. Right here we additionally add Tesla Powerwall for a comparability.

We’ve priced the 2 of them out when it comes to battery capability as proven within the desk under. I’ve to say, the Mango Energy Union’s pricing is sort of aggressive, particularly for a brand new model. Both manner, each of those batteries are moderately affordable.

A Little Additional

There are a number of little issues we didn’t fairly get an opportunity to say.

First off, we actually want to emphasise the usefulness of the EcoFlow DELTA Professional’s all-terrain wheels and telescoping deal with. It might not sound like a lot, however once you’re carrying a pack in your again and mountain climbing towards your campground, you’re undoubtedly going to understand how straightforward this moveable energy station is to maneuver round.

The Mango Energy Union, then again, actually speaks to the eco-warrior in me. For each 48 kWh of photo voltaic vitality that flows by means of this gadget, the corporate vegetation one other tree in a single our nation’s nationwide parks by means of one thing they name The Forest Plan. Provided that the Mango Energy Union boasts a 69 kWh capability and claims to be rechargeable for 60,000 cycles, which means you might probably “earn” 86,250 bushes. I like that concept.

Both manner, although, if you happen to select one in all these or another energy station and also you energy it by way of some type of inexperienced vitality, whether or not it’s wind, nuclear, photo voltaic, or the rest, you’re doing the world a favor. Thanks.
