Which large battery bank to choose? We compare the DJI Power 2000, Bluetti AC300+B300 and EcoFlow Delta 3 1500.

The recent summer thunderstorms that moved across the Baltics were a reminder of how unexpectedly electricity can be lost – be it in Estonia, Latvia or Lithuania. Often the outage is short, but sometimes it lasts for hours or longer, which can mean that your fridge, lights or internet are down just when you need them most.

At the same time, there are more and more people who simply want more freedom and independence – to go on a road trip in a camper van, camp in the woods for a week or work outdoors in the summer without looking for a plug. That’s where big battery banks, or battery stations, come in, which are much more than the usual “phone charger in XXL size”. They are small power stations that can power lighting, tools, a cooker or fridge, for example.

Why is such a battery bank necessary at all?

• Back-up at home – keeps work and life running when the mains power goes out.
  
• On a hike or in a caravan – you get light, music, a hot drink and even an electric trike.
  
• Professional outdoor work – lighting and sound equipment, drones, cameras need stable power.
  
• A greener lifestyle – combined with solar panels helps reduce electricity bills and dependence on the grid.
  

Three solid choices: DJI, Bluetti and EcoFlow

🔌 DJI Power 2000 – a modular system, especially good for drone use.

DJI is renowned for its world-class drones, but their DJI Power range also offers cutting-edge power stations. The DJI Power 2000 is a powerful 2048 Wh LFP battery pack that delivers 3000 W of output – meaning you can safely plug in a fridge, router, light or drone charger all at the same time.

• Particularly useful for drone pilots: thanks to DJI SDC ports, you can charge DJI drones directly, without the need for adapters.
  
• It can be upgraded with modules up to 22 kWh, making it a real mini-electric power station.
  
• Weight starts at ~22 kg, which is reasonable for this power.
  

Bluetti AC300 + B300 – the home backup with the largest capacity

Bluetti is one of the best known manufacturers of power plants, especially for domestic backup power. The AC300 is in fact a powerful inverter (3000 W continuous, 6000 W peak) plus a B300 module (2764 Wh). So you can increase the system up to ~12 kWh using up to four battery modules.

• Ensures automatic power supply (UPS) with less than 20 ms delay, so your computer or router does not shut down.
  
• Can be charged in seven different ways, including from solar panels or a generator.
  
• Cons: the whole system with batteries weighs ~51 kg, so rather stationary.
  

EcoFlow Delta 3 1500 – fast, compact and versatile

EcoFlow is renowned for its fast charging – the Delta 3 1500 charges fully in less than 90 minutes. With its 1536 Wh LFP battery and 1800 W continuous (3600 W peak) output, it’s perfect for home, camping or hiking.

• Thanks to IP54 dust and splash protection, it’s not afraid of rain or hiking trails.
  
• Weighing only ~16.5 kg, it’s easy to carry.
  

When a big one is not needed or the budget is limited

If that much power seems like overkill or the price is too steep, it’s worth checking out the smaller models in the same DJI Power family:

• DJI Power 1000 – half the size (around 1024 Wh), but perfectly adequate for camping, a small event or just to keep the lights and router on.
  
• DJI Power 500 – Lightweight, ideal for charging drones or cameras in the wild, DJI SDC port is also available here.
  

So you get the same quality, DJI ecosystem and in-app tracking, but at a much lower price.

Which model is right for you?

To sum up

Whether you’re looking to be prepared for a power cut, a long trip to the great outdoors, or simply a more independent and environmentally friendly life, a proper battery bank will give you the peace of mind and freedom you need.
