With the possibility for massive expansion the EcoFlow DELTA Pro can be customised to meet your energy requirements. Along with being the world’s fastest charging portable power station the Delta Pro boasts a whopping 3.6kWh battery.

Battery Capacity of the EcoFlow DELTA Pro

One of the many features of the EcoFlow DELTA Pro is its battery capacity, 3.6kWh which can be increased by adding additional Smart Extra Batteries. With just two Smart Extra Batteries, you can increase your battery power from 3.6kWh to a massive 10.8kWh.

If you are looking for even more battery capacity the DELTA Pro can be expanded to an incredible 25kWh. Enough to power your home for 13 days of emergency power (Emergency home use: 1.88kWh/day (4 lights, fan, router, laptop, smartphone) Daily home use: 29kWh/day (based on users’ average daily electric consumption in 2019 – data provided from EcoFlow).

Is the EcoFlow DELTA Pro Portable?

Moving power to where you need it is an important consideration when choosing a portable power station. The EcoFlow DELTA Pro has two sturdy wheels at the rear and a telescopic handle at the front. This makes moving the DELTA Pro around a total breeze, whether it be around the house or on your outdoor adventures. The retractable handle folds away neatly at the front so you wouldn’t know it was there. The Smart Extra Batteries also has these features so you can easily move the power to where its required.

Green Clean Renewable Energy Via 1600W of Solar Charging.

You can use clean green renewable solar energy to charge Delta Pro in just 2.8-5.6 hours (4 x 400W panels). DELTA Pro has a wide voltage range from 11-150V, which makes it compatible with 90% of third-party solar panels with MC4 connectors. And when the weather gets unpredictable, the smart maximum power point tracking (MPPT) automatically adjusts, maximising your solar generation at any time of the day.

When will I receive my order?

In most cases, a product on our website will give you an indication of the current stock availability, but shipping is not uniform for all products. We maintain fantastic relationships with all of our suppliers and we aim to get products to customers within 3 business days of the order being taken. This availability is based on information from our suppliers and from sales and supply patterns. The availability information given is a guide only and not a guarantee as there are external factors that we may not have control over.

Coronavirus Update – UK couriers and transport companies will not currently guarantee delivery times and we are seeing a slight delay in deliveries – please bear this in mind when ordering.

Specialist Couriers – Some items such as the larger portable power stations are sent by specialist courier as standard couriers will not accept them. These specialist couriers are very reliable but sometimes don’t have tracking or timed delivery.

Split deliveries – We sometimes need to send orders for more than one item by different courier networks (portable power stations for example) – so you may receive items at different times.

1500rpm machines or larger diesel gensets however are typically priced on application and all depend on the destination. We will be happy to quote on any large diesel generator and discuss your needs over the phone or via email.

Most orders placed before 12pm on a business day will be shipped from our suppliers on the same day provided the product is in stock. If you need to be certain an item is in stock and available, or if you need a lead time, it’s worth calling our sales team on 01329 722390. Pricing for extended shipping areas like Northern Ireland, the Scottish Highlands and outlying Islands, Outer Hebrides, Channel Islands, Isle of Man, Scilly Isles, and other postcodes not considered as UK mainland can be obtained also by calling our offices.

Please note that the processing of a payment and acknowledgement email does not constitute a legally binding contact. In the case of mispricing, changes in stock quantity, or if we believe the machine will be misused, we reserve the right to cancel the order and provide a full refund.

Heavy Items

You will be contacted by phone after ordering a larger item to confirm a delivery date before your order is dispatched. Large or heavy items are dispatched through a pallet network, so if we can’t get in contact with you, we may be unable to send out your item on a next day delivery. Please be sure to include a working phone number with your order.

Heavy items will require the recipient to make arrangements to take delivery of the goods and may require the recipient to help the courier unload the item. For items that are delivered on a pallet the courier will leave the pallet as close to your door as possible.

1500rpm diesel generators will require forklift (or similar) offloading; if this is not available then we can arrange a Hiab offload at an additional price – please call us to discuss any delivery requirements.
