Allpowers BS2500 Pro
A capable 2600Wh plug-and-play balcony battery that has done well in Europe, but not yet sold through a US store or Amazon.com as of 2026.
Characteristics
- Capacity: 2600 Wh (LiFePO4), 2400W hybrid
- Solar: Dual MPPT, anti-backflow protection
- US status: No Amazon.com listing, no confirmed UL3700
- 2600Wh hybrid battery, not yet confirmed for the US
Detailed overview: Allpowers BS2500 Pro 2600Wh balcony solar storage system
The Allpowers BS2500 Pro is a plug-and-play balcony solar storage system that has built a solid reputation in Europe: 2600 Wh of LiFePO4 capacity, 2400 W of hybrid grid and off-grid power, a dual MPPT solar input for panels facing different directions, anti-backflow protection, and an IP65 rating for outdoor mounting on a balcony or facade.
For the US market specifically, our research found a real gap between the hardware and actual availability. We could not find this product listed anywhere on Amazon.com. Allpowers' own storefront for the BS2500 Pro, iallpowers.eu, advertises free shipping across EU countries and, separately, to Ukraine, but makes no mention of shipping to the United States. We also found no confirmed UL3700 certification, the standard now used to clear plug-in solar storage equipment for the US market, unlike EcoFlow's Stream Ultra, which currently carries that certification and Utah-specific self-install marketing.
None of this reflects badly on the hardware itself, which remains a well-reviewed, capable balcony battery where it is actually sold. It means that, as of this review, a US buyer's realistic path to this exact unit runs through importing from a European retailer at their own risk on shipping cost, customs, plug compatibility and warranty support, rather than a simple domestic order with US customer service behind it.
Readers specifically looking for a plug-and-play solar battery with confirmed, straightforward US availability should compare this product against EcoFlow's Stream Ultra, reviewed separately on this site, which currently has genuine Amazon.com and US-store presence even with its own stock and state-by-state limitations.

Our tester's review: Julien De Jurquet
On hardware alone, the BS2500 Pro earns its strong European reputation: 2600 Wh of LiFePO4 storage, 2400 W of hybrid grid and off-grid power, dual MPPT for panels facing different directions, and an IP65 rating built for a balcony or facade. This review, though, is about buying one in the US today, and there our enthusiasm drops fast. We found no listing anywhere on Amazon.com, and Allpowers' own storefront for this product, iallpowers.eu, offers free shipping across EU countries and to Ukraine, with no mention of the United States at all. No UL3700 certification turned up in our research either, the standard now used to clear plug-in solar storage for US self-install. None of this means the hardware is bad. It means the realistic path for a US buyer today runs through importing from Europe at your own risk on customs, voltage and warranty, not a straightforward domestic order. Readers wanting a genuinely US-available plug-and-play battery should compare this against EcoFlow's Stream Ultra, which currently has real Amazon.com and US-store presence.
