Full Review
The DELTA 2 has been a category benchmark for years, and its longevity is an asset: firmware is mature, accessories are everywhere, and street prices frequently fall hundreds below list. In endurance testing it consistently squeezes more usable runtime from its rated capacity than most competitors.
Its standout feature is expansion. Start with 1kWh; if your needs grow, snap-on batteries take you to 3kWh without replacing the core unit. X-Boost cleverly runs high-wattage resistive appliances (kettles, heaters) beyond the inverter's nominal rating.
Head-to-head with the Anker C1000 Gen 2, it gives up a bit of charge speed and quietness. Buy it when it's on deep discount or when the expansion path matters — both happen often.
Pros and Cons
