I bought a different brand (Yedi) that included a similar hand pump and similar bags, that was 1000w for $85 via Amazon half a decade ago but it is no longer available. Still use the sous vide but the bags/pump sucked, ended up buying a low-end vacuum sealer and a bunch of legit bags which were night and day. Looks like the sealer is currently on sale: https://smile.amazon.com/gp/product/B08F72TY67/ref=ppx_yo_dt_b_search_asin_title?ie=UTF8&psc=1
