Caveats
- The fan sometimes runs loudly with AC enabled and nothing plugged in.
- Drained a full battery in about 1.5 days idle with AC and Wi-Fi left on.
- The beeper cannot be disabled in the app.
- The display over-reported load in testing (about 350 W shown at a measured 250 W), so the runtime estimate is rough.
Affiliate link: if you buy through it, the merchant pays us a commission at no cost to you; that commission pays for the cart tests behind every code here. Price, availability and each code were checked on the merchant's own US store on the dates shown; they change, so the store's checkout is the source of truth. Full disclosure.
