12V or 24V for a 2000W inverter? We compare current draw (~170A vs ~85A), cable size in mm², cost and efficiency — and when 12V is fine vs. when 24V is the clearly better choice.
Power & EnergyWhat cable size for a 2000W inverter? At 12V the real draw is ~180–200A — we show why 50 mm² is the bare minimum (70 mm² is safer), how to size the fuse and voltage drop, and how to avoid cable fires.
Power & EnergyMPPT or PWM? We explain the difference, the efficiency (PWM roughly ~70% vs. MPPT up to ~98%) and when the pricier MPPT controller is worth it — including the important V_OC × 1.25 sizing rule.
Power & EnergyOctopus Agile explained: prices change every half hour, the 4–7 PM peak can top 30p and overnight can go negative. We show how the tariff works and how a plug-in battery profits from the swings — realistically.
Power & EnergyMy 2000W DIY solar setup with LiFePO4 leisure battery, Victron MPPT charge controller and a 400 W foldable panel for around £1,050 — built for more usable capacity and expandability than a similarly-priced pre-built, not for beating one on a 2 kWh sticker price. Complete UK bill of materials, step-by-step wiring, and an honest side-by-side with EcoFlow DELTA 3 Plus and Jackery Explorer 2000 v2.
Power & EnergyHow my ~£530 portable battery + Tapo smart-plug setup uses Octopus Agile's overnight cheap rates (sometimes negative pricing) to shave my electricity bill by roughly 10–15% — no DNO paperwork, no MCS installer, no G99 application.
MobileThe best budget smartphones in the UK for 2026: Google Pixel 10a (7 years of updates), Samsung Galaxy A57 (6 years), Nothing Phone (4a) Pro as the British-brand hero, and the £219 CMF Phone 2 Pro under £250 — with PSTI Act minimum-support-period context.
KitchenThe best air fryers in the UK for 2026: Ninja Foodi MAX Dual Zone AF400UK, Philips 3000 Series Dual Basket, Russell Hobbs Satisfry Medium, Tower Vortx and COSORI compared — with UK energy-cost-vs-oven calculation and Which?-aligned picks.
KitchenThe best espresso machines in the UK for 2026: Sage Bambino, Sage Barista Express Impress, De'Longhi Magnifica and Gaggia Classic Evo compared — with cost per cup as the buying argument.
Smart HomeThe best robot vacuums in the UK for 2026: Dreame X60 Max Ultra, Roborock Qrevo Edge, Eufy E25 Omni and Shark PowerDetect compared — with the dock and UK carpet as the deciding factors.
