More features

• TRIPLE-ACTION HEAT BRACE FOR BACK PAIN RELIEF – IKEEPFIT MAXwarm 4.0 combines deep heat, gentle vibration, and brace-level lumbar support in one wearable belt. The extra-wide heating zone surrounds your lower back and abdomen while the vibration relaxes tight muscles; the X-shaped brace and dual elastic strap adds lumbar support and keeps everything snug and on target, helping relieve lower back pain, and discomfort related to disc herniation, arthritis, sciatica, scoliosis, and other spine issues when you sit, stand, or work.
• MAXwarm Technology — FASTER HEAT, GREATER WARMTH, WIDER COVERAGE- Its extra-wide graphene heating area (2X typical) warms both your back and abdomen in 5 s and spreads deep, even heat to release back tightness and reduce soreness—so working, commuting, and resting feel much easier. NTC smart temperature + safety sensors + 20-min auto-off prevent hot spots and keep muscle comfortable. Dual front/back zones target cramps or lower-back relief double as needed(turn the front zone off when you only want back relief).
• CORDLESS & PORTABLE HEATING PAD – Unlike typical heating pads with the hassle of cords or only 5000 mAh bulky power-bank packs, IKEEPFIT MAXwarm 4.0 uses a built-in 8000 mAh battery for true wireless freedom. Wear the front zone over your stomach for menstrual cramp relief; the broader area warms more angles than other heating pads, so warmth feels steadier and you’re more comfortable. Can be used on other body parts like hips, legs, or shoulders when tied snugly. Includes two extension straps（12"/28"）. Unlike a USB heating pad, it needs no cable or port.
• BRACE-LEVEL LUMBAR SUPPORT WITH 3D CURVE-FIT DESIGN – 3 reinforced metal support bars and 2 ultra-elastic bionic straps form an ergonomic “X” brace that stabilizes your lumbar area, encourages better posture, and reduces strain when you sit or stand for long hours or lift. Firm outside, soft inside: the 3D curve-fit design hugs your back comfortably under clothing instead of digging in. Ideal for office workers, drivers, warehouse staff, nurses, and parents who need extra support through the day. Adjustable belt fits most 30"–68" waists (41" base + 12"/28" extensions).
