BALDR Portable Power Station 500W, 519Wh Outdoor Solar Generator (Solar Panel Optional) Mobile Lithium Battery Pack with 1.

Bought ours almost 1 year ago and have used it on 3 or 4 boondock camping trips without any issues. We've been able to charge 2 phones and run 1 CPAP (on 12v DC) for 3 nights, but it'll kick off late into the 4th. I use my humidifier on low. Typically I will charge it with a 200w solar panel on the 3rd day (output split between coach batteries and the Baldr) but it was too cloudy and hot on one trip to charge, plus we had a small fan going before bed. It killed it early into the 3rd night. Right when I was finally getting to sleep. Allowing more watts for charging would get this unit to the next level. As long as there's sun. I'd buy this brand again, but I'd go bigger. Of course that means more weight. Until battery technology improves, this is nice compromise. Easy to move from place to place and fits nicely next to our bed. Hopefully I won't need to buy another for several more years.

Worked fairly well until a week ago. After in house ac charging both anderson and dc inputs stopped working. Several days later unit is dead. No policy on replacement, even though bout less then year ago

I purchased both the Baldr 500 power bank and the 120 watt solar panel because i wanted to make sure they were optimized for charging. So far so good. Have only used twice, once in the backyward and once on a day trip to the mountains. I really didn't expect the solar panel to charge the battery as efficiently as it does. It took the power bank from 48% to nearly full in 4 hours. It didn't hit 120 watts, but it was consistently charging at about 80-90 watts. I plan to get a second panel and run them in series. DC output barely makes a dent in the battery while I was able to drain over 1/3 while charging my laptop via AC outlets. As other reviews have mentioned make sure you turn the unit off when not in use. The unit seems rugged enough and well built.There's not much to improve but i do wish there was a spotlight on the side and dust covers on the outlets. I could leave the unit in the car or in a tent to avoid dust in the outlets but id rather have it outside where we are without worrying about dust getting in. Otherwise i have no regrets with this product. Let's see how it holds up.

Everything ok, just cant charge my phone. I been contacting seller see i can get solutions for the charge issue.Waiting for response.

If you live in areas hit by disasters (hurricanes, tornadoes, fires, or just plain power outages), I cannot stress how important it is to be prepared for emergencies. There has been an increase in people taking emergency preparation more seriously.IN A NUTSHELLLike the majority of battery power stations, this Baldr one does not produce much noise like a gas generator. As such, it can be brought to camp sites that have noise restrictions and also can be used indoor in an enclosed area. No worries about carbon monoxide poisoning. We use the battery to charge phones, fans (the hot summer heat can be unbearable), a mini humidifier, and multiple light bulbs for the kids to run around at night. The built-in light came in handy too for cooking or inside the tent.519Wh is enough to power a car freezer (like Dometic, Alpicool, Foho, Domende, etc) for about 1 day, depending on ambient (surrounding) temperatures. It can then be charged from the AC wall, car DC cigarette port, or solar panels via its built-in Anderson Power Pole (APP) connector. Keep in mind that the AC output outlets use up 7W more power than the USB/DC/Cigarette ports, and so always try to use those instead of the AC ones. Try it out: turn on JUST the AC outlets without anything connected. You should be able to measure about 7W of power wasted due to the DC-to-AC inverter being turned on.How long can you use this battery for? It can power up to 519W in an hour. So, if your laptop users 50W of power per hour, that's 50W x 10 hours = 500Wh. The laptop could last for about 10 hours.The built-in wireless charging worked with my Samsung Galaxy S21+ phone, but honestly, it's gimmicky. You waste SO MUCH efficiency charging wirelessly. It's best to plug the phone directly to the USB port.Keep the battery charged between 50-80% when not in use. Don't let it fall below 20%, and don't let it be at 0% for too long, or the Lithium-ion battery cells can become so damaged, it cannot be recharged without deep cycling it with specialized gear.The hard, plastic material used to help shed weight (and cost) could be prone to cracking from hard falls or bumps, potentially exposing the Lithium-Ion batteries to puncturing. The carry handle can be folded, making it not ideal for packing things on top.Functionally, this is a good, portable power station with a multitude of AC and DC outputs.One thing I do not like about this power station, however, is that the AC output is disabled while its battery is charging. Only the DC-based outputs work (USB, 12V) while charging via wall outlet, car cigarette port, or solar. A cigarette port cable is included.CONTINUOUS VS PEAK OUTPUTThe AC Inverter provides a continuous output of 500W with a peak/surge of 1,000W- AC Inverter: Component responsible for converting battery (DC) power into AC for use by electronics- Continuous Output: As long as a device (or combination of multiple ones) does not exceed 500W, it can be used-- Example: A TV that uses 100W can be used because it is less than 500W. You can add more devices as long as they do not exceed 500W combined-- Example: A miter saw I have uses 1,800W, and because it exceeds 500W, it cannot be used- Peak/Surge: Almost every device temporarily draws more power when it is turned on. The highest amount it pulls during that time is the Peak/Surge. This power station can accept up to 1,000W-- Example: A TV that uses 200W (continuous) may temporarily suck up 400W (peak) when powered on. Because 400W is less than 1,000W (peak), this battery will allow the TV to turn on at that level for a few seconds (any longer, and it might cut power as a safety precaution). After a few seconds, the TV then only uses 200W (less than the continuous 500W limit) until the battery is drained-- Example: An unusual device that uses 250W (continuous) and surges to 1,500W when powered on would instantly be shut off by the battery. Why? Even though the device uses just 250W while already on, it jumps to 1,500W when powered on, exceeding the 1,000W surge limit of the power stationCALCULATIONSThe below calculations are rough estimates as conditions, quality, and product age can vary.CHARGING TIMES- Wall charger: 6-7 hours-- AC adapter was observed to provide 70W when charging level was at 67%-- AC adapter will gradually charge slower as battery reaches full capacity (for safety reasons)- 100W solar panel: depending on weather conditions, it should take about 7-9 hours. I did not test this as the winter sun is not very strong-- WARNING: do NOT connect panels sequentially or you may output too much voltage and fry the power station! Connect them in PARALLEL with a Y-Branch cable- Goal Zero Yeti 500x can combine its 8mm and USB-C PD ports for a total input of 180WHOW MANY WATTS DOES A DEVICE US?- Calc: Watts used by device = Voltage x Amperage- If a vacuum is 120V and 9.5A, it uses 1,140WIf a device draws more than 500W for an extended period of time, the power station will shut off as a safety precaution. This can also shorten the battery's lifetimeHOW LONG CAN A DEVICE BE USED FOR?- Calc: Hours available for device = Battery capacity (Wh) x 0.85 / Watts used by device-- Generally, about 10-15% of power is lost during power conversion- If a device uses 60W, it could last up to 3.97 hours (280 Wh x 0.85 / 60W)- Amazon TV I have uses about 100W-- If battery is full at 280 Wh, TV could run about 2.5 hours (280 x 0.9 / 100)HOW LONG DOES IT TAKE TO CHARGE A DEVICE?- Calc: Hours to charge device = Device's battery capacity (Wh) / Input Wattage- If a laptop accepts 60W of input and its battery capacity is 200 Wh, it could take 3.3 hrs to charge (200 Wh / 60W)HOW LONG DOES IT TAKE TO CHARGE THE BALDR 500 WITH SOLAR?- Calc: Hours to charge battery = Battery capacity (Wh) / (Panel Wattage x [0.5 or 0.75])-- In a perfect lab environment, solar panels charge at the indicated wattage (ie. 150W)-- Expect to only receive 50-75% on a good, sunny day (ie. 75W - 113W), depending on environmental conditions, panel's age, and component quality-- Tip: Even if it is overcast, the panels will STILL collect solar energy. Keep charging!- If a solar panel is rated for 100W, it could take as fast as 6.92 hours [519 Wh / (100W x 0.75)] to chargeHOW DOES ITS CAPACITY COMPARE TO POWER BANKS?- Calc: Powerbank-equivalent capacity (mAh) = Battery capacity (Wh) / Voltage x 1000-- 1 Ah = 1000 mAh- A battery capacity of 519Wh at 3.6V is roughly a 144,167 mAh powerbank (519 Wh / 3.6V x 1000) or a 48,056 mAh at 10.8VTIPS- Always test your devices with the power station before you depend on it on the go- Lithium-ion batteries are volatile-- To minimize fire damage to your belongings or loved ones, store the power station in the garage and not inside the house. Best storage is a dry, cool place, however-- You cannot bring a battery of this capacity on a plane- With the right BMS, quality batteries, and other factors, the power station can be stored in the car while camping during a hot, California summer-- Keep the battery out of direct sunlight. I usually store it on the floor of the car and crack open the windows a tiny bit-- Do not USE in the car if temperatures fall below or exceed the battery's rated, operating temperature (32-104F or 0-40C)Keep your car cigarette lighter with the power station -- you could plug it into its 12V DC socket for starting a camp fire- If using a car charger, make SURE you only charge this station while the car is RUNNING. Otherwise, you'll deplete your car's battery and leave you stranded- If charging with a solar panel, be sure to keep the station out of direct sunlight as it could overheat-- A solar panel is NOT required to use the battery-- Rockpals 300 uses the MPPT solar charge controller--- Smarter, more efficient/expensive than PWM--- Suitable for larger systems- Can be used and charged at the same time. Manufacturers’ recommendations for their own products:-- Yes, that’s fine: Paxcess, Goal Zero, Jackery, Rockpals, nrgGo-- No/Not advisable: Suaoki- NEVER charge the power station itself in below freezing temperatures, or you will damage the Li-ion battery AND potentially limit its overall capacity-- You CAN use it to power OTHER devices because the generated heat will warm its battery enough to be within operating temps-- At below freezing temps, keep it in an insulated cooler and connected to a power source (ie. solar panels). The heat generated by the battery will keep it running as best as it can- Turn off any output ports (AC/DC) that are not being used in order to conserve power- Do not use any power station in a tightly enclosed area as it can overheat- To prolong the battery lifetime while in storage, keep the battery fully charged every 3-6 months-- Or, keep it plugged in when not in use and discharge it to 50% every 3-4 months-- NOT using the battery for a very long time can actually hurt its lifetime-- There is no "memory effect" in this station's battery. It is better to NOT let it completely drainFINAL THOUGHTSThe Baldr 500 is a decent battery. The 500W of energy (and peak of 1,000W) provides enough power for a small amount of electronics and small appliances, and is the perfect size for a quick trip or to charge something for a few hours (like my car freezer).The hard, plastic material commonly used by power stations to help shed weight and cost could be prone to cracking from hard falls or bumps, and as such, this product should be handled with care - a puncture of the Lithium-Ion batteries could cause severe harm. I wish the battery's AC port could be used while charging. It has a significant price advantage over the industry leaders.

I got this unit to power my cpap on our boat and rv. My first experience was that it shut down every 3 hours. I did a little investigating and found my Remed cpap without the heater on draws so little power the Baldr 500 sensed it wasn't on. Last night I turned on the heater and it ran for 7 hours and was only down to 75 percent. So far so good. Light weight, versatile with all the power outlets, easy to recharge make it ideal. Hopefully it keeps working.

I preveiously owned a jackery 300, wanted to move up to a 500 watt unit, i had a Baldr solar panel with jackery that i love, so went with their unit, overall its ok, but the AC inverter will not run even run my 150 watt ebike charger that worked fine with my Jackery, let alone anything bigger. I will keep the unit and only use the USB and DC ports, but disappointed.

Charges fast with A/C power. Can be charged by solar power (I bought the 120W solar briefcase from Baldr. It will power many things. I use it with an amateur radio and other items.
